Earth and Atmosphere
This list covers a wide range of connected topics linked to environmental aspects of chemistry at key stage 4.
The resources cover the composition and evolution of the Earth's atmosphere since the Earth was formed, and present day atmospheric pollution such as acid rain and particulates (POMs or particulate organic matter). The source of such pollutants in the combustion of fossil fuels, and the potential consequences to the environment and to health are also included here.
Students need to understand the greenhouse effect and its consequences in terms of global warming and climate change. Students often confuse the greenhouse effect and global warming and assume they are the same thing. Methods of reducing the amount of carbon dioxide in the atmosphere are also included.
These resources also look at how drinking water is obtained from surface and ground water, including filtration to remove particles and sterilisation to kill microorganisms, desalination and the treatment of waste water and sewage
Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or other recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment.
