Helps students understand how and why gyroscopes are used for many guidance systems. This is a well-balanced, high quality gyroscope with adjustable bearings. The accessories include plastic gimbals, rocker and pivoting housing. This unit measures 100m x 190mm. Instructions provided.
Useful for demonstrating momentum, conservation of energy and torque! The unit is suspended by two strong cords, which are wound around the shaft of the wheel and then released. The wheel will unwind as it falls but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for several moments as the wheel slowly loses momentum and travels less each time. Instructions included.

Almost every form of energy we use originates as energy from the sun
Explore the topic of solar energy, focusing on photovoltaic cells
Learn how solar cells transform light into electrical energy
Learn how motors and mechanical devices can optimize the work done by energy
Build a praying mantis model that moves like an insect and is solar powered
In one way or another, almost every form of energy we use originates as energy from the sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the sun, and Earth's weather systems sustained by the sun. Even the energy stored in fossil fuels originated as energy from the sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. There are 320 parts, which are also compatible with the other kits in our Physics line. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace in Germany.
