Simple Machines: Home Improvement Edition

Connor's class is studying simple machines. I think he has a pretty good idea here.

Science Homework: Plan a Pulley

Pulleys can be used to raise loads by pulling either from above or below. Think of a problem that can be solved with a pulley in our class or at home. Write a paragraph on what the problem is and how the problem can be solved by using a pulley. Make a drawing of your plan. You may review by looking at pages 410-411 in your science book.

In case you can't read the words Connor wrote:

"It is boring going up the stairs. You can use a pulley so that you can pull yourself up. A chair would attach to a rope and someone would sit in a chair and pull themselves up and a bungee cord would attach the chair to the rope."

Next week? Maybe he'll build the thing and we can test it.
