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.
I hope that you made your own Whistle Stick, and have been playing...., I mean experimenting with it. I also hope that you spent some time thinking about the science behind the sound that it makes, because that is what we are going to explore this time. For your exploration, you will need:
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.
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.
This experiment came as an accidental discovery while working on a different experiment idea. I was playing with ideas for showing how inertia helps remove water from your clothes in the spin cycle of the washing machine. In the process, I saw something interesting, and made a wrong guess about the cause. That led to even more interesting discoveries. There are times when it is more fun to be wrong, because it lets you learn new things.
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.
