Who does not love to play with magnets? Students have common misconceptions about what materials will attract to a magnet. This activity allows them to try out many different materials to determine what will attract. Let them try anything reasonable but direct them to try as many different materials as possible. Most students gravitate towards metal, but find out that not all metals will attract. In fact ONLY materials made of Iron (steel), Cobalt and Nickel are metals that attract to a magnet.
Spend some time in the beginning discussing the difference between sticking and attracting. Magnets ATTRACT to materials, they do not STICK. There is nothing ‘sticky’ about a magnet!
