Anyone have ideas on a good.. But elementary high school ap level physics experiment?

Basically, I need to theoretically /mathematically prove an event happening. And then experiment to confirm my results. To see if the experimental matches the theoretical.

Example of last lab: we tried to find if mass effects terminal velocity. Etc.

This experiment has to involve "work" (energy etc)

Prove that a projectile's (when launched and landed at the same elevation) time of rise is equal to its fall.
