Magnetism is a force that acts over a distance. Children play with magnetic toys all of the time. Any family that has a refrigerator knows that the number of magnets on the door defines the size of the appliance. This story should give students an opportunity to test some of their conceptions about magnets, namely what they will attract, their strengths, their interactions with each other, and how they are used in everyday life. It also allows for a great deal of investigation, testing of hypotheses, and drawing of conclusions.
