Materials - Rough And Smooth

This quiz addresses the requirements of the National Curriculum KS1 Science for children aged 5 and 6 in years 1 and 2. Specifically this quiz is aimed at the section dealing with the texture of materials, for example rough and smooth.

Have you ever tried running your hand over a brick wall? It is rough. But the glass in a mirror is really smooth. What is the difference between rough and smooth? Different materials feel very different. Some are soft to the touch. Others are hard and sharp - some are so sharp they could cut you. How materials feel is called their texture. Let’s find out a bit more about the texture of materials.
