Marbles, Inertia, and Paper Plates


This experiment started out as a Science Photo Challenge and got such a great response that I wanted you to experiment with it yourself. It is a wonderful physic puzzle, and offers interesting insights into the science of force and motion.

To try this, you will need:

  • a paper plate
  • scissors
  • a marble or other small ball

Lets start with the question from the Science Photo.

Catching Money

This experiment is one that I was reminded of while presenting a teacher workshop on hands-on science in the classroom. We were going over some of the easy, spur of the moment things that you can do for science, and one of the teachers reminded me of this one. It is fun and a bit amazing too.

Boomerangs

This week's experiment comes from conversation I had with some talented science educators. We got into a discussion that ranged from gyroscopes to bicycles. The conversation led us into talking about boomerangs, so of course we had to make some paper ones to play with. The dynamics are a bit different with the paper ones, but they are still lots of fun.

An Easy Swing?

I have taught several classes on Amusement Park Physics, and I usually include several activities on the carnival type games. Those games often use science, making something look simple and easy, when it is actually difficult to do. This activity is based on a carnival game where you try to swing a weight on a string and knock over a bottle.
