Opening Prayer Let us all stand to feel the presence of the (The student lead the prayer) Lord. Kim, kindly lead us a prayer. 2. Customary Greeting Good morning class! Good morning ma’am Before you take your seat see to it that your chairs are properly align and pick up the thrashes under your chairs. If you’re done you may now silently take your seats. 3. Checking of attendance Secretary are all of you are present today? Yes ma’am General Rule: 1.Observe silence once the discussion started. This means switches off or silent all your phones. 2.Just raise your right hand if you know the answer, do not shout it. 3.Be cooperative in doing any activity, work collaboratively and follow procedures religiously. Is that clear class? Yes ma’am B. Review Last meeting, we talked about symbiotic relationship and its different types. So there are 5 types of symbiotic relationship, give one types of it? Yes, Jane. One of the symbiotic relationships is Mutualism; it is a symbiotic relationship where both organisms are benefited from each other. Give me one another types of symbiotic Another type of symbiotic relationships is relationship. Yes, Cris. Commensalism; it is where the organism is being benefited while the other one is unharmed. What else? Yes, Jake. Who can give another one? Yes, Mike. Precisely! Now how about the last one wherein organisms compete or fight for survival. Yes, Rudy. Parasitism; it is where the organism is benefited while the other one is being harmed. The parasite is sucking its nutrient to feed from the host. Predation ma’am; It is where the organism serves as a food to the other organism, the predator hunts for its prey, which serves as a food. Competition ma’am. Very good. I am glad that you remember our past lesson. C. Motivation Before we start our activity let me first group you into 3 (The teacher divide the student) Our activity is entitled “Guess Me What” Here is the mechanics of the game Can you please read. Yes, James? Mechanics: 1. The chosen representative of the group will pick inside the box a paper with a word written on it. 2. The representative will act the word that he/she picked. (the representative must not say any word/s, anyone caught speaking while acting will be having a deduction of two points) 3. The remaining members of the group will be the ones to guess what their team mate is acting (you may pass if you cannot guess the word at hand and pick another one) 4. Within 30 seconds, the group with the highest point will be given a reward! D. Presentation of the lesson In order to unlock our topic for today, let’s have another activity entitled “Solve me, I’m broken” Cha can you please read the mechanics of the game/activity. Mechanics: 1. Each group have an envelope 2. Inside the envelope there must be a puzzle cut-out 3. Paste the puzzle on the bond paper 4. Each group must solve the puzzle 5. You will be doing this activity in 2 minutes 6. After solving the puzzle, see at the back you will see numbers paste the output base on the number. Are the mechanics clear to you class? Yes ma’am (The teacher go around to check the output of the students) (The students work on their task to solve the puzzle) So, group 1 what does the picture or the puzzle wants to portray it’s a ______? Food ma’am Very good! How about the group 2? Addition sign ma’am which is plus Very good! Group 3? It’s a chain ma’am So, if we combine the two words which is food and chain what would it be? Yes, Vane. Food Chain ma’am. Very good! You are all wonderful! Give yourselves a clap! E. Discussion Let’s watch a simple video on food chain be a good listener and viewer so that you will understands the concept and take note of the important details Is that clear class? Based on the video that you’ve watch what is a food chain? Yes, Julia. Yes, ma’am Food chain is a sequence of organisms that feed on each other and it is a pathway that represents the exchange of energy from one organism to another. Precisely! What does food chain show? Yes, Joy. Very good! What is the source of energy? Its show where energy goes ma’am. Yes, Mark. The sun ma’am That’s right! A food chain always starts with the sun. How about the organisms that make their food from the sunlight.? They are the plants ma’am Very good! And they are also called as _____? Excellent! Producers ma’am If the plants are capable of utilizing sunlight to produce their food, other organisms, on the other hand, feeds on other organisms. What letter C, are they called? Now I will show you the trophic level (The teacher show the picture of the trophic level) Consumers ma’am (The teacher discuss the trophic level) Based on the picture what is the biggest part on the pyramid? Yes, Mel. Why do you think that the producers have the biggest part? That’s right! Producers ma’am Because it can create its own food from the main source of energy through the process of photosynthesis. Let’s have an example of a food chain (The teacher give an example of food chain) Now it your turn to give an example of food chain Yes, Jayson. (The student give his/her answer) Excellent! You’re doing good job! F. Activity Proper Now, we’ll be having an activity which is entitled “Construct chaining”. In my (Representative of every group get the envelope) hands are envelopes containing pictures. Representatives from each group please get your envelope now. Do all the groups have their envelopes? Yes ma’am Who would like to read the mechanics for this activity? Yes, Roy. Mechanics: Thank you Now class, do you have questions or violent reactions regarding the activity and its mechanics? (After 3 minutes every group present their output) 1. Construct a food chain using the pictures inside the envelope. 2. Explain your work showing the transfer of energy from the food chain you have constructed. 3. You will be given 3 minutes to finish the task and present your outputs afterwards. None ma’am G. Generalization Again class, what science concept did we learned today? Yes, Mica. Very good! It’s all about food chain ma’am! And what comprises a food chain? Yes, Love. Excellent! So, Love stated the consumers and their orders, now who could give me the other names of consumers? Very good! a food chain is composed of; 1. The sun which is the main source of energy 2. The producers or the plants who makes their own food using sunlight 3. The consumers which are categorized into: first order consumers, the one that eats the producers, the second order consumers which eats the first order consumer, and the third order consumer, which basically eats the second order consumer. 4. And the decomposers which feeds on the decaying organisms. The consumers are also called as: 1. Herbivores- and they eat plants only 2. Carnivores- who feeds on meat only 3. Omnivores- which eats both plants and animals The fact that you guys can state the summary of our lesson means that you understood the lesson very well. H. Application I have pictures of organisms here. Now, I will raise the pictures one at a time and your task is: 1. to tell me what do you see on the picture 2. to tell me whether it is a producer, an herbivore, carnivore, omnivore, or a decomposer. You have to raise your hand if you want to answer. Understood class? (The teacher will raise the picture one at a time) Wow, you are good at classifying organisms now, that’s a proof that you are listening and participating carefully in our discussion. Yes, ma’am (The students answer) I. Valuing So I have here a quotation, kindly read it class. “No man is an Island” How can you relate this quotation with our topic? Yes, Joyce. Very well! We need one another in order to live. We must always remember to value the life of every organism, from the tiniest bacteria to the biggest blue whale and from the smallest seed of mustard to the tallest plant. Because everyone is included in the circle of life! (The student share their ideas) J. Evaluation For today’s lesson, I will give you a worksheet to work with. You will be doing this for 5 minutes. (The student do the task ask by the teacher) A. From the illustration above, identify the following. Main Source of Energy: _______ Producer:________ First Order Consumer: ______________ Second Order Consumer: _________ Third Order Consumer: ___________ B. List down the organisms found in your community. Classify the organisms according to the following categories by putting a check on their classification. (Group 1 present your output) (Group 2 present your output) (Group 3 present your output) (Group 1 present their output) (Group 2 present their output) (Group 3 present their output) Let’s clap for ourselves for accomplishing the task. Now pass your worksheets forward. K. Assignment Everyone, kindly bring out your notebooks and copy your assignment. That’s all for today class Good bye! 1. What is food web? 2. Give example of food web Good bye ma’am.
