Here are some student reflections on the activity:
"We're using the pulley to lift the load (the weight) up. The spring scale measures how hard it is to lift it." ~ Nikita
"We're pulling down on the rope which makes the load go up. It's easier because you don't have to carry it up a ladder or stairs." ~ Charlotte
"This is a three pulley system. It makes the job easier. It was difficult to make because it kept falling a part." ~ Abigail and Ina
