Cómo nadar con cuidado I. Importancia de tener cuidado Aunque ya tienen lecciones de nadar, deben tener cuidado. Nadar es bien divertido, pero puede ser bien peligroso también. Por eso, voy a enseñarles algunas reglas de seguridad. II. Reglas (como discusión con los chicos) Hay muchas cosas que recordar, pero ¿cuáles son las reglas que hay que recordar para nadar con seguridad? Estas son las más importantes: 1. Más que todo, no naden solos. (¿Por qué?) Si nades solo y algo te pasa, no hay nadie para ayudarte. Por eso, siempre nada junto a otras personas. 2. Hay que recordar cuando es mejor nadar. Nunca nades cuando está oscuro afuera- antes del alba y después del anochecer. (¿Por qué?) Si está oscuro afuera, es más difícil ver. Por eso, ni los barcos ni las personas te pueden ver si necesites ayuda. 3. Hay que recordar que todavía están aprendiendo nadar. Es importante no nadar en agua demasiado profunda. (¿Por qué?) Nadar en agua profunda sin salvavidas cuando todavía estás aprendiendo nadar puede ser bien peligroso. Si hacen eso, es más fácil ahogar. 4. Es bien importante saber cuan profunda es el agua antes de tirarte al agua. Tirarse al agua chalote es bien peligroso. (¿Por qué?) Si pegas la cabeza o cuello es mal. Se puede lastimar la cabeza o te puede paralizar. Si no sabes la profunidad del agua, puedes tirar algo para ver. Pero es mejor tener cuidado y no tirarse al agua con la cabeza primera. Para hacer eso, debes tener agua con un profanidad de 2.5 metros. III. Otras cosas que recordar 1. No naden inmediatamente después de comer. Es mejor esperar media hora. Si nadas sin esperar después de comer, es fácil tener calambres. Si tienen calambres, es más fácil ahogarse. 2. Hay que conocer donde nadas. Hay que ver si hay barcos, si hay personas haciendo surf o windsurf, et cetera. También es importante ver el fondo del agua. Hay que ver si hay cosas afiladas, como vidrio. Hay que saber también si hay tiburones o medusas también. Si ves un tiburón: 1. Sal del agua 2. Hay que estar tranquilo. 3. Muda lentamente. Tiburones atacan cuando piensan que eres una amenaza. Si una medusa ataque: 1. No enjuagares el herido con agua. Eso puede emitir más veneno. 2. Usa alcohol para limpiar el herido. Session name Refuse and Pollution Objectives By the end of this session, the students will: 1. Understand how refuse and pollution can negatively affect health 2. Identify the three main types of environmental pollution (air, water, land) 3. Identify five common pollutants that may exist in the local environment 4. Identify behaviors that individuals can practice to decrease environmental pollution 5. Materials Needed Before you begin Time chart Learning Activity Step 1: Step 2: Step 3: Step 4: Total Minutes Step 1: Step 2: Step 3: Step 4: Content Assessment Minutes Session name Tuberculosis Objectives By the end of the lesson students will: 1. Understand what tuberculosis is and how it is transmitted 2. Recognize the signs and symptoms of TB 3. Know the treatment for TB and how to avoid further spread of the disease 4. Understand the concept of drug resistance and why this is so common among TB patients 5. Understand how medications should be taken in order to avoid the development of drug resistance. Materials Needed Spray bottle Before you begin Time chart Learning Activity Step 1: Step 2: Step 3: Step 4: Total Minutes Minutes Step 1: What is Tuberculosis and how is it transmitted? Ask the students to point to their lungs. Ask them why our lungs are important and what their function is. Ask them to hold their breath for 10 seconds. Can you see how important the lungs are? Emphasize that we need our lungs all the time. Tuberculosis is a very serious disease that damages the lungs. TB can make you very sick for the rest of your life or even kill you if it is not treated. Many people die each year from this disease. Tell the students that we are going to talk about and demonstrate how many people in the world have tuberculosis. Have the students stand up. Tell them that out of 6 billion people in the world, 2 billion people have TB. To help them to see how many people are infected, tell 1/3 of the class to remain standing. These students represent the number of people in the world with TB. Explain to the students that even though this many people have TB in their bodies, most people’s bodies are able to fight the disease. Because of this, they never actually feel sick even though they have the disease. In fact, many people have TB for many years before they even start to feel sick. Usually, one out of every 10 people with TB gets very sick. Have all the students sit down except one who has been previously identified as the TB patient who actually gets sick. TB is easily spread from person to person through the air when a person sick with TB coughs, sneezes, sings, laughs, or even talks. Let’s look at how easily TB is spread. Take the student who was selected as “sick” with TB. Give him/her a spray bottle. Tell everybody that the water in the spray bottle represents the saliva that contains the TB germs. Have the infected person walk around the room coughing, singing, and sneezing. While coughing, etc. have the infected person spray 10 more people with the water bottle. Explain to the students that each person who is sick with TB can make 10-15 more people sick each year. Those who have been sprayed with the water are now infected with TB. Remind them that one of every 10 people who has TB will actually get sick. Pick one more person to be sick with TB. Now there are 2 people who are sick with TB. They can now walk around the room coughing, etc. Continue this exercise until every student in the class has TB. Step 2: Signs and symptoms of TB Because TB is a disease that affects our lungs, what types of problems do you think a person with TB would have? Dificultad de respirar Tos Tos con sangre Fatiga Debilidad Pérdida del apetito Pérdida de peso Fiebre Malestar Dolores en el pecho After you have talked about the signs and symptoms, divide the class into 2 groups and have each group list as many signs as they can in 1 minute. The team that lists the most correct symptoms wins. Step 3: Treatments for TB Even though TB can make us very sick and is easily transmissible, it is also treatable. People who have TB can be cured of the disease if they follow the proper treatment schedule. TB is treated by taking medication (usually pills). In order for the treatment to work, the pills are taken for 6-9 months. Many people are never cured of TB because they do not take their medications the way they are supposed to. This is a very big problem because if people don’t take all of their pills the way they should, the TB germs can become more powerful and make it so the medicine will no longer work. This is called drug resistance. If the medicine no longer works, then people who have TB cannot get better. To show the students how drug resistance works: get a group of students to come forward and form a tight circle by sitting cross legged and linking arms; explain that this circle represents the medication that will cure TB. Have a few other students come forward. Tell them that they are meant to represent the TB bacteria and that they are trying to make someone sick by getting on the inside of the circle. At first, tell the “TB” that they have to be lying flat and that they are not able to touch anyone else as they try to get into the circle (this should be very difficult, if not impossible). Explain that this represents effective functioning of medication. Then, tell them that they can stand up, jump and move freely as they try to get into the circle (still without touching anyone else)…it should then be very easy to get into the circle as they are able