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.

Adam wants to find the stretchiest material.

Adam has a piece of string, a piece of wool, a piece of cotton, and a rubber band. They are all 10 cm long.

Adam ties a 50 gram weight to each one.
