Gravity and Weight

Gravity is a force that pulls everything towards ear Gravity make it seems as if things always fall downwards. Gravity holds us onto earth and stops us fying off into space.

We carried out an experiment using the following material:

*stiff card

*pencil and crayons


*small coins




1. Draw 2 copies of a bear on stiff card ( 10cm from top to bottom and cut them out.

2. Decorate the shapes so that one is the back of the bear and the other is the front.

3. Stick small coins on the back of the paws of one copy and stick the undecorated side together with the drawing side.

4. Balance the bear's nose, hands downwards on the end of a pencil.

We observed if the bear balanced on the pencil.


The bear did balance on the pencil because the weight of the coins made its nose the centre of gravity.
