Science Ideas

I. Objectives:
    
      With the use of the video presentation and varied activities, the second year  high school students with at least 85% accuracy should be able to do the following:

•   a. explain Global Warming in different perspectives
•   b. demonstrate some ways on how to prevent or to lessen the effects of Global Warming
•   c. appreciate the role of Environmental Programs in preventing or at least lessening the effects of Global Warming

II. Subject Matter:
  
     Concept: Environmental Issue
     Topic: Global Warming
     Skills to be developed: critical thinking, debating or reasoning, researching
     Values to be developed: awareness, sense of responsibility, teamwork


III. Instructional Materials:
     
     Textbook: Añes, Myrna, Lee, Sergio, LECTURE NOTES IN ENVIRONMENTAL SCIENCE: THE ECONOMY OF NATURE, pp. 150-157
     Scaffolds: video presentation downloaded from Youtube entitled "Global Warming: A Point of No Return & "What is Global Warming", comic's strips entitled "The Day the Earth Stood still or Crisis, what crisis?


IV. Procedure:
  A. Opening Activity

1. The teacher will ask a motivating question, "How do you find the summer vacation?" (The expected answer from the majority of the students will be "The weather is so hot"). "How can you describe the temperature this year than the previous years?" (Varied answer is expected.)
2. The teacher will now show a video presentation downloaded from Youtube.
3. After the presentations, the student will now group into four groups. They are going to role play some ways on how to prevent or lessen the effects of global warming.
4. The teacher will be the one to critic their role play presentation.
5. The best role play will be given 20pts. Each member of the group and the rest will be 15pts.

  B. Developmental Activities    
      
   1. Analysis

• Physical: What will happen to the physical condition of the earth if global warming continues?
• Biological: How does global warming affects the lives of the people as well as the other living things?
• Economic: Was the world's food supply and the prices of other products has been affected by the global warming? In what way?
• Social: What will you do to minimize the effects of global warming? How are you going to influence others to minimize the overpopulation of harmful greenhouse gases?
• Political: What government agencies do to help prevent the effects of global warming? What Environmental Programs you know that concerns with the prevention of global warming?
• Communicative: How did government as well as others implement it?

   2. Abstraction:

• The students will be group into four groups. Each group will be given a comic strip related to the topic global warming.
• They are going to interpret the message of the comics. Then they are going to answer the follow-up questions.
• The answers will be written in a one whole sheet of intermediate pad.

    Questions:

1. What is the message of the story?
2. What is the main problem in the comics?
3. Why do people in the planet Earth are not aware of their Environmental problem?
4. What is the role of the Martians (aliens) in the comics?
5. What behavior does the people on Earth shows?
6. What statement in the comics do you find relevant? Why?

C. Concluding Activity

1. Application (DEBATE)

• The students are going to group into 2 groups (TEAM YES and TEAM NO). Each group will be given 10 mins for their speeches.

         "WITHIN OUR LIFETIME, CAN WE SIGNIFICANTLY SLOW DOWN THE WARMING OF THE EARTH?

• Each team will be given 20pts for their oral recitation.

    2. Valuing

•  The class will now again form into four groups. Each group will create an "Environmental Program" of their own.
• They will state the Environmental Program's goal, mission and vision.   
• After planning, they will present to the class of what their environmental program all about and how they are going to implement it.

V. Evaluation:
     Directions: Write your answer in a one whole sheet of paper.

1. Draw an illustration on how global warming occurs.
2. Make a schematic diagram showing the causes and effects of global warming.

VI. Assignment: (In a 1/2 crosswise sheet of paper)

1. Research on some areas here in Cebu that is most likely can be affected with the increase of sea level?
