There are three forces push, pull and twist gravity is a pull force to pull us down to the ground.
If there was no gravity we would be dead and floating round in space .
For gravity we made parachutes and a playdough ball we threw the ball down 3 times then we put the small parachute on and threw it down 3 times then the medium parachute and threw it down 3 times then we done the same with the big one the parachutes made the balls go down slower.
At the end of the day when we where making and using gravity miss dale tied a big tarp on to Larsson and we ran down the hill it was to slow him down like the parachute did to the playdough ball.
