Procedures TEACHER’S ACTIVITY STUDENTS’ ACTIVITY A. Reviewing previous lesson or presenting the new lesson Good morning class! Good morning teacher, good morning classmates, it’s nice to see you again. This morning we will learn a new lesson that will cultivate and foster your mind, but before we properly start our discussion today, let us first play a game. This game is called "Sort It Out." This game is very simple; all you need to do is arrange the jumbled letters in their correct order to reveal the word referring to the picture. You have ten seconds to guess Yes ma’am! each word, and you may raise your hand if you know the answer. Okay, I assume that you are ready. Let us begin with the first picture. LELC What were the words you’ve got from the activity? Yes Fritz? The words were cell, tissue, organ, organ system, organism, population, ecosystem and biosphere. Very good! What do you remember with those picture shown and the words mentioned in the activity? Yes Glenn? The levels of organization which means that living things follows hierarchical order, from simple to complex starting from cell to biosphere. Very good answer! B. Establishing Purpose for the lesson Let’s have another activity. It is called is called 4 PICS ONE WORD. Are you familiar with this game? Yes Ma’am! Very Good! This activity is very simple I will flash a picture and you will guess what word describes the picture presented. Let’s begin! SONTAIPILREH IERDSNF SCETMSAALS Good job class! It seems like you are now ready for our new lesson. For today’s activity, we will be guided with the following objectives: 1. Describe the ecological relationships among living things; 2. Create a pair from the given set of organisms to form an ecological relationships; 3. Reflect the importance of the different ecological relationships found in an ecosystem. I have given you an assignment last meeting. Please submit it from the back to the front. C. Presenting examples/instances of the new lesson In your Edukasyon sa Pagpapakatao o ESP class, you discussed already about “Pagtatamo ng bago at ganap na pakikipag-ugnayan (more mature relations). Class, What is your understanding about the word “relationship”? Students possible answer The state of being connected with others. Close connection between two people. Is relationship only limited to humans? Anyone from the class can answer. "No, ma'am, because animals also exhibit relationships just like us." Very well said Krezen! That is right! Relationship is not limited to humans; animals can also exhibit relationship, as can other creatures living in a certain place, or what we call the ecosystem. Can you still remember what is an ecosystem? “Ecosystem is where living and nonliving thing lives.” That’s correct Lucio! An ecosystem is a community of living and nonliving things that interact and form various relationships. We have various types of relationships with other humans, but that does not mean that relationships can only exist between humans; everything in an ecosystem can have a relationship, which is what we will discuss today. D. Discussing new concepts and practicing new skills #1 Last time you learned that an ecosystem is a Possible responses: community composed of living things and Biotic are those that are living examples nonliving are human and animals. things or what we call or refer to as biotic and abiotic factors. Do you have any Abiotic are those that are non-living idea what biotic and abiotic factor is? examples are water, rocks and soil. There are 3 general categories of biotic factors, these are the producers or the plants, consumers or those that consume plants or other consumers, and lastly decomposers like bacteria, worms, and fungi. Activity: Let’s be pair! Directions: In your respective chair you will find a picture. Put these picture to the upper left of your chest. Find a partner whom you think a relationship can take Possible pair ORCHIDS AND TREE place. Discuss with your chosen partner with what will happen when you pair with each other. Present your work in front. You have 3 minutes to finish your discussion. Then you only have 2 minutes to present your work. Am I clear? HUMAN AND ASCARIS FLOWER AND BEE TIGER AND DEER Two wild dogs fight over a carcass E. Developing mastery Based on your presentation let us answer the following questions: When can you say that the relationship is; ➢ Mutualism? ➢ Commensalism? ➢ Parasitism? ➢ Predation? ➢ Competition? Very good! Students possible answer We can say that the relationship is ➢ Mutualism when two organisms live together and depend on each other or they both benefited with each other ➢ Commensalism when one organism benefits while other is not affected. ➢ Parasitism when one organism benefits and the other is harmed. In this kind of relationship, what do we call to the one who benefits? We call it as a parasite. What do we call to the one who is harmed? We call it a Host. Predation when an organism kills and eats another organism. In this kind of relationship, what do we call to the one who kills and eats another organism? The smaller and weaker animal that the predator kills and eats is called the prey. We call it a predator. We call it a prey. Competition when individuals or populations compete for the same resource, and can occur within or between species Thore are the different ecological relationship found in ecosystem. F. Finding Practical Applications of concepts and skills in daily living Individual organisms live together in an Class, Why do living organisms need to ecosystem and depend on one another. In interact with one another? fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival. How do the interactions among organisms affect their lives and activities? Very good It can affect tier ways on how to survive such as one category of interactions describes the different ways organisms obtain their food and energy. G. Making Generalizations and abstractions about the lesson Ecological relationships describe the The five major types of species interactions: predation, competition, mutualism, interactions between and among commensalism and parasitism. organisms within their environment. What are the five ecological relationships? Can anyone tell me about the 5 ecological relationship? Mutualism describes an interaction that benefits both species. An interaction where one species benefits and the other remains unaffected is known as commensalism. Parasitism is a relationship in which one organism benefits and the other organism is harmed, but not always killed. The organism that benefits is called the parasite, and the one that is harmed is the host. What will happen if there are no ecological relationships? There will be ecological imbalance. In your own opinion, Why are these relationship important in our ecosystem? Ecological relationships are important because it displays the movement of energy in the ecosystem. Ecological relationship is very important in our ecosystem. Every part has its own duties in maintaining the natural flow of the ecosystem. If there are part or one that become endangered, there is a possibility that all the remaining parts would be in danger. H. Evaluating Learning A worksheet will be given to the students for their evaluation. (Pls. See attached worksheet and scoring rubric) I. Additional Activities Assignment. Write it on 1 whole sheet of paper. 1. Outline the effects of the following pair of organisms to each other. Tell the ecological relationship existing between the two. ✓ Algae & Lichen ✓ Ants & Aphids ✓ Termite & Woods ✓ Man & Lice ✓ Dog & Tapeworm ✓ Orchid & Tree 2. What is the effect of changes in one population on other population in the ecosystem? That’s all for today Good bye, class V. Remarks VI Reflection A.
