Science Buddies: "Ask an Expert"

Ahh please help! >.<
For my French IB class, I'm supposed to make an experiment with 2 different types of science (ex. chemistry, biology, environmental sciences, physics etc.), and the topic is durability. I can't think of anything!

What do you mean by durability? Are there any other requirements?
You could do durability of pieces of paper by seeing how much weight a single sheet up paper can hold before ripping?

You could also do durability of how long it takes to burn or crush something?
