Direct participants to place magnets near each other using three different orientations and to record observations. Groups report out and compare findings to predictions. Use the terms force, attract and repel. Ask participants how they might make a temporary magnet with a nail. Distribute nails and paper clips.
Participants draw inferences from findings.
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.
