Science: Pulley System

How does my pulley system work?

How my pulley system works is you turn the pulley stick and it lifts the elevator.

My hypothesis:

I think when you turn the pulley counter clockwise it will turn the lift the string and the elevator and when you turn it clockwise it will lower the string and the elevator.

My procedure: Step by step

Step 1: Gather materials.
Step 2: Make structure to hold pulley system.
Step 3: Make the elevator box.
Step 4: Poke hole in each wall.
Step 5: Put stick through hole.
Step 6: Tape stick making the stick not be able to come off of the structure.
Step 7: Poke holes across from each other on the elevator box.
Step 8: Wrap a string around your stick.(Leave room to tie the string to the holes of your elevator box)
Step 9: Tie the string to the holes of your elevator box.
Step 10: Decorate!
