For Innovation Day my class and I are doing a project with pulleys. Miss.M gave us three options:

• flagpole
• drawbridge
• barn elevator

I chose an elevator with a  compound pulley. This means a pulley that can hold heavy stuff.

My Hypothesis was it would work great because my pulley system would be sturdy.

 

 

My conclusion was that my Hypothesis was correct.

I did need to add some improvements because at first a dried line of hot glue was blocking my elevators track so I moved my elevator and it ran more smoothly.
