Fascinating Fact:

Around objects. Rubber bands stretch around boxes, books, and bundles of pens to hold them together.

In KS1 Science, children explore how pushes and pulls can change how things move. Rubber bands are a fun example of elasticity, as they stretch when pulled and return to shape.

Key Terms

Force: A push or a pull that can move something or change its shape.
Elastic: A material that stretches when a force is used and goes back when the force stops.
Rubber Band: A stretchy loop of rubber that shows how elastic materials behave.

Frequently Asked Questions (Click to see answers)

What is elasticity in KS1 science?

Elasticity is when a material can be stretched or squashed by a force and then returns to its original shape when the force is removed.

Why do rubber bands stretch and then go back again?

A rubber band is made from elastic material. When you pull it, the particles move apart. When you let go, they pull back together, so the band returns to its shape.

How can children investigate forces using rubber bands?

Children can gently pull rubber bands with different strengths or use them to fire a small toy. They observe how more force makes more stretch or a longer jump.
