Help! Need Science Fair ideas **UPDATE**

So my 9.5 year old and his friend decided they want to be apart of the science fair. They are both into sports, amusement parks, water parks, etc.
We are trying to think of something that would be interesting to them with any of those ideas.
Will look on pintrist too or google.

Thanks!

This is our first year doing it so it's new to me.


**UPDATE**
Thanks for the awesome ideas! So my son and his friend came home from school yesterday saying they are going to make milk into plastic bc the teacher helped them with some ideas. LOL
That was what they chose. Oh well, I have next year.

Last year, my son measured trajectory at different angles to see which angle shot a nerf gun at the greatest length.
This year, he's producing energy.
Sounds like he is interested in physics so I would google those ideas.
You can also measure the "bounce" in a ball at different temps and see if that makes a difference.

Maybe something with the slope of the waterslides and the speed of descent?

Last year, some boys in that age range made paper airplanes out of different types of paper to see which one flew the farthest.
