I. Conceptual Understanding
1. What is climate?
• Climate refers to the weather conditions such as temperature and rainfall prevailing in an area over a long period.
2. What are the effects we face due to climate change?
• The effects of climate change include untimely rainfall, droughts, floods, melting of ice, rising sea levels, cyclones, tsunamis, and forest fires. It also impacts food production and causes the death of aquatic plants and animals.
3. What are the reasons for climate change?
• The main reasons for climate change are deforestation, pollution from industries and vehicles, overuse of natural resources, burning waste, and the excessive use of plastic and harmful chemicals.
II. Questioning and Hypothesis
4. In your village, people are suffering from drought. Can you guess the reasons?
• Drought could be due to a lack of rainfall caused by deforestation, climate change, overuse of groundwater, pollution, and improper agricultural practices.
III. Experiments and Field Observations
5. Observe the process used for disposing of garbage at your home and make a report.
• At home, garbage is segregated into wet waste (food leftovers, peels) and dry waste (plastic, paper). Wet waste is composted to make manure, while dry waste is sent for recycling or discarded. However, in some cases, improper disposal, such as burning or dumping, causes pollution.
IV. Information Skills and Projects
6. Collect information about students who are using steel water bottles instead of plastic water bottles.
• A survey at school shows that 60% of students use plastic bottles, while 40% have switched to steel bottles. The latter group prefers steel bottles for their durability, safety, and eco-friendliness, reducing plastic pollution.
V. Drawing and Model Making
7. Make a pen stand, flower vase, etc., by using a plastic water bottle.
• This activity involves cutting and decorating plastic bottles creatively to reuse them as pen stands, vases, or storage containers, promoting recycling.
VI. Appreciation
8. Prepare some slogans on ‘Save Environment.’
• “Plant Trees, Save Lives.”
• “Reduce, Reuse, Recycle.”
• “Say No to Plastic, Yes to Nature.”
• “Save Water, Save the Planet.”
• “Act Now, Save Tomorrow.”
