LEARNING PLAN
Introduction
1. Let the pupils refer to the picture on page 44 of the worktext. Ask: What does the picture tell you? Why do people need to protect the plants and other resources?
2. To hook the interest of the pupils, let them listen to the story entitled “The Earth Book.” The story, as told by its author Todd Parr, can be accessed from https://www.youtube.com/watch?v=aXnWUS_K0XQ. Ask the pupils to share the important insights that they gained from the story. Ask them the following questions:
• Why do we need to care for the earth?
• What environmental concerns that are happening on earth do you know of?
• Can a young person like you contribute in caring for the earth? How?
3. Pose the essential questions. Tell the pupils that they should be able to answer these questions at the end of the lesson. Introduce the topics to be discussed and the tasks that should be accomplished as they tackle the lesson.

Learning Experiences/Lesson Development
Proper Waste Management
1. Access pupils’ prior knowledge. Write on the board the five Rs of waste management (reduce, reuse, recycle, recover, and repair). Let the pupils identify the words that they already know and understand.
2. Let the pupils read the text about proper waste management on pages 46 to 49 of the worktext. Engage them in a discussion about the five Rs of waste management. Ask them to give examples of the things that they can do to reduce, reuse, recycle, recover, and repair materials, aside from those given in the worktext.
3. Let the pupils perform Examine activities 1 and 2 on pages 52 to 57 of the worktext. These activities will give the pupils opportunities to turn trash into something useful. Let the pupils show their output in class. Discuss their answers to the guide questions.
4. Assign the pupils to visit the website provided in Technology Today on page 52 of the worktext. Encourage them to explore the site and play the games and interactive activities. In the next meeting, call on pupils to share what they learned from the site. Lead the pupils in realizing the importance of reducing and recycling wastes.
5. Integrate values in the discussion. Show the pupils examples of nonbiodegradable materials like plastic containers, Styrofoam cups, and others. Briefly explain that plastic and Styrofoam materials take a very long time to decompose. Ask: What do you think will happen if people will continue throwing these kinds of materials? How can young pupils like you help in solving environmental problem on waste in your community? Discuss their answers. Lead them to make a commitment to apply the five Rs of waste management. Let them do the Journal Writing activity on page 52 of the worktext.

Activity 1
1. The activity promotes recovering and reusing of materials. The bottles can be recovered from trash and were reused by making it into a feeder.
2. Other materials that can be made into feeders are shoe boxes, old milk cartons, or big cooking oil cans.
Conclusion
I learned that soda bottles can be reused. An example of reusing a soda bottle is turning it into a bird feeder.
