Gravity and Magnetism: A Battle of Two Forces—Super Value Laboratory Kit
An introductory activity familiarizes students with collisions by rolling steel balls into each other at various speeds on an aluminum track. This activity will give students a qual- itative understanding of how momentum
is conserved. The guided-inquiry activity challenges students to design a procedure to explore momentum conservation in a more quantitative manner.

Magnetic Linear Accelerator— Demonstration Kit
This unique demonstration shows the funda- mentals of the conservation of energy and momentum principles as well as the prop- erties of magnetism. Use this accelerator
to launch a ball bearing to study projec- tile motion. Background information and complete instructions are provided.

Water Wheel Generator—Historical Inventions laboratory kit
A water wheel and a simple AC generator are combined to construct a hydroelectric gener- ator that will enhance students’ engineering skills and allow for a full appreciation of a monumental development from the Industrial Revolution! Complete for 24 students work- ing in groups of 4.

Maxwell’s Wheel
Demonstrate the relationship between potential and kinetic energy, linear momen- tum, angular momentum, nearly elastic collisions, inertia and torque. When the wheel is dropped, gravitational potential energy is converted to kinetic energy. The jerk when the wheel reaches the bottom reverses the linear momentum, causing the wheel to wind back up.

Conservation of Elastic Potential Energy—Advanced Inquiry Laboratory Kit
Students propel a spring-loaded cart up an inclined plane and discover the effects (if any) of the inclined plane’s angle and cart’s mass on its travel distance up the inclined plane. Then a guided-inquiry activity challenges students to quantify the amount of energy lost by the cart due to friction and propel the cart up the plane a specific distance.
