Lesson Content
Change In Our Climate: Global Warming
Global warming refers to the gradual increase in the Earth’s average temperature due to the buildup of greenhouse gases like carbon dioxide in the atmosphere. This means that human activities, such as burning fossil fuels and deforestation, are causing more heat to be trapped in the Earth’s atmosphere, leading to various environmental changes.
Causes of global warming
- Burning of fossil fuels like coal, oil, and gas.
- Deforestation, which reduces the number of trees that absorb carbon dioxide.
- Industrial processes that release large amounts of greenhouse gases.
- Agricultural practices that produce methane, such as rice paddies.
- Increased use of motor vehicles leading to higher emissions.
Ways to Control global warming
- Planting more trees to absorb carbon dioxide.
- Reducing the use of fossil fuels by switching to renewable energy sources.
- Recycling materials to reduce waste and pollution.
- Conserving energy by using energy-efficient appliances.
- Promoting public transportation and reducing car usage.
Effects of global warming
- Rising sea levels due to melting polar ice caps.
- More frequent and severe weather events like hurricanes and droughts.
- Loss of biodiversity as animals lose their natural habitats.
- Increased health problems related to heat and pollution.
- Food shortages due to changes in agricultural production.
Lesson Evaluation:
To evaluate the learning, the teacher asks pupils to:
- What is global warming, and what causes it?
- List five ways to control global warming.
- Describe three effects of global warming on the environment.
- How can planting more trees help in controlling global warming?
- Discuss with your partner how global warming might affect your community in the future.
