SCIENCE 6 Quarter 2 By: Sharon P. Estrada Explaining How the Organs of Each Organ System Work Together S6LT-IIab-1 Identifying the Main Parts of Digestive System and Describe the Functions of Each Organs Teaching Strategies: 7 E’s, Group Activity, Question and Answer, Picture clues ELICIT Who can still remember our lesson last meeting? What is skeletal system? What is skeletal system made of? How many bones do humans have? The skeletal system has more than 200 bones. Some bones are fused together, so the number of bones decreases from about 270 at birth to about 206 in adulthood. Are bones alive? Why? How many bones are in the human hand?

ENGAGE Let’s have a short energizer. I am going to show bunch of pictures. These are actually organs and I want you to guess what is it The pictures I presented a while ago has something to do with our lesson for today. What do you EXPLORE GROUP ACTIVITY Remind the learners about the norms / standards to be followed in doing the activity. NORMS / STANDARDS TO BE FOLLOWED IN DOING THE a. Read and understand the instructions properly. b. Cooperate with your group. c. Do not disturb the other group. d. Maintain cleanliness in your workplace. e. Seek the guidance of the teacher if needed. f. Minimize your noise. g. Submit/Report your output on time. • Present the scoring rubric to be used for group activity (Please see attached sheet) • Distribute the materials and the worksheets for the activity. • Let the groups perform the task for 10 minutes. ACTIVITY SHEET: “Which is which?” Learning Target: • At the end of the activity I can identify the main parts of the digestive system and describe the function of each organs Materials: • Diagram of the digestive system Procedure: 1. The sentences below describe the functions of the parts of the digestive system. Read a sentence and identify the part which function is described. 2. The diagram will guide you EXPLAIN GROUP OUTPUT PRESENTATI 1. This part produces pancreatic juices that help digest carbohydrates, fats, and proteins. (Pancreas) 2. This receives the food you eat. The first step in digestion. (mouth) 3. This part has many glands along its walls. These glands release enzymes, hydrochloric acid, and water, which combine to form gastric juice. The enzymes found in the gastric juice breaks down the proteins in the food. (stomach) 4. This is a narrow, coiled tube connected to the stomach where carbohydrates, fats, and proteins are digested. (small intestine) 5. This is the part where waste comes out of the body. (anus) 6. From the mouth, the food passes through the tube serving a passage way of food to the stomach. (esophagus) 7. This produces bile, which helps digest fats. The bile goes into the gall bladder before proceeding into the small intestine. (liver) 8. Undigested food goes into these part then moves out of it as waste. (large intestine) 9. This serves as the passageway of waste from the large intestine (rectum) Group presentation will be rated using the scoring rubrics. ELABORATE Video Presentation Questions: What is digestion? Is the process by which food is change into simpler substances that can be used by the body cells to produce energy. What are the main functions of Digestive System? 1. To break down food into smaller portion 2. To absorb nutrients into blood stream and transfer nutrients to the cells to produce energy. 3. To aid in elimination process of undigested food. What composes the alimentary canal as the major parts of the digestive system? Oral Cavity, Phyrynx , Esophagus, Stomach, Small intestine, Large intestine, Anus How many organs that compose the alimentary canal? Write it in words and figures on the board, please. What are the accessory organs of the Digestive System? teeth, tongue, salivary gland , liver, gall bladder and pancreas What are the two types of digestion? Mechanical and Chemical Digestion Where does digestion begins? mouth Where does final digestion occur? Small intestine What happen to food during chemical digestion? The food particles are broken down into nutrients and other substance that can be absorbed by the body. Why some of the organs of your digestive system are considered excretory organ? They served as passageway of waste out of the body What gland produces saliva? Salivary glands Why do you think you should always chew your food well? to avoid indigestion What are the good eating habits that help proper digestion of food? Show picture of family. How can you help this family to protect their digestive system ? What are the important ideas you have learned from our discussions about digestive system? What is digestion? What are the organs that help digest EVALUATE Encircle the letter of the correct answer. 1. What is the process of breaking up and dissolving food so that it can be taken into the blood to be used by the body? a. Digestion b. Respiration c. Excretion 2. When we eat, all the foods that we take in are not digested; where do you think the undigested food go and stored? a. stomach b. anus c. large intestine 3. In what part of the body digestion is finally completed? a. small intestine b. stomach c. pancreas 4. We use our mouth when we eat our food. Where does digestion begin? a. stomach b. mouth c. anus 5. What part of the body where the waste comes out? a. anus b. rectum c. pancreas EXTEND Study the illustration below. Identify the parts of the digestive system. Label it.
