Kiling National High School Tanauan, Leyte Semi-detailed Lesson Plan in Science 7 Student Teacher: Jim Albert E. Morot Date: February 08, 2017 Grade & Section: 7- Diamond Time: I. Objective: * Describe the features of each layer of the atmosphere. * Compare the features of the four layers. KBI: Appreciate the importance of the atmosphere and the layers of the atmosphere. II. Subject Matter: A. Topic: Interactions in the atmosphere B. Sub-topic: Solar energy and the atmosphere C. References: K to 12 curriculum guide, Science 7: pp. 135 Learner’s material in Science 7: Unit 4, module 2: pp. 239 D. Materials: Meta strips, chalk, laptop, projector, cardboard, brown envelop III. Procedure: A. Preliminary Lesson: 1. Review: “Fact or bluff” The teacher will ask questions about their previous lesson. The students will answer the questions and raise their cardboards with their answer. Questions: 1. A watershed is an artificial lake, storage, pond created using a dam to store water. (Bluff) 2. Recycling plastics and papers is one example of conserving our natural resources. (Fact) 3. A reservoir is one example of natural resources. (Bluff) 4. A waterfalls is an area of land where all of the water that falls in it drains off of it goes to a common outlet. (Bluff)

5. Coal is an example of renewable resources. (Bluff)

2. Motivation: * The class will be divided into five (5) groups. The teacher will give each group a “word puzzle”. The students will find and encircle the words in the puzzle. The group that will first to finish the activity will win the game. 3. Presentation: B. Lesson Proper: 1. Activity: What is the basis for dividing Earth’s atmosphere into layers? (Group activity: Each group will perform the activity) Criteria Teamwork Accuracy Time management Behavior Total

2. Analysis: 1. What are the four layers of the atmosphere? * The four layers of the atmosphere are troposphere, stratosphere, mesosphere, and thermosphere. 2. What is the estimated height of each layer? * The troposphere is 10 to 40 km above the earth’s surface, stratosphere is 50 km, mesosphere is 80 km and thermosphere is 110 km above the earth’s surface. 3. In which layers is temperature increasing with increasing altitude? * The layer in which the temperature increase with increasing altitude are the stratosphere and thermosphere 4. In which layers is temperature decreasing with increasing altitude? * The layer in which the temperature decrease with increasing altitude are the troposphere and mesosphere. 3. Abstraction: * What are the four layers of the atmosphere? * The four layers of the atmosphere are troposphere, stratosphere, mesosphere, and thermosphere.

* What is the difference between the each layer of the atmosphere? * The difference between each layer of the atmosphere is that each layer plays a different role in protecting the earth and all inhabitants in it. 4. Application: * Imagine the atmosphere and the layers of the atmosphere, is atmosphere and the layers of the atmosphere important for our daily lives survival? Imagine the world without our atmosphere, what can you infer from it? IV. Evaluation: Direction: Read each questions carefully and write only the letter of the correct answer. Do it in a one fourth sheet of paper. 1. Earth’s atmosphere is composed of what gases? a. Helium and argon c. Nitrogen and oxygen b. Carbon dioxide and argon d. Oxygen only 2. What do you call the boundaries between troposphere and stratosphere? a. Stratopause c. thermopause b. mesopause d. tropopause 3. What would be the result if meteors and rock fragments will NOT burn up in the mesosphere? a. The earth’s surface will have many holes as big a football field. b. There will be a global extinction. c. The planet will eventually explode. d. All of the above. 4. Which of the following BEST explains Earth’s atmosphere? a. An invisible barrier that prevents water from escaping the earth. b. The layer that is closest to the sun. c. A layer of gases surrounding a planet or other material body. d. None of these. 5. In which layer of Earth’s atmosphere is the ozone layer located? a. thermosphere c. troposphere b. mesosphere d. stratosphere

IV. ASSIGNMENT: 1. What is greenhouse effect? 2. Give at least 5 events that can cause global warming or climate change.
