Gravity Experiment

We carried out an investigation, using objects of different sizes and shapes.

We used a Marble, Ping Pong ball, Sheet of paper Rubber, Pencil, Paper clip, Feather.

First we held two of the objects up at the same height, and then dropped them to see which object would land on the ground first.

When we guessed which item was going to hit the ground first, most of us chose the heaviest of the two. Then we dropped them to find out and the lightest item hit the ground first.

This table represents the results:

Object Dropped	Object Dropped	Which hit the ground first?	Which actually hit the ground first?
Marble	Ping pong ball	Marble	ping pong ball
Rubber	Paper Clip	rubber	rubber
