How geologists work

In this Rocks and soil unit, pupils learn to describe in simple terms how fossils are formed. In the Evolution and inheritance unit, pupils will build on this knowledge to recognise that things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago.

In the Uses of everyday materials unit, pupils learnt to identify and compare the suitability of materials, including rock. In this Rocks and soils unit, pupils will build on this knowledge to compare and group different kinds of rocks on the basis of their appearance and simple physical properties.

This unit covers comparing and grouping rocks based on appearance and physical properties, understanding fossil formation, and recognising that soils are made from rocks and organic matter. It involves setting up practical enquiries, making observations, and using evidence to answer questions.
