I originally built this toy using a Canadian nickel coin. Canadian nickels are made of pure nickel, unlike U.S. nickels, which contain so much copper that they are not magnetic. You can build the toy with the nickel or with the Radio Shack rare-earth magnet.
In this science project, you are going to use different types of dried beans like pinto, kidney, and great northern beans to represent protons neutrons and electrons. You will select 5 atoms per group and proceed to build models of these atoms on paper plates using Elmer's glue. You should also include ions and isotopes as variations of these atoms.
