Part of the AQA GCSE Combined Science curriculum.
AQA GCSE Combined Science 5.9 Chemistry of the Atmosphere is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the AQA specification (AQA GCSE Combined Science: Trilogy (8464) – 5.9 Chemistry of the atmosphere). It covers the atmosphere today, the Earth's early atmosphere, how oxygen increased and carbon dioxide decreased, greenhouse gases and human activity, climate change and carbon footprints and atmospheric pollutants, then brings it all together with mixed retrieval and exam practice.
There are 20 short steps of about 15 minutes (roughly 5 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Atmosphere, Nitrogen, Early atmosphere, Volcanic activity, Photosynthesis, Algae, Greenhouse gas, Long wavelength radiation, Climate, Climate change, Incomplete combustion and Carbon monoxide.
