# Materials - Testing the Properties

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 testing the properties of materials.

At school you have looked at different materials. You have done simple tests on materials. Things we can test, like strength or stretchiness, are called properties. How can you test which material is the strongest or which material is the stretchiest? Can you plan how to test different materials? In this quiz, you are asked about the best ways to test the properties of different materials.
