LI: To learn about pulleys.
This week learning for inquiry was all about pulleys.Another simple machine that we learnt about for inquiry was a pulley. A pulley is a rope passing through a wheel to lift something. For example we got two training sticks and a rope, we tied one side of the rope to one of the training sticks and we made a loop around the other, four people are holding both sides of the sticks, one person is then pulling on the rope so that it can pull the opposite stick across, we found out that pulleys half the amount of force being used to lift something.
