1. Collect a set of small objects, both metallic and non metallic. Use a magnet and wave it in the proximity of each of the objects. Sort them according to whether or not they get attracted. What are the constituents of the objects that got attracted.

2. Mark one magnet such that one end is marked with a red cross and the other with a blue cross. Take another magnet and bring one of its ends close to one of the crosses. If it repels mark that end of the second magnet with the same colour as the one it is close to. Otherwise mark the other colour. The poles are now identified.
