Science

This is a photo of an experiment we did in science class. All you do is take 2 poles, wrap a rope around it and pull. It takes 3 people! It’s really hard to hold on without moving when the rope is being pulled! We used a block and tackle pulley. The person that is pulling the rope is more likely to be able to pull the people with the poles. We did this to show how pulleys and mechanical advantages work.
