Description

The Ancient Greeks discovered lodestones 2,000 years ago near the town of Magnesia. These stones had a strange property to attract other metal objects; they called this ‘magnetism’. They discovered the magnetism could be transferred to a nail when it was stroked along a piece of lodestone.

Classroom Ideas

Invite students to use everyday magnets to attract different objects. Paper clips, scissors, screws, nuts, and bolts for example. Encourage students to think about how they use magnets, how they work (atomic magnetism. magnetic domains and magnetic poles) and why they are useful. Students could investigate a real world application of magnets, such as the sorting of metals for recycling.
