During our Science supplementary lesson on 4 October, my pupils had an experiment to find out whether different objects are magnetic or non-magnetic. The pupils grouped into groups of 4 or 5. Each group was given a bar magnet and a bag (consisting of a wooden stick, cardboard, paper-clips. balloon, iron nail, steel plate, aluminium foil, marble, paper, plastic spoon and granite). They had to cooperate and observe whether the object is attracted or not attracted by the magnet. Pupils had a lot of fun. They also did an experiment to find out which parts of the magnet is the strongest. Pupils were amazed at the number of paper-clips that can be attracted by the poles of a magnet. :)
