The purpose of the project is to find the lowest possible height for the hill so all of the marbles can complete the loop. The foam pipe insulation needs to be the stiff kind. If it's too flexible, then it's hard for the loop to keep its shape. The marbles can be any kind. However, if you use a kind of marble that is very heavy or very light, it may affect your results. The supports can be almost anything. They can be books, shelves, ironing boards, wood blocks, and cans (as in a can of soup). The reason I say cans is that sometimes, I play with these things called GeoTrax. They are train tracks that you can run miniature trains on. Sometimes when I played with them, I built so much that I ran out of supports. So I went to the cupboard and got out some cans. They worked almost perfectly for the GeoTrax. So I thought that they might work with this science fair project. But I didn't use them because the height intervals for the cans would be something like 6 inches. That's way too much.
I found this project on sciencebuddies.org. The project is about potential energy and kinetic energy. Potential energy is the stored energy inside an object and kinetic energy is energy in a moving object. The higher an object is, the more potential energy it has. When the object falls, it converts the potential energy to kinetic energy. Thats what happens during this project!
