Exploring Elastic Bands
• Introduction

A pile of elastic bands might not look like much, but each one can be a store of energy.

Try the questions in this worksheet to test your knowledge of elastic bands and energy.

• Question 1

What sort of force do you feel when you stretch an elastic band?

a pushing force

a pulling force

• Question 2

Is it harder to stretch a long thin elastic band or a short thick one?

long and thin

short and thick

• Question 3

If you use an elastic band catapult to propel an object what difference does it make how much you stretch the band?

the object will go furthest if you only stretch the band a little

it makes no difference how much you stretch the band

the more you stretch the band the further the object will go

• Question 4

What happens if you try to stretch more than one elastic band at the same time?

the more bands there are the harder it is to stretch them

the more bands there are the easier it gets to stretch them

it doesn't make any difference

• Question 5

You are testing different elastic bands to see which will propel an object furthest. Which THREE of these things do you need to do to make sure it is a fair test?

always use bands of the same colour

always stretch the bands back by the same amount

use the same object every time

always use the same hand to stretch the band

always count to three before releasing the band

always propel the object across the same surface