to simply step over the students who are forming the wall. Explain that when medication is not properly, germs (such as TB) can change to become bigger and stronger. When this happens, the medication no longer works to prevent the person from becoming sick. Tell the students what they can do to prevent medications from becoming ineffective. Take only medication given to you, specifically, by a doctor. Take all of the medication given to you, even if you start to feel better Take the proper amount of medication, and at the proper times Do not share your medication with others, even if they have the same sickness Be clear on what medications you are supposed to take Do not skip days (doses) **Option: to give example of scenarios when medication was taken wrongly (e.g. Juan becomes sick and his aunt tells him that she has some pills that he can take, pills which she got from the doctor last time she was sick; OR Maria was given pills from the doctor that she was supposed to take for 7 days. However, after two days, she began to fell better and so stopped taking the pills; OR Pablo forgot to take his medication one day, so he took two extra pills the next day; OR Hosea could not remember which pills he was supposed to take so on one day, he took two of the red and one of the white, and on the next day took two of the white and one of the red). Step 4: How can you prevent the spread of TB? Wash your hands Cover mouth when coughing or sneezing If you know you are sick with TB, avoid contact with others or wear a mask If you have been in contact with someone who has TB, go to the doctor and get tested for TB If you are taking the medication for TB, take it properly. Content Assessment Session name Water cycle and supply Objectives By the end of this session, students will: 1. Demonstrate an understanding of why water is necessary for life (in all living things) 2. Understand the water cycle (within the environment) 3. Understand the negative impact that humans can have on water availability and quality 4. Identify five ways that water can negatively impact health 5. Explain different ways that water can be purified so that it does not negatively affect health (e.g. boiling, purification tablets, solar purification, etc.) Materials Needed Picture of a desert and a forest Liter bottle Paper Drawing utensils Bucket Water (bottled/clean) “Contaminants” such as dirt, spices, sand, rocks, food coloring, wrappers, paper 3 glasses Cloth Before you begin Thoughtfully review all material in the lesson plan, focusing especially on the content area to assure you have a firm educational basis for teaching. Think through your teaching strategies and anticipate potential problems or difficulties that may arise. Remember to adapt each session to your audience, keeping in mind their needs and abilities. Prepare all materials: Time chart Learning Activity Step 1: Water is essential to life Step 2: Where does water come from? Where do we get water for every day life? Step 3: Water contaminants Step 4: How can unclean or lack of water negatively affect health? Step 5: Water purification Total minutes Minutes 10 15 20 Step 1: Water is essential to life In order to establish the importance of water, start by giving the students several facts about water. Examples: 70% of human body is water. Amount of water in an average adult is 37 liters. A human can live almost a month without food, but can only live 1 week without water. Water regulates the temperature of the body and of the Earth. You should drink 2 liters of water a day to stay healthy. Water removes waste from the human body. 75% of Earth is covered with water. 3,900 children die every day because of poor sanitation and lack of safe drinking water. Show the students a picture of a desert alongside a picture of a lush forest. Ask them what the difference is between the two pictures. What element do they think is missing from the picture of the desert? Discuss how water is vital for all living things. Plants, animals, and humans cannot live long without water. With the students, brainstorm (or have students act out) ways that water is used. Ask them how they use it in their homes, their neighborhoods, and at school. Help them to see how often we use water and how essential it is to every day life. Step 2: Where does water come from? Where do we get water for daily life? Now that we know how important water is, we are going to talk about where it comes from. Tell the students that ever since the Earth was created, water has been circulating through what is called the “water cycle.” Have the students help you draw a picture of water cycle. Have students begin by drawing clouds with rain falling from them. Ask the students what happens to the rain once it falls. Keep drawing as you discuss how when rain falls, some of it goes to streams and lakes (surface water). Some of the water is used by plants, and some is absorbed deep into the ground (ground water). What is not used is evaporated by the heat of the sun. This evaporated water forms new clouds in the sky, which then produce rain, and the cycle begins all over again. Water is supplied to people through many different means (e.g. ground well, rivers, lakes, irrigation). Have the student identify and discuss where they and their families get water. Step 3: Water contaminants Ask the students if they have ever seen water that looked really dirty. How do they think it got so dirty? Tell the students that we are going to talk about the things that we (as humans) do to make water dirty. Fill a large bucket with water. Cover it so that the students cannot see the water. Give each student a different small “contaminant” that they can drop into the bucket. As the students drop their contaminant into the bucket, ask them to think of what it could represent in their community (e.g. the dirt could be excrement, wrappers could represent trash, etc.) As the students put their contaminants in, comment that each of them is only putting a little object in. Once all the students have participated, lift the cover from the bucket and show them how contaminated the water has become. Even though each person only dropped a little amount into the bucket, it still has become very dirty. In this bucket of water, we can see that the water is dirty. Sometimes, water can be dirty, but you can’t always see the dirt (i.e. it may have germs that are too small for your eyes to see). This is especially dangerous when we use this water for drinking and cooking, because the germs can make us very sick. Tell the students that we are going to demonstrate how even when we can’t see the dirt in the water, it can be dirty. Fill up 3 glasses of water: one the looks dirty (add a non-harmful substance that will make it appear dirty – e.g. coca or bean juice), and two that appear clean. Have three volunteers come up and drink the glasses of water. Prior to their drinking the water, take the three volunteer students out of the room and instruct them as follows: the one who drinks the dirty water must pretend to become ill; the one who drinks the clean water will act fine, and the third person who drinks the clean looking water will pretend to fall dead. Reiterate that his demonstrates how dirty water can affect out heath and how sometimes it is difficult to tell when water is actually dirty. Step 4: How can unclean water or a lack of water negatively affect health? Dehydration Diarrhea Other sicknesses (Typoid, Cholera) Contamination of crops Death of crops Inability to properly clean self and home Cannot feed/water animals Cannot properly cook food Step 5: Water purification There are several ways to make sure that we don’t get sick from bad water. One of these is to make sure that we get water