I know that there are different sorts of rocks and can describe basic properties from observations.  Know rocks have been around for a long time.

I know that rocks have different names e.g. igneous, sedimentary.  Rocks are weathered – be able to describe its effects.

I can describe rock specimens in terms of texture and relate this to properties such as porosity. 

I can describe and explain the processes by which layers of sediments are produced.
 

I know that rain can be acidic and this weathers rock.

I know that water expands when frozen and understands that this causes weathering. 

I know how Sedimentary rocks are formed and the time scale involved.

Fossils Song

I can describe rock specimens and recognise that different rocks have different textures;

I can describe some effects of weathering and recognise sedimentary layers.

I can describe chemical processes involved – word equation for acid + carbonate.

I can relate processes of chemical weathering to the reactions of particular grains with acids;

I can relate sedimentary layers to the processes by which they were produced.

I can describe chemical processes involved - use symbol equations for acid + carbonate.
