Thanks for the questions. The ball bounces higher on the carper because carpet are more “bouncy” that a hard floor, and they add their bounciness to the ball. If the ball breaks apart when you bounce it, you should use less cornstarch and it should stick together more – also make sure you mix it up really well. Have fun!

We have a couple of questions:
1. why does the ball bounce better on carpet than a hard surface?
2. why does the ball shatter on a hard surface? Is it to do with the polymers, if so what/why?

Your conclusion would be based on your hypothesis (what you thought would happen) If, for example) your hypothesis was that the ball would bounce, and it did not, your conclusion would be that the steps you followed did not make a ball that bounces. I hope that helps a bit.

Im doing a project on this lab its hard to make a conclusion on this but when my science partners tried this it didn’t bounce at all. So, what should i say as my conclusion on the data???
