Changing shape: plan and do

In this Uses of everyday materials unit, pupils learnt that the shapes of some solid materials can be changed in different ways. In the Introduction to states of matter and changing states unit, they will build on this knowledge to observe that some materials change state when they are heated or cooled

In the Everyday materials unit, pupils learnt to identify and name a variety of everyday materials. In this Uses of everyday materials unit, pupils will build on this knowledge to compare the suitability of everyday materials for particular uses

This unit explores identifying and comparing the suitability of everyday materials like wood, metal, and plastic for specific uses. It examines how solid objects' shapes can change by squashing, bending, twisting, and stretching. The focus is on simple tests, and using data to answer questions.

Uses of everyday materials

Physical activity and equipment requiring safe use

How can we find out which materials can change shape?

Which of these shows a material whose shape cannot be changed by squashing, bending, twisting or stretching?

It always stays in the shape it has changed to.

It can sometimes go back to its original shape.

What happens when a material changes shape?

Which of these materials go back to their original shape after they have been stretched?

Push on them to make them thinner and flatter.

Which of these photographs shows dough that has been bent?

True or false? When we twist something, we hold each end and turn it in opposite directions.

When we stretch something, we pull it to make it {{}}.

Which of these materials can be stretched?