from the right source. Another is making sure that we protect the source of our water. We can also use different methods to clean our water. Once our water is clean, we can also make sure that it stays clean by storing it properly. First, we’re going to talk about how water can be cleaned if it is dirty. There are four main ways to clean water: boiling, filtration, solar disinfection, and chemical tablets. Some ways are better than others at cleaning our water. Boiling: boil for 5-10 minutes Filtration: use tightly woven cloth and pour water through cloth into container Sedimentation/Solar disinfection: use 2-liter bottles and place them in the hot sun for 6-8 hours Chemical: dissolve hypochlorite or iodine tablets in water (use only as directed) Once your water is clean, it is safe for drinking and use. However, we need to make sure that we keep it clean by storing it in clean containers with lids. We also need to make sure that we don’t introduce anything that would make the water dirty, like our hands, or dirty serving utensils. *Optional: demonstrate filtration using tightly woven cloth and the water the students “contaminated” in the previous exercise. Content Assessment. Ask students to go home and find out where they get their water. Have them find out if their water is clean, and how their families make sure their water is clean. Have them write their findings (or draw pictures) in their health journals. Discuss what they found at the beginning of the next lesson. Healthy Teeth Lesson 1) Discussion a. What does it mean to be healthy? (Eat well, work out, be clean) b. How do we stay healthy? c. Why do we have teeth? (Eating, talking, smiling) d. What can we do to keep our teeth and mouth healthy? (Brush teeth, etc.) e. Today we’ll learn a little bit about how to keep our teeth healthy… 2) Brushing Teeth Race a. Split class into two teams (boys vs. girls, by birthdate, etc.) b. Prepare a “tooth” (bottom half of a 2 liter bottle covered in shaving cream) for each team at the front of the classroom c. Start race at other side of classroom and perform a relay race with each member running to the tooth, brushing it with a toothbrush, and giving the toothbrush to the next runner. d. The team with the cleanest “Tooth” by the end of the race wins 3) Brushing Teeth Lesson a. Hand out real toothbrush to each kid b. Show the correct way to brush teeth and how long to do it c.

Have children draw and cut out their teeth and lips from the paper c. Attach a piece of yarn to each side d. Help each child put on their beautiful mouth! Session name Nutrition and Health Objectives By the end of this session, students will be able to: 1. Identify different ways that nutrition affects health 2. Possess a basic understanding of the gastro intestinal tract and how food is absorbed and used by the body 3. Identify and list the five basic food groups 4. Be able to categorize different foods into the proper food groups 5. Identify different conditions/illnesses caused by poor nutrition Materials Needed Chalk (preferable sidewalk chalk) Picture of the food pyramid and the four types of food groups Paper and markers Before you begin Thoughtfully review all material in the lesson plan, focusing especially on the content area to assure you have a firm educational basis for teaching. Think through your teaching strategies and anticipate potential problems or difficulties that may arise. Remember to adapt each session to your audience, keeping in mind their needs and abilities. Prepare all materials Time chart Learning Activity Step 1: Step 2: Step 3: Step 4: Total Minutes Minutes 25 20 20 25 90 Step 1: GI Tract Large group activity and discussion (25 minutes) Draw a picture of the GI tract on cement with chalk. Have different kids act out the various parts of the GI tract (Mouth, stomach, sphincter, intestine, ect). Take a few kids and tell them that they are “food” for the body. Have them walk through the digestive tract while the other kids are acting out the motions of the mouth, throat, stomach, intestine, etc. As they walk through the parts of the tract, explain what each part is doing to help digest the food (how it works). Explain that the body needs food and the nutrients found therein in order to function. (It’s like fuel: if you don’t put gas in a car, it won’t run. Food acts in the same way: it helps our bodies to function effectively). Think about how you feel when you are really really hungry…can you describe that feeling? Be sure to point out that not everything in food is needful or good for the body; there are also products that result from the breakdown of food. These wastes from the food we eat are why we go to the bathroom (caca). The mouth is the entry to the digestive system. Food enters the mouth where teeth hold, tear and grind food. The tongue is responsible for moving the food around the mouth. Saliva then starts to chemcially digest the food, turning in into a watery mixture that can easily pass into the stomach. The throat is a connecting tube between the mouth and the esophagus, which in turn links to the stomach. The tonsils are at the enterance of the throat, and can become inflammed in a condition known as tonsilitis. Food is carried along the esophagus by muscular contractions called peristalsis. Food is stored and digested in the stomach. The stomach contains hydrochloric acid and other important enzymes which chemically break down the food, releasing the nutrients. Muscular contractions move the partially digested food around the stomach. Nutrients are absorbed in the small intestine. Divided into three sections, the small intestine continues to break down the food and releases the nutrients into the bloodstream so they can be passed around the body. It has a very large surface area due to the villi along its walls which help absorption. The liver processes and distributes nutrients. The liver creates bile, which is important in chemically breaking down the food in the small intestine. It also processes damaged red blood cells and stores vitamins A and D. When there is no food in the small intestine bile from the liver is sent to the gall bladder where it is stored in a concentrated form, to be released when food enters the digestive tract. The pancreas produces pancreatic juice. The pancreas makes enzymes which are released into the small intestine to break down the food. It neutralises the hydrochloric acid from the stomach, makes the enzyme to stimulate the liver into producing bile and secretes insulin which transports sugar. Faeces are stored and expelled by the large intestine. Bacteria in the large intestine act on the waste product while water and some salts are absorbed through the intestinal wall. The remaining product is faeces, a combination of bacteria, undigested food and other waste products. The appendix is found off the large intes Step 2: What goes into your digestive tract? Divide the class into small groups (4 people); have them draw (or write) down the most common foods that they eat. Have them circle their favorite food, and have them but a box around the food they eat most frequently. Have each group share with the rest of the class what they came up with. Initiate a group discussion about which of these foods they think are healthy (why or why not?) and which are not healthy (why or why not?). Ask them about other foods (that are not in their pictures) that they think are either healthy or not healthy. Step 3: Outlining the five food groups Game All of the foods that we have been talking about can be categorized into six main food groups: Grains Fruits Vegetables Protein (meat and poultry) Dairy Sweets and Fats Assign each student a food from a different food group (e.g. banana, milk, bread, steak, etc.). Assign