Pulley

LI: to learn about pulley.
A rope that is around a wheel to pull up a heavy load, which is like a incline plane but pulls straight up. We had a little play with ropes and a stick to see how pulleys work. We first started with one person pulling the sticks in with people holding on. We then used a rope and put a loop on the sticks and pulled with the rope. We then progressively added loops on the stick. We then had a poster with a bunch of questions on and we had to answer questions.
