Q1: What are two examples of springy materials?

[Answer]

Springy materials will change shape when you pull or push them. But they will go back to what they were like at the start as soon as you let them go.

Springy materials have a sort of 'memory'. They 'know' what shape they are and they don't like changing to a new shape.

Another word for springy is elastic – such as in elastic band.
