Read section on magnetism in Harcourt Science level K to T day before. He wanted to do magnetism experiments listed in book. So we did three experiments:
(a) what do magnets attract? We tested magnets on different materials eg plastic, types of metals and we confirmed that magnets attract iron.
(b) Showing that magnetic force can act through some solid objects: Placed an iron object in a glass of water and showed that object was attracted to magnet through glass. Also worked through place mat and cardboard
(c) compared strength of two different magnets by seeing how many paper clips each attracted: counting paperclips
