In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills. Learners predict which quarter will hit the floor first during this free fall experiment. This activity not only requires learners to observe carefully, but also listen carefully! Relates to the linked video, DragonflyTV: Hockey.
