That is a reasonable hypothesis. The rest of the write-up should flow from this...

Explain why you think the hypothesis should be true, i.e. have you done any research on this that suggests this hypothesis?

What method could you use to investigate it? Discuss this with your peers (since planning will be low control).

What can go wrong with your plan and harm someone? How can you try to prevent this happening, and/or if you can't stop it, how can you minimise the risk of injury?

Then do it and see where the data take you.

Do you have a supply of materials made from short chain polymers (candle wax) and long chain polymers (polythene)?

Do you know what 'stronger' means?
