I know that there are different sorts of rocks and can describe basic properties from observations.

I know rocks have been around for a long time.

I can name the three types of rock.

Rock Types

Looking for Rock Types

I can name the three types of rock and give at least one example of each;

I can describe some characteristics of each rock type;

I can explain that high temperature and pressure can change existing rocks into different types of rocks. 

A Rock Song!

I can describe and explain how sediment becomes sedimentary rock;

I can describe the conditions under which metamorphic rock is formed and how igneous rocks crystallise from magma;

I can describe some distinctive features of igneous, sedimentary and metamorphic rocks and use these to distinguish between the rock types. 

I can explain how igneous sedimentary rocks are formed and the time scale involved.

I can relate crystal size to rate of cooling. Interpret geological diagrams.

I understand the rock cycle.

I can explain in terms of the particle model how different rates of cooling lead to different crystal sizes;

I can bring together physical and chemical processes to explain the formation of different rock types and the rock cycle;
