Week 4 catapult

This week we are experimenting and observing with a trebuchet which is a type of catapult. We observed how the trebuchet worked. With the trebuchet, it works a special way, the bucket holds wait and it has a little leather pouch which has a projectile in it, you pull the string which is attached to the weights and it launches the projectile. The more weights you put in the more the projectile went. I wonder what would happen if we put 20 weights in, I think it would go to the end of the field.
I think I am the same on the rubric
