Surfaces can be different, ranging from very smooth to very rough.
A comparative test investigation can be carried out to find out how different surfaces can affect how things move.
Scientists make decisions about how to set up and carry out investigations.

All surfaces are only 2-dimensional. All surfaces are made by people (human-made).

Provide many examples, with images, of different types of surface including natural surfaces and 3-dimensional surfaces.

Surface - The surface is the top or outside layer of something.
Rough - Rough surfaces are uneven or bumpy.
Smooth - Smooth surfaces are even.
Comparative test - In a comparative test, the thing that is being changed has labels, such as the types of materials.
Compare - We compare things by looking at what is the same and what is different.
