topic 10: human influence on the environment
Section 4: Ecology and the environment d) Human influences on the environment
4.11 understand the biological consequences of pollution of air by sulphur dioxide and by carbon monoxide
4.12 understand that water vapour, carbon dioxide, nitrous oxide, methane and CFCs are greenhouse gases
4.13 understand how human activities contribute to greenhouse gases
4.14 understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences
4.15 understand the biological consequences of pollution of water by sewage, including increases in the number of micro-organisms causing depletion of oxygen
4.16 understand that eutrophication can result from leached minerals from fertiliser
4.17 understand the effects of deforestation, including leaching, soil erosion, disturbance of the water cycle and of the balance in atmospheric oxygen and carbon dioxide.
Section 5: Use of biological resources a) Food production b) Selective breeding
5.1 describe how glasshouses and polythene tunnels can be used to increase the yield of certain crops
5.2 understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses
5.3 understand the use of fertiliser to increase crop yield
5.4 understand the reasons for pest control and the advantages and disadvantages of using pesticides and biological control with crop plants
5.9 explain the methods which are used to farm large numbers of fish to provide a source of protein, including maintenance of water quality, control of intraspecific and interspecific predation, control of disease, removal of waste
products, quality and frequency of feeding and the use of selective breeding.

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. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?
