A clever way to demonstrate the transfer between potential energy and kinetic energy
Create a model car consisting of a simple chassis and a straw-based axle system (simple machine) that produces minimal friction and allows the cars to roll with little energy input, making them ideal learning tools for students of all ages.
Curriculum topics: Motion, Momentum, Friction, Simple Machines, Kinematics, Conservation of Energy

Use this activity kit to demonstrate the effects of friction and air pressure on motion. Create a simple hovercraft and be amazed at how it gracefully glides along a smooth, flat surface on a thin cushion of air. How long a “flight” is possible? Experiment to find out.
