Today we started learning about simple machines and how they help us to do jubs more easily.
Today we focused on LEVERS. We identified different household levers and learnt about the words fulcrum, load and force. We identified these parts on different levers.
It was fun making a simple catapult with a spoon, blocks and a ping pong ball. (Ooops - one flew off into who-knows-where).
We experimented using a lever, and changed the position of the fulcrum. We worked out that the closer the load is to the fulcrum, the stronger the force was which meant it was easier to lift.