different areas in the room to various food groups (e.g. one corner is fruits, one area is proteins, etc.). Have the students mingle in the center of the room, and tell them that when their food group is called, they need to hurry to their assigned area. Call each food group several times until they have understood which foods are characterized in which groups. Tell the students that when you call “balanced meal,” they have to combine with a food from each food group to make a complete meal. Call “balanced meal” several times so that they can see different combinations of foods and how they might prepare meals with different food groups. Step 4: Illnesses related to nutrition Large group discussion and personal reflection (25 minutes) Tell the students that what we put into our mouths can affect our health. Throughout the course of the camp, we will be talking about some illnesses caused by improper nutrition. Some illnesses and diseases are caused by eating too little of important nutrients, while others are caused by eating too much. Too little: Lack of iodine - salt Lack of calories and energy Lack of vitamin B1 – beef, pork, spinach, green peas, whole grains Lack of vitamin D and calcium – cheese, milk, yogurt Lack of vitamin C – citrus fruits, carrots, guava, papaya, greens Too much: Obesity Diabetes Content Assessment Session Name Natural Disaster Safety Objectives By the end of this session the students will be able to: 1. 2. 3. 4. Describe hurricanes and how they happen. Understand how to be safe during a hurricane. Make a plan during an emergency. Large round bowl or tub of water Spoon Food coloring with a dropper top White paper Crayons Materials Needed Before You Begin Time Chart Learning Activity Minutes Discussion 5 Science of Hurricanes 5 Hurricane Safety 20 Hurricane Necessities 15 Conclusion 5 Step One: Discussion (5 minutes) Ask the children the following questions to see what they already know and any misconceptions that they may have. 1. 2. 3. 4. 5. Can anyone give me an explanation or example of a natural disaster? Has anyone ever been in a natural disaster? What causes a hurricane? What should we do if there is a hurricane? What should we do if there is a fire? Thank the children for their answers and tell them that we are going to learn all about some natural disasters today. Step Two: Science of Hurricanes Ask students if they know what causes a hurricane. Draw the following picture and explain these characteristics. They are tropical, meaning that they are generated in tropical areas of the ocean near the Equator. They are cyclonic, meaning that their winds swirl around a central eye. Wind direction is counterclockwise (west to east) in the Northern Hemisphere and clockwise (east to west) in the Southern Hemisphere (more about this later). They are low-pressure systems. The eye of a hurricane is always a low-pressure area. The lowest barometric pressures ever recorded have occurred inside hurricanes. The winds swirling around the center of the storm have a sustained speed of at least 74 mph (119 kph / 64 kt). Help the students make their own hurricane in a bowl with this experiment: 1. Moving the spoon in a circular motion around the side of a bowl, stir the water. 2. When the water is moving fast, stop stirring and immediately put several drops of food coloring into the center of the swirling water. The color will move out from the center forming bands—much as clouds in a hurricane do. Step Three: Hurricane Safety (20 mins.) Divide the class into three groups and assign each a topic. The groups will be in charge of brainstorming about the topic and presenting their information to the class. The topics are: 1. What to do before the hurricane 2. What to do when a hurricane hits your community 3. What to do after a hurricane passes Give them ten minutes and visit each group to help them develop their discussion. After each group presents, expand on their comments and cover anything they missed. What to do before the hurricane Tape windows by cris-crossing, or making X’s on the window to prevent the glass from flying around if the window is broken. Put boards or shutters over big windows. This will help the window from being broken or debris flying into your house. Store extra water in bathtubs, jugs or any other container (Strong hurricanes have been known to break water mains). Pick up loose objects in the yard such as toys, lawn equipment and flower pots. Hurricane winds can reach over 100 mph, and can make bullets out of these common objects. Fill the car with gasoline in case you need to evacuate the area. Turn the refrigerator to maximum cold and open it only when needed. Bring in outside pets. Stay tuned to the news. Be sure to have a battery operated radio and extra batteries in case the electricity goes out. Be sure you have these items flashlights and extra batteries bottled water battery operated radio and extra batteries canned goods with hand held can opener special medications candles, waterproof matches, lantern with oil first aid kit What to do if a hurricane hits your community Beware of tornadoes. Leave the area if officials order an evacuation or if you live in low lying areas. Stay tuned to the news for evacuation notices along with updates to the storm's intensity and position. If you are evacuating, leave as early as possible to avoid congestion on the roads. Have a plan on where to go in the event of an evacuation. If you are going to ride out the storm, stay inside. Watch for flying boards, trees, downed power lines and other objects that could be carried by the strong winds. Beware of the eye of the hurricane; this calm section in the middle of the hurricane is not to be taken lightly. It only means that half of the storm has passed, even though the sun may come out. Check and adjust objects on your property (if needed), then return to safety inside. What to do after the hurricane has passes Avoid power lines that have fallen to the ground. Beware of poisonous snakes and other deadly animals, as the rising water forces many animals inland. Watch for weakened bridges and washed out roads. Watch for spoiled foods and do not drink the tap water until you are certain it is not contaminated. Watch for weakened tree limbs. Don’t use the phone unless it is an emergency. The phone lines can be jammed with calls that make it difficult for emergency calls to get through. Step Four: Hurricane Necessities (15 minutes) Pass out paper and ask each of the children to draw one object they think they would need in a hurricane. Give them ideas like flashlights and extra batteries, bottled water, battery operated radio and extra batteries, canned goods with hand held can opener, special medications, candles, waterproof matches, and a first aid kit. After they are done drawing, let students share their drawing and how it would help them during a hurricane. Step Five: Conclusion (5 minutes) Thank the students for their participation in the lesson. Recognize the risk of hurricanes and the importance of preparing for natural disasters. Emphasize the points shared in the lesson and encourage them to discuss emergency preparedness with their families. Session Name Illegal Drugs Objectives By the end of this session the students will be able to: 1. 2. 3. 