This unit builds on
unit 3D 'Rocks and soils' in the key stage 2 scheme of work.
The two units about Earth science draw on work about pH in unit 7E 'Acids and alkalis', work on evaporation in unit 7H 'Solutions', work on mixtures in unit 8F 'Compounds and mixtures' and work on changes of state in unit 8I 'Heating and cooling'.
This unit relates to unit 2 'The restless earth - earthquakes and volcanoes', unit 7 'Rivers - a fieldwork approach' and unit 8 'Coastal environments' in the geography scheme of work.
The unit provides a foundation for work on the rock cycle in unit 8H 'The rock cycle'. Ideas about weathering are revisited in unit 9G 'Environmental chemistry'. Together with unit 8H 'The rock cycle', this unit lays the foundation for work in key stage 4 on rock formation and deformation and on processes involving tectonic plates.
