Decay of dead plants and animals by microorganisms returns carbon to the atmosphere as carbon dioxide and mineral ions to the soil. 4.4.1.3 Greenhouse gases in the atmosphere maintain temperatures on Earth high enough to support life. They allow short wavelength radiation from the Sun to pass through the atmosphere to the Earth’s surface but absorb the outgoing long wavelength radiation from the Earth’s surface, causing an increase in temperature. Water vapour, carbon dioxide and methane are greenhouse gases that increase the absorption of outgoing, long wavelength radiation. Describe the greenhouse effect in terms of the interaction of radiation with matter. 1 Ask students to the greenhouse effect (provide them with a range of materials such as (fruit) netting, string, sticky notes, marbles/beads of different sizes, etc). Investigate changing conditions on the effect of temperature in model greenhouses (use plastic bottles). Research methane as a greenhouse gas. How can temperature data be obtained from ice core samples?
