Module Topics Soil-Net links
Module C1 Radiation and Life  
P2.3.1 recall that the Earth is surrounded by an atmosphere which allows light radiated from the Sun to pass through; Global cycles

Oxygen cycle

Nitrogen cycle

Carbon cycle
P2.3.2 recall that this radiation:
provides the energy for photosynthesis; warms the Earth's surface;
Soils, plants and food
P2.3.3 recall that photosynthesis removes carbon dioxide from the atmosphere and adds oxygen, and that this reverses the effect of respiration Carbon cycle

Climate change
P2.3.4 understand that the Earth emits electromagnetic radiation that is absorbed by some gases in the atmosphere, so keeping the Earth warmer than it would otherwise be. This is called the greenhouse effect; Global cycles

Climate change - future concerns
P2.3.5 understand that the ozone layer absorbs ultraviolet radiation, producing reversible chemical changes in that part of the atmosphere; Oxygen cycle

Module P2.4 What is the evidence for global warming, why might it be occurring, and how serious a threat is it? Climate change

Climate change threats

Climate change - future concerns
P2.4.1 recall that one of the greenhouse gases in the Earth's atmosphere is carbon dioxide, present in small amounts; Carbon cycle

P2.4.2 recall that other greenhouse gases include methane, present in trace amounts, and water vapour: Carbon cycle

P2.4.3 interpret simple diagrams representing the carbon cycle; Carbon cycle
P2.4.4 use the carbon cycle to explain:
  • why for thousands of years the amount of carbon dioxide in the Earth's atmosphere was approximately constant;
  • how decomposers play an important part in the recycling of carbon;
  • that during the past two hundred years, the amount of carbon dioxide in the atmosphere has been steadily rising;
  • that the rise in atmospheric carbon dioxide is largely the result of:


burning increased amounts of fossil fuels as an energy source;
burning forests to clear land;

P2.4.5 understand that computer climate models provide evidence that human activities are causing global warming; Climate change threats

Climate change - future concerns
P2.4.6 understand that global warming could result in:
climate change and how this could make it impossible to continue growing some food crops in particular regions;
extreme weather conditions in some regions;
rising sea levels, due to melting continental ice and expansion of water in the oceans, which would cause flooding of low-lying land.

Module P3 Radioactive materials  
P3.1.2 understand that radioactive elements are naturally found in the environment, emitting background radiation; Soils and health

Soils and pollution
P3.2.7 understand that radioactive materials expose people to risk by irradiation and contamination; Soils and pollution
P3.2.8 recall that we are irradiated and contaminated all the time and name some sources of this background radiation; Soils and pollution

Waste disposal
P3.3.6 recall that power stations which burn carbon fuels will produce carbon dioxide Climate change
