How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes.
• What the greenhouse effect is and how human activity changes the energy balance in Earth’s atmosphere. • The potential effects of increased levels of carbon dioxide on the Earth’s climate. • Possible consequences of the increased greenhouse effect.
Modelling the greenhouse effect. In association with Nuffield Foundation. Use this demonstration to illustrate the greenhouse effect and the role of carbon dioxide as a greenhouse gas. Includes kit list and safety instructions.
1) Why is the greenhouse effect important for life on Earth? 2) Name two greenhouse gases. 3) How do greenhouses capture heat?
Worksheet A - Climate change – the evidence. Match the questions to the answers about climate change. 1. What is climate change? 2. What is the ‘greenhouse effect?’. 3. What is the evidence of global warming? 4. How will the weather change? 5. What is the international community doing? A. Sea levels have risen by 10 – 20 cm.
The greenhouse effect is the natural process of the atmosphere letting in some of the energy we receive from the Sun (ultraviolet and visible light) and stopping it being transmitted back out into space (infrared radiation or heat). This makes the Earth warm enough for life.
• How do the physical and digital models of the greenhouse effect reflect what is actually happening on Earth? • Explain greenhouse gases and the basics of climate change in a way that an elementary
