Falling for Gravity

Gravity is the force that pulls on every object on earth. Have you ever wondered if the pull is always the same for every single thing? If you drop a penny and a pen from the same height, they'll both hit the ground at the same time. But if you drop a pen and a piece of paper, the paper may drift and take longer to fall than the pen does. Can you guess why? Test gravity with this activity.
