Activity 4 - Magnetic fields Groups use paper sheets, iron filings and bar magnets to explore magnetic fields. Distribute bar magnets to groups. Ask participants to predict what will occur when iron filings are poured on the paper over the area where the magnets reside. Pour iron filings on the paper. Participants observe and record results.
Groups report out and explain magnetic field phenomenon.
Predictions for test objects These objects will stick to the magnet. These objects will not stick to the magnet. These objects stuck to the magnet. These objects did not stick to the magnet. These objects will not stick to the magnet.
