If a material is permeable it will allow liquids and gases to go through it.

A plan is a method that maps out the steps that will be taken during an investigation.

In a comparative test, the thing that is being changed has labels, such as the types of materials.

A variable is something that can be changed, measured or kept the same in an investigation.

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.

Rocks and soils

Which of these materials are soils made from?

Soils have different textures, colours and particle sizes. We call these their ...

Different factories make different types of soils.

Different rocks are weathered and eroded to produce different types of soils.

Different man-made materials make up soils.

Soils have different types of sediment and organic material in them.

Different parts of the country have different types of rock in the soil.

Which of these are the reasons why there are different types of soil?

Which of these things could a soil scientist use to look more closely at the properties of different soil samples?

a fine texture with particles larger than clay but smaller than sand

Match the type of soil to its description.
