Not every metal-looking sample is attracted to a magnet
Test safe objects instead of assuming all metals respond alike.
Invite predictions, then test suitable known samples with an enclosed classroom magnet. Record what this setup shows instead of generalising from shine or colour, and keep loose small components out of the activity.
To hand: An enclosed classroom magnet and large safe samples.
- Predict attraction.
- Test without contact first.
- Record results.
Compare the prediction with the attraction test
A metal-looking object may not be attracted to this magnet.
Choose samples whose identity is known and whose size is suitable. Metal appearance alone does not predict attraction accurately.
Keep magnets away from electronics and small loose parts. What did the test establish?
Use educator-led demonstrations.
