# KS1 Science Quiz - Forces - Changing Shape (Questions)

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 forces and how they change the shape of materials.

What happens when you apply force to an object? You already know that some materials can change shape but bounce back again - springs, rubber bands and balloons. But other materials stay in their new shape. If you push or pull on dough or modelling clay and change its shape, what happens? It stays in the new shape. You can use force to mould dough and clay. It is good fun. It is also good science.
