You are going to investigate the strength of different materials. Strength means how much an object resists being damaged or broken.

In your experiment, you will need to think of one way of damaging the different pieces of paper. You will then need to record how well each piece of paper coped when you damaged it.

For example, you might want to tear each piece, and record (by giving each piece of paper a score) how easy it was to tear.

You could also poke the paper with an object and see if a hole is made.

If you have another idea, share it with your group and decide which might be the best way of testing the strength.

Remember, you must work out some way of recording how easy or hard it was to damage the paper, so that we can compare results later.
