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 poster for pulley and we had to answer the questions on the poster. We then had to use rope and sticks to see how pulleys work. We first started with one person pulling the sticks into them with the rope. Then we used the rope to make a pulley and made one loop. It was easy but not really easy. We then added 6 loops and it was way more easy.
