Product Information

Affordable, Easy, Fun Present these demonstrations in front of your class to excite your students about learning core physics concepts. Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics. Introduce your students to the wave of renewable energy with this hydroelectric demonstration. Featuring a 3.5" wide paddle wheel that is powered by flowing faucet water, students will be able to watch the water energize the wheel which will in turn rotate a motor that generates electricity to power a DC motor, light bulb, or diode. This also provides for an excellent illustration of how an electrical circuit is affected by its resistance. When the light bulb is being used, students will see that the generator turns slower because the light bulb has a higher resistance than the motor, requiring greater water pressure to cause the bulb to light up. Includes the apparatus and demonstration guide. A sink with a faucet hose and drain are required but not included.