4. Describe illegal drugs and how they affect the body. Understand the consequences of illegal drugs. Say no to peers who want them to try drugs. Make dreams and goals for their lives. Materials Needed Chalk board Chalk Hangers Crayons Construction paper String Time Chart Learning Activity Minutes Discussion 5 Consequences 10 Making Decisions 15 Dream Mobiles 20 Conclusion 5 Step One: Discussion (5 minutes) Ask the children the following questions to see what they already know and any misconceptions that they may have. What is an illegal drug, and what is a harmful substance? The students’ responses should be listed on the board and grouped as follows: Illegal drugs: • Alcohol, which is forbidden by law to be sold to minors • Any drug that is not prescribed by a physician Harmful substances: • Aerosol products, such as spray paints, hair spray • Vaporous liquids, such as gasoline, lighter fluid, airplane glue, paint thinner, nail polish remover, correction fluid, and cleaning fluid Why would someone want to do drugs? • To rebel, to go against parents or other authority • To feel good, to get “kicks” • To relax, to forget about problems • To be “one up” on others, to feel older, more sophisticated • To feel that you belong, to be “in” with a group, to keep from being lonely • To be able to do things without feeling guilty, things that a person would not usually do • To satisfy a dependence on the substance Step Two: Consequences of Drugs (10 minutes) This step should inform the students of the numerous short and long-term consequences. Draw three big circles on the board and title them emotional, physical, and social consequences of taking drugs. Have the students name consequences and tell you which category they fit into. These consequences could include disappointing parents, bad grades, offending friends, or getting sick. Discuss each in detail and how they would affect the students’ lives. Step Three: Making Decisions (15 minutes) Divide the class into groups of 3-4 and give them each a scenario to act out. These scenarios should be tailored to the age and environment of the students. The students should act out the scenario and what would be the best decision to make. Give them 5 minutes to practice their skit and then have each group perform for the class. Point out the good decision the students make and how to deal with the situations. Step Four: Dream Mobiles (20 minutes) Talk to the students about the long-term consequences of drugs. Give examples of how they can get in the way of their dreams. Stress the importance of keeping goals for the future in mind. Show them an example of a dream mobile. Assist them with this project. 1. Pass out construction paper and crayons 2. Have students cut 5 strips of paper 2-3 inches wide. On one strip have them write, “I will say no to drugs because I have dreams.” On the rest of the strips have them write goals or dreams they have. 3. Have the students glue the strips into a circle 4. Pass out pieces of string and hangers 5. Have the students tie one end of the strings to the hanger and one end to the circles Invite students to come up and share their dream mobile with the class. Step Five: Conclusion (5 minutes) Thank the students for their participation in the lesson. Recognize the risk of drugs and the importance of avoiding them. Emphasize the points shared in the lesson. Encourage them to hang their mobiles in their rooms so they can remember all the reasons why they should avoid drugs. Session name Germ theory/Transmission of disease Objectives By the end of this session, students will: Understand what germs are Understand how germs can cause disease Identify places where germs exist (Identify different types of microorganisms) Identify routes of transmission 1. 2. 3. 4. 5. 6. Materials Needed Magnifying glass/microscope/binoculars Pictures of different types of germs Shields Elastic bands or scrap paper Before you begin Thoughtfully review all material in the lesson plan, focusing especially on the content area to assure you have a firm educational basis for teaching. Think through your teaching strategies and anticipate potential problems or difficulties that may arise. Remember to adapt each session to your audience, keeping in mind their needs and abilities. Prepare all materials. Time chart Learning Activity Minutes Step 1: What are “Germs” (Group Discussion) 10 Step 2: How can germs get into our bodies? (Discussion and Activity) 20 Step 3: How does the body protect itself from germs? (Discussion and Activity) 15 Total Minutes 45 Step 1: What are germs? Large group activity and discussion (10 minutes) Brainstorm with the kids: What is the biggest animal you can think of? What is the smallest animal you can think of? There are things even smaller than an ant. Use a magnifying glass to show how much bigger things become. Show grains of dirt or dust. There are things so small that our eyes cannot see them. There are lots of things that are this small. There’s a whole world of unseen objects. One of these “unseen” objects are what we call “germs” (puppet). In the scientific world, they are also referred to as microorganisms. Germs are like tiny animals. These animals can cause harm to humans if they are able to get inside the human body. They are the cause of many diseases and can make people very sick…What are some diseases that you can think of? (diarrhea, malaria, pneumonia, colds, flu). Many or all of these are caused by some sort of “germ” (of which there are different types – e.g. fungi, bacteria, protests). Germs are found everywhere on the earth (e.g. in water, on surfaces, in soil, in our bodies). Show pictures of germs… Step 2: How Do Germs get into our Bodies? (i.e. how are they transmitted from the environment into the human body?) In order to make you sick, these germs have to get into the body. How do you think germs can get into your body? 1. 2. 3. 4. Inhalation Ingestion Absorption (skin) Blood or body fluids Put pictures of a mouth, skin, nose, blood into a container. Have a child come up to the front and draw out a picture. Have the child act out how a germ could enter the body through that body part. Use the germ puppet to demonstrate (or a straw with a picture of a germ on it). Activity for Step 2: Put 4 methods on the board. Divide the class into 2 teams. Tell them that you are going to give specific examples of where germs are found. Ask them how the germs are going to be transferred from the thing into a human body (through which route of transmission?/body opening). Examples: Mosquitoes Banana Water Dust/particles River Hands Desk/table Pesticides? Chemicals Parisites (scabes) Dog Your girlfriend/boyfriend Step 3: How are our bodies naturally protected from germs and disease? Skin Hair Mucous membranes Immune system Explain how the body uses these different methods to protect itself form germs. Then…have “shields” made (with cardboard or plastic or cloth) with the names written of these different protective barriers. Have kids come to the front of the room and use these shields to protect themselves, while the other kids in the room are shooting elastic bands or throwing balled up paper at them. IF they are not successful at shielding the germs (i.e. if they get hit) then they have to fall to the ground. This demonstrates that even though our bodies have protective barriers, sometimes germs are effective in finding there way into the body. Conclusion Explain that it is very important to be aware of germs and how they can cause disease and sickness. Germs play a large role in our health and that is why it is necessary to understand their existence and how they affect us so that we can better protect ourselves from them. Content Assessment Session name Family health Objectives By the end of this lesson, students will: 1. Have drawn a genogram of their family in their health journals, using the proper symbols. 2. Begin to understand how family relationships affect health (social relationships) 3. Identify ways that the illness or health of one family member can impact lives of other family members. 