Mega Bounce

In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment. Learners first measure how high different kinds of balls bounce compared to their release point and then repeat the testing but release two balls at once, one atop the other. Learners will observe some very surprising and entertaining results. While one ball will go sky high, there is also a measurable difference in the bounce of the bottom ball. Relates to the linked video, DragonflyTV GPS: Baseball.
