Year 3 – Physics – Pulleys

Year 3 children have really enjoyed learning about magnets and forces this term. In today’s session, children learned about a pulley system to lift weight, before attempting to make their own. Children learned how this invention can make lifting heavier loads much easier.

How to make a Pulley?

Learn how simple physics helps make everyday life easier. Make your own pulley system at home. You will need some wire, thread, a spool, a hook and a bucket filled with toys or other materials. After assembling the pulley, first try and lift the bucket with your hands, and then again try lifting it with the pulley. Which one is easier?

Sometimes, it’s not easy to lift heavy objects with only human force. This problem can be fixed with the help of a simple machine like a pulley.
