Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Show us your moves. Using sensor equipment, scholars track the motion of different movements, such as jogging, skipping, or jump roping. They analyze velocity and acceleration and create graphs representing each movement.

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....
