Which side goes down?

Your child pegs the sock to one end and the spoon to the other. Which side went down? That side holds the heavier thing. Swap them over to check, then try other pairs.

Big but light
You need: The hanger balance, a paper plate and the metal spoonAsk your child to guess which is heavier: the big plate or the smaller spoon. Peg one to each end and watch. Talk about what happened: bigger things are not always heavier. Look around the room for another big, light thing and a small, heavier one to test.
