First Class had lots of fun exploring and investigating with magnets!
First we brainstormed “forces”. Magnets are a type of force. We had lots of different styles of magnets to explore with, including bar, donut, horseshoe, wand and disc magnets.
Each group was given a box of items (pegs, toy cars, blocks, 5c coins, 10c coins, paper clips & pencils) and after making a prediction about whether the item was magnetic or not, we could then test using their own wand magnet.
…
Most of our predictions were right except for one! We mostly predicted that the 5c and 10 c coins would be magnetic. However we discovered that yes the 5c coin IS magnetic but the 10c coin IS NOT.
…
It’s to do with the metal! 5c coins (bronze ones) are made of copper which is magnetic. However the 10c coins (gold ones) are made from a type of gold which is not magnetic.
