Young scholars calculate a toy car's velocity and acceleration. In this force and motion activity, students build ramps and attach a dropper to a toy car, which is released down the ramp. Young scholars calculate and graph velocity and...

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Students simulate how the Moon causes ocean tides. In this earth science lesson, students calculate gravitational acceleration using a mathematical formula. They compare the force of attraction between the Earth, Moon and Sun system.
