my project is a drelavator.

(a drelavator is a drawbridge and a elevator put together.)

My hypothesis:

The elevator will go up.

I will use one pulley that connects to the lift. my pulley will be made from a pencil because a pencil is strong and sturdy.

 

conclusion: 

my hypothesis was correct because I used one pulley and it worked. but I made some changes. my changes were that I made a drawbridge and an elevator.
