Rocks and Soils

This resource, produced by the Royal Society of Chemistry, looks at the properties of rocks and soils. It provides background knowledge to support teachers about the formation of sedimentary, igneous and metamorphic rocks and about erosion and weathering. Investigations look at the properties of rocks and comparison of soil types, including tests for hardness, permeability and porosity. It also contains keys and tests which may be used to identify rocks. Key skills are developed within the practical activities and include: using a magnifying glass to make observations, classifying according to given criteria, carrying out repeated tests fairly, recording results in chart form and using a simple key. Science poems and a concept cartoon are provided to promote discussion and develop understanding.