4. Have a basic comprehension of “heredity” and identify 3 illness that can be passed from one generation to the next. Materials Needed Paper and writing utensils Genogram symbols legend Case scenarios Before you begin Time chart Learning Activity Minutes Step 1: Step 2: Step 3: Step 4: Total Minutes Step 1: Genograms A “genogram” is a simple picture display of family relationships and medical history. Have each student draw a genogram of three generations of their family – their grandparents, parents, and themselves (see attached content material for example and instructions on genogram symbols). Have them identify simple social relationships on their individual genograms, using the appropriate symbols (for example, two diagonal slashes between people means that they are divorced; solid parallel lines means that two people are very close and have a positive relationship; a jagged line means that there is abuse; ect.). Also have them write or diagram certain diseases or illness that family members have (e.g. heart disease, diabetes). If they do not know specific diseases, have them describe the symptoms of the ill individual. Step 2: The concept of Heredity Heredity is the idea that certain characteristics are transferred (handed down or given) from parents to their children through biological functions (i.e. genes). Have students identify ways that they feel they look like their parents, or specific traits that they think they have inherited from their parents (e.g. curly hair, brown eyes, big/small nose, laugh, ect.). Have them share some of these things with the rest of the class. These identified characteristics are examples of things that are hereditary. Some illnesses or disease are also hereditary as they can be passed from one generation to the next. Examples of hereditary diseases include: Diabetes, Heart Disease, Some cancers, depression, Alzheimer’s, Alcoholism. It is important to know what diseases are common in your family so that you can do things to prevent them from developing or can treat them properly. Stress that not all diseases are hereditary and that even those which are will not necessarily be passed on to all family members. Step 3: How illness or health of one family member affects others in the family. Divide the class into small groups (4-5 people). Give each of them a short case scenario to discuss. Example case scenarios are as follows: 1. 2. 3. 4. 5. Your mother just had a new born baby You dad lost his job Your little brother is sick with diarrhea You have Dengue fever Your grandmother comes to live with your family because she is too old to care for herself 6. Your grandfather broke his hip when he fell 7. You and your sister always fight 8. Your parents are getting a divorce When discussing these case scenarios in their individual groups, have them answer the follow questions: 1. 2. 3. 4. 5. How this makes you feel? How does this affect you personally? How does it affect other family members? How can you help to improve the situation? How might this make it difficult to do regular daily tasks (e.g. going to work, gathering food/water, going to school, playing with friends, doing chores/housework Have each group share there answers (what they discussed) with the rest of the class. Content Genogram From Wikipedia: http://en.wikipedia.org/wiki/Genogram A genogram is a pictorial display of a patient's family relationships and medical history. It goes beyond a traditional family tree by allowing the user to visualize hereditary patterns and psychological factors that punctuate relationships. It can be used to identify repetitive patterns of behavior and to recognize hereditary tendencies. Genograms were first developed and popularized in clinical settings by Monica McGoldrick and Randy Gerson through the publication of a book titled Genograms: Assessment and Intervention in 1985. Genograms are now used by various groups of people in a variety of fields such as genealogy, medicine, psychiatry, psychology, social work, genetic research, education, and many more. Some practitioners in personal and family therapy use genograms for personal records and/ or to explain family dynamics to the client. Few if any genealogists yet use them. [edit] Genogram symbols A genogram is created with simple symbols representing the gender, with various lines to illustrate family relationships. Figure 1 illustrates basic genogram symbols with various types of individuals. Some genogram users also put circles around members who live in the same living spaces. Genograms can be prepared by using a complex word processor, or a computer drawing program. There are also computer programs that are custom designed for genograms. Genogram symbols will usually have the date of birth (and date of death if applicable) above, and the name of the individual underneath. The inside of the symbol will hold the person’s current age or various codes for genetic diseases or user-defined properties: abortions, still-births, SIDS, cohabitations, etc. [edit] Genogram content A genogram can contain a wealth of information on the families represented. It will not only show you the names of people who belong to your family lineage, but how these relatives relate to each other. For example, a genogram will not only tell you that your uncle Paul and his wife Lily have three children, but that their eldest child was sent to boarding school, that their middle child is always in conflict with her mother, that their youngest has juvenile diabetes, that Uncle Paul suffered from depression, was an alcoholic, and a philosopher, while Aunt Lily has not spoken to her brother for years, has breast cancer and has a history of quitting her jobs. Figure 2 illustrates that genogram. [edit] Family relationships One of the advantages of a genogram is the ability to use colour-coded lines to define different types of relationships such as family relationships, emotional relationships and social relationships. Within family relationships, you can illustrate if a couple is married, divorced, common-law, engaged, etc. Figure 3 illustrates the symbols commonly used for family relationships. [edit] Emotional relationships Genograms usually also include emotional relationships. These provide an in-depth analysis of how individuals relate to one another. Colour-coded lines represent various emotional relationships that bond individuals together. In Figure 2, the double dotted line between Lily and Natalie illustrates discord, the line with red stripes illustrates distrust between Paul and his son Andrew, and the broken line between Lily and Frank illustrates a cut-off relationship. Figure 4 illustrates the symbols commonly used for emotional relationships [edit] Social relationships Another component of genograms is social relationships. These allow users to link individuals who are not related to one another, but who have a connection in society-at-large, such as neighbor, co-worker, bossemployee, pastor-church member, teacher-student, etc. Social relationships can also illustrate an individual’s relation to a social entity like Andrew and the boarding school in Figure 2. The use of social relationships links allows the genogram to be used in a business environment to create organizational charts or floor plan layouts of the employees. A genogram looks like a family tree, but with all the different types of relationships, it contains a significantly more detailed and complete picture of the family or group it illustrates. [edit] Purpose of the Genogram [edit] Genealogy In genealogy, genograms are used to record family history through the lives of each of its members. Genograms allow the genealogist to graphically portray complex family trees that show marriages and divorces, reconstituted families, adoptions, strained relationships, family cohesion, etc. Genealogists