A magnet is an object that attracts metal. Magnets can be natural or man-made. Magnetite is a mineral that is a natural magnet. Man-made magnets are made from steel. Magnets can pick up or stick to iron and steel.
Magnets come in many sizes, shapes, and strengths.
Set up various magnets at different locations in the classroom. Groups of students will work at each station, rotating at intervals as instructed by the teacher. Each group has a teacher-prepared observation guide to record data. After students have completed the activity at each center, class should discuss data. The data is used to make a graph to illustrate the results.
