This book contains graphs showing data collected from a ping pong ball floating in containers and natural waterway. In a series of graphs, the ping pong ball is dropped, submerged, and allowed to float, and its motion tracked. Additional graphs also show the motion of oars and paddles, including rowboat-style oars and a kayak paddle. These data can be used for lesson plans by teachers and parents.