can use genograms to discover and analyze interesting facts about their family history, such as a naming pattern, sibling rivalry, or significant events like immigration. [edit] Medicine In medicine, medical genograms provide a quick and useful context in which to evaluate an individual's health risks. Knowledge of diseases and conditions that occur within a family can give a health care team invaluable information that may aid in a swift, accurate diagnosis and treatment of health problems. And, a knowledge of diseases and illnesses that "run" in families can give individuals an important head start in pursuing effective preventive measures. A medical genogram is helpful in determining patterns of disease or illness within a family. Medical genograms can include many generations, however four generations may prove to be enough detail. Figure 5 illustrates a user-defined legend for a medical genogram. [edit] Psychology In psychology, genograms are used by psychologists to gather objective and consistent information from the clients and their family, helping them to view the client’s issues in the larger context of their marital relationship, family relationships and culture of origin and underlining key issues to discuss in client counseling. Genograms portray emotional relationships, which allow psychologists to see and evaluate possible conflicts within the family. [edit] Social work In social work, genograms are used to display emotional bonds between individuals composing a family or social unit. A genogram will help social workers to make an assessment of the level of cohesiveness within a family or a group and to evaluate if proper care is available within that unit. Genograms also allow displaying social relationships that illustrate the places people attend such as schools, churches, youth facilities, associations or retirement homes. [edit] Research In research, genograms allow researchers to understand multi generational processes within various plant and animal species, such as the development of mutations. Genograms can also illustrate rates of renewal, mechanisms of survival, or processes involved in the regulation of tolerance, among other things. [edit] Education In education, genograms can be used by teachers and students for illustrating book reviews, or family trees of a famous politician, philosopher, scientist, musician, etc. They allow them to focus their attention on specific details and also see the big picture of the books and individuals they are studying. [edit] Creating Genograms Genograms can be useful in almost any profession that deals with social interaction. Genograms can help to visualize complex interactions between individuals and to study patterns of behaviors or diseases. Genograms are best created with genealogy software, as advanced software allows the user to include tremendous amounts of data. Genealogy software also allows the user to create detailed reports containing analysis of the information stored in each person’s individual properties. Genograms are often drawn by hand, sketched working right with the client. It is also possible to create a Genogram using MS Word. [edit] External Links Assessment Session name Disposal of human waste Objectives By the end of this session, students will: 1. 2. 3. 4. Understand the fecal-oral route of disease transmission Explain how improper disposal of human waste can negatively affect health Identify 3 ways to properly dispose of human waste Understand what can be done to prevent fecal-oral diseases Materials Needed Something that represents fecal matter (raisins, pebbles, paper, etc.) (Baby doll) Fecal-oral pictures Fecal-oral disease transmission figure Powder or spices Food (either real or cut-outs of food) Before you begin Thoughtfully review all material in the lesson plan, focusing especially on the content area to assure you have a firm educational basis for teaching. Think through your teaching strategies and anticipate potential problems or difficulties that may arise. Remember to adapt each session to your audience, keeping in mind their needs and abilities. Prepare all materials: Time chart Learning Activity Step 1: Fecal oral cycle of disease Step 2: How can we properly dispose of waste? Step 3: How to prevent fecal-oral diseases Minutes 25 15 5 Total Minutes 45 Step 1: Fecal oral cycle of disease How many of you would eat poop? Why would you not eat poop? You may be eating poop without even knowing it. We have talked about how germs can be found everywhere. One place where we can find lots of germs is in fecal matter (heces). If we are not careful, the germs from fecal matter can get on our hands, in our food and in our water. Many times when we get sick it is because germs from fecal matter get into our food and water. These types of diseases are called fecal-oral diseases. Show the students the fecal-oral cycle figure. Divide the students into 5 groups. Have students think of a specific way that germs could travel from fecal matter to our mouths. Offer a couple of examples - either from the pictures provided or from your own experience - to help them start thinking about how germs are transmitted. As we said, the germs from fecal matter can make us very sick. We are going to demonstrate how we can get sick from these germs. Have the teacher(s) or volunteers act out the following scene: Volunteer 1 (mother): The mother is rushing around the house, going to the bathroom, cleaning, and changing the baby’s diaper. After she has done a few different tasks, have her say, “I’ve been so busy today that I haven’t even had any time to wash my hands.” The mother then shows the “audience” her hands, which are covered in powder/spices. Volunteer 2 (daughter): The daughter is outside playing in the dirt. She then goes to the bathroom outside by the house. Volunteer 1 (mother): The mother then calls in her daughter to help her with dinner. Volunteers 1 & 2 (mother and daughter): When the daughter comes inside have her show the “audience” her dirty hands. Have the mother and daughter begin to prepare dinner for the family. As they mix and cook various foods, make sure they spread the powder/spices all over so that the powder is visible on the counters and food. Invite students to eat the dinner that the mother and daughter have made. Ask the students: What do you see on the food? How did it get there? Where will these germs go after the family eats the food? Tell students that when we act this out, it seems obvious that we should not do these things. However, we all do this every day. Any time that we forget to wash our hands, or go to the bathroom outside, we can get germs in our food and water. Now, let’s see what has happened to the family who ate this food. It’s the next day, and (Pablo) has become very ill. He has bad diarrhea, is vomiting, and his stomach hurts. Remind students that it is very easy to get sick from germs which come from fecal matter. Step 2: How can we properly dispose of waste? The way to prevent fecal-oral contamination is through proper disposal of waste. This means going to the bathroom only in designated areas such as toilet sewer, latrine, or a deep hole where feces can be later buried. Many people do not go to the bathroom in these designated areas; they go to the bathroom in the environment. Even if people go behind bushes or buildings, this practice can be very harmful. Let’s see what happens if everybody in this room were to go to the bathroom anywhere they wanted to. Tell the students to pretend that they have a bowel movement 1 time per day, which makes 7 times in one week. Give students 7 “feces” to place anywhere they want to in the room. After the students have finished, ask them if after a while it was difficult to find a place to go the bathroom. Tell the students to stand back and look at how much fecal matter there is in the classroom. This is what happens when people go to the bathroom wherever they want. Remind them that when the fecal matter is sitting outside, flies can then transfer germs to food and water, and water sources can become contaminated. Step 3: How to prevent fecal-oral diseases The best ways to prevent fecal-oral diseases is by washing our hands, safe stool disposal, protecting water supply, and preventing flies from gaining access to feces. We need to be especially careful when handling food. To protect our water supply, we need to avoid going to the bathroom near water sources such as streams, rivers, wells, and communal taps. We can prevent flies from accessing feces and food by closing the doors to the latrine, burying our feces, and by covering or containing food. We will be talking about handwashing in a future lesson.

