High School Physics Presentation Ideas help!

[Zack2005]

Hi, I am new here, but I am in need of some help. I am in a High School Physics Honors class, and I was wondering if anyone had some ideas on a good quick presentation with a demonstration that gets the class involved. Please note that the maximum time is set at 10 mins, so this must be a quick presentation. Any help is greatly appreciated thanks!

Try to apply certain principals of physics under certain conditions such as water, friction ect and have the class estimate what will happen then explain your findings. I can't come up with anything else right now. Once you choose something I'd recommend getting your teacher's opinion on it as well.

Get a couple of skate boards. Have a heavy person whose weight is known stand on one. Then have students come up one at a time and stand on the other. Have one person push the other person, and measure how far each skateboard travels. Then compute the weight of the other person. Have a bathroom scale handy to verify your results.
