Enriquez TOPIC CONTENT STANDARD The learners demonstrate an understanding of the one-way flow of energy and the cycling of materials in an ecosystem. LEARNING COMPETENCY Suggest ways to minimize human impact on the environment. LEARNING MATERIALS book, powerpoint presentations, pictures, handouts OBJECTIVES 1. Identify the negative effects of human activities in the ecosystem. 2. Analyze different practices that disrupt a food chain or a food web. 3. Give desirable practices to conserve the environment. Objective 16: Applied a personal philosophy of teaching that is learnercentered (learning objectives) The teacher’s objectives were problem-based. It is the constructivism philosophy of teaching that is learner-centered. The goal of the teacher was to develop motivated and independent learners who are equipped with learning skills in conserving the environment. 1. ELICIT Republic of the Philippines Department of Education REGION III SCHOOLS DIVISION OFFICE OF BATAAN The teacher will lesson about the different present diagrams of dioxide cycle, water cycle, have a review of the cycles in nature. She will oxygen and carbon and nitrogen cycle. The students will identify each diagram. 2. ENGAGE After identifying the different cycle in nature, the teacher will ask the students some of the possible human activities that affect these cycles. The students will predict the consequences of the activities using problemsolution or cause-effect pattern of grammatical signals for idea development, one of their lessons in English. rapid accumulation of CO2- global warming illegal-logging- deforestation greenhouse gas emissions- climate change fertlizer run-off-water pollution air pollution-acid rain 3. EXPLORE Since the students already identified negative effects of human activities in the ecosystem, it is now time for them to analyze different practices that disrupt a food chain or a food web. To start another activity, the teacher will mention one of the themes of geography which is the human-environment interaction that is a part of their lesson in Araling Panlipunan. This will lead her to the introduction of the idea that humans Republic of the Philippines Department of Education REGION III SCHOOLS DIVISION OFFICE OF BATAAN are the top consumers in many food pyramids. This is the reason why human use different methods to increase food production which in return disrupt the food chain or food web. The activity is about farming practices that affect food chain and food web and their corresponding desirable practices to conserve the environment. The class will be divided into six groups. Every group will be assigned with one topic each. The students should analyze the farming practices and their counterparts using the handouts provided by the teacher. MONOCULTURE - GROW A VARIETY OF CROPS HERBICIDES AND INSECTICIDES – BIOLOGICAL CONTROL OF INSECT PESTS CHEMICAL FERTILIZERS – ORGANIC FARMING Objective 16: Applied a personal philosophy of teaching that is learner- centered (instructional activities) Students worked together in small groups to maximize their own and each other’s learning. Cooperative, and collaborative approach are both learner- centered and under the constructivism philosophy of teaching. 4.

The teacher will start to post an illustration of one of the farming practices. The group that is assigned to that farming practice should recognize it since they have the idea of their topic. After identifying the farming practice, each members will share something about it. It will be followed by one of the groups assigned to the corresponsing desirable practice of the farming practice. The members of the group will also share something that they learned from the handouts. The procedure will continue until all the topics are discussed. 5. ELABORATE The teacher will just add additional information about the different farming practices and the desirable practices to conserve the environment since most of idea were already mentioned by the students during their group activity.

Republic of the Philippines Department of Education REGION III SCHOOLS DIVISION OFFICE OF BATAAN Students will also able to apply what they have learned because the teacher will ask them to give ways to conserve the environment aside from those mentioned in the lesson earlier. video link: https://www.youtube.com/watch?v=tNfz0vSHjEU To sum up the lesson, the teacher will call three students who will give a short generalization for each farming practices and their corresponding desirable practice to conserve the environment. 6. EVALUATE Administer a short paper and pencil test. Multiple Choice 1. The following are negative effects of human activities except. a. reforestation b. climate change c. water pollution 2. Monoculture is the cultivation of single crop in large areas. This results to deprivation of food and home of animals. What is the best way to do instead of this? a. use insects to fight other insects to protect plants b. try organic farming c. plant different types of crops 3. Using herbicides and insecticides help farmers to kill unwanted plants but the chemicals in them also destroy beneficial organisms such as soil organisms. To retain this helpful organisms, what can be an alternative to herbicides and insecticides? a. use biological control agents such as predators, parasitioids, pathogens and competitors. b. use biological materials to maintain soil fertility c. practice multiple cropping 4. Some farming practices require large amounts of chemical fertilizers. These fertilizers may run-off to bodies of water causing death of organisms living on them. What is one way to avoid this that has additional benefits to the environment? a. limit the use of fertilizers, plants will still live anyways b. switch to natural fertilizers made from compost and animal manure c. plant crops that do not require lots of fertilizers Republic of the Philippines Department of Education REGION III SCHOOLS DIVISION OFFICE OF BATAAN 5.