Assessment Session name Diabetes Objectives By the end of this lesson, students will: 1. 2. 3. 4. Be able to explain in simple terms, what diabetes is Be able to identify the main symptoms of diabetes Be able to identify at least 5 risk factors for the development of diabetes Be able to identify 5 things that can be done to prevent diabetes Materials Needed Construction paper Chalk Chalkboard 3 signs with insulin, glucose and energy written on them Before you begin Thoughtfully review all material in the lesson plan, focusing especially on the content area to assure you have a firm educational basis for teaching. Think through your teaching strategies and anticipate potential problems or difficulties that may arise. Remember to adapt each session to your audience, keeping in mind their needs and abilities. Prepare all materials: Make signs with insulin, glucose and energy written on them Time chart Learning Activity Step 1: What is diabetes? Step 2: Symptoms of diabetes Step 3: Risk factors and prevention of diabetes Step 4: Application and assessment of learning Total minutes Minutes 20 5 10 15 50 Step 1: What is diabetes? (20 minutes) We our lesson on nutrition we talked about how the food we eat gives us energy and how we need that energy for our bodies to function. Glucose (sugar) is one of the most important things that our bodies need for energy. Glucose is found in many different foods. However, in order for our bodies to use glucose, it has to be broken down by a substance called insulin. This substance (insulin) is necessary to help our bodies make energy out of the foods we eat. If we do not have insulin, or the insulin we do have is not working properly, they our bodies cannot make energy from the glucose. This is a disease known as “diabetes”. Divide the class into 2 groups. One group is “insulin” and the other group is “glucose.” Make a sign that says “energy” and place it in a corner of the room. Tell the glucose to walk around in the middle of the room. Tell the insulin that their task is to catch the glucose and take them to the energy area of the room. Make sure that there are equal numbers so that there is no glucose left in the center of the room. Tell them that we are going to do the game a second time only this time only assign 3 people to the insulin group. The rest are all glucose. Remind the students that each insulin can only take 1 glucose to the energy area. Once all the insulin are in the energy area, point out that there are still lots of glucose in the middle of the room. Also help them to see that there is not very much energy that has been “created.” This is how diabetes works in our bodies. When the body has too few insulin (like in the last game), the glucose cannot be made into energy. The extra glucose in the body can be harmful and cause blindness, nerve damage, heart problems, and death. Step 2: Symptoms of diabetes (5 minutes) Tell the students that the signs of diabetes are as follows: Excessive thirst Frequent urination Weight loss Blurry vision Coma Fatigue Have the students stand up and act out each symptom. Have fun with the actions and exaggerate them. Step 3: Risk factors and prevention of diabetes (10 minutes) There are several things that make it easy for us to get diabetes. Obesity Family history of diabetes Physical inactivity Race (Latinos) Age (older) Poor diet (lots of sugar, not enough vegetables and fruits) As we look at the risk factors for diabetes, which 3 factors do you have control over and which 3 factors do you have no control over? For the 3 factors that you can change, what do you think you could do to prevent diabetes? [Exercise Eat healthily Monitor your weight Don’t consume very much alcohol Avoid foods high in sugar] Step 4: Application and assessment of learning (15 minutes) Have the teacher act as someone who has diabetes, or as a family member of somebody who has diabetes. Tell the students that they are going to act as health workers. Tell them to ask you (the teacher) what your symptoms are. Ask them to tell you what your risk factors are for diabetes and what you can do to prevent it. Content Assessment Cómo usar una bicicleta- con seguridad Usar una bicicleta es buena cosa. Es bien divertido, y pueden llegar más rápido. Pero, a veces no recordamos que puede ser peligroso también. Si no recordamos hacer algunas cosas, biciclar puede ser peligroso. ¿Por qué piensen que la mayoría de las accidentes pasan? Es por que tenemos prisa, y no hagamos las cositas importantes para ser más seguro. Para recordar las tres más importantes, tengo un frase: Conozco el Tráfico y mi Casco 1. Conozca la calle Hay que ver la calle en donde van a biciclar. Por ejemplo, hay que ver donde están los coches, si hay banquetas, o si hay riesgos. Es importante especialmente cuando manejas en una calle nueva. ¿Qué son riesgos? Personas- niños pequeños charcos Animales Árboles Etc. 2. Biciclar con el tráfico Si hagan eso, es más seguro. (¿Por qué?) Si hagan eso, los coches tu pueden ver mejor. Cuando un coche no te puede ver, no sabe a donde vas ni donde estás en la calle. Muchas accidentes se pasa porque el coche no sabía donde estuvo la bicicleta que se pegó. Si bicicletas con el tráfico, significa que estás en el borde (lado) que va donde vas. Por ejemplo, si vas al sur, hay que estar en el borde de la calle que va al sur. 3. Lleva un casco Si quieres prevenir heridos de la cabeza, lleva un casco. La mayoría de heridos de la cabeza que ocurren pasa cuando la persona no llevó casco. Hay que recordar también que el casco te queda bien. Si el casco está demasiado grande, puede caer. Uno demasiado pequeño no sirve tampoco. (Demonstar cómo poner un casco correctamente. Remember: tight straps, centered on head!) Entiendo que es irritante llevar un casco, pero las personas listas llevan cascos. Hace algunas semanas que quería aprender monopatín, pero llevé un casco. (muestrales fotos) Otras cosas: señales Cuándo biciclan, hay señales para decir a dónde vas. (¿Saben estas señales?) Hay que usar el brazo izquierdo Izquierda: pone el brazo en una línea recta Derecho: hace un L con el brazo Para: Hace un L al revés Para recordar estas señales, tengo un juego. (Red Light green Light with the signals) Hay que imaginar que están en sus bicicletas, y quieren llegar aquí, donde estoy. Pero, cuando digo, deben para y hacer la señal que digo. Si no hagan la señal, hay que regresar al principio. El que llega a mí primer, gana. II. Tráfico Cuando andas al lado de la calle, hay cosas recordar bien importantes también. 1. Hay que cruzar en las intersecciones. Si cruzan la calle imprudentemente, es bien peligroso. 2. Cuando cruzan, hay que mirar en las dos direcciones que no hay tráfico. Hay que mirar a la izquierda, al derecho, y a la izquierda otra vez.
