Turn your students into human gyroscopes with our wide, stable rotating platform. Now you can do the "skater's spin" without skates, a rink or ice! Our 16" (40cm) wide bright blue wooden disc has a nonslip surface and safely holds over 220 pounds (100 kg). Intended for hands-on (or feet-on) use, the unit has very low friction when supporting a weight of 100 pounds. Instructions describe experiments in rolling friction and gyroscopic precession with sample questions. Features include non-skid decals on surface for safety, and bright blue 16" diameter wood discs.

This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.

Physics Pro is our biggest, most advanced physics kit. With this kit, you can continue your study of statics and dynamics from previous lessons and begin your study of more advanced topics in physics, including fluid dynamics, energy, oscillation, hydraulics, and pneumatics. By adding advanced topics like fluid dynamics to your physics repertoire, you can now build some really spectacular models and devices, such as a wind tunnel, pneumatic shocks, and a hydraulic lift. You will see how physics extends far beyond the classroom, giving us an amazing set of tools that can be applied in the real world to engineer marvelous things. The main focus of the kit is the behavior of the two most important fluids in our world €” water and air €” and objects immersed in them. You will investigate how air and water rest and flow, what they can carry and how they move. With experiments and models, you will find out what forces work on them and what kinds of energy they possess. You will learn how ships float and airplanes fly, why a streamlined shape lets a car drive faster and how power plants convert a current of water into electrical current. The 96-page, full-color experiment manual has two major sections. In the first part, you will enter the physics lab, where you will get to know the properties of air and water and become familiar with currents and energy. There is a series of 17 experiments in which you will start building smaller models. In the second part, you will move on to the workshop, where you will build 14 larger models of complex real-world devices. More than 212 parts are included in this kit, which are compatible with our other Physics kits.
