How does a bevel gear, a belt gear or a rack and pinion gear work? What happens when the transmission ratio changes? Young students age 7 and up can investigate these and many other questions using 15 models and twelve experiments. The models can be set up quickly and easily in the classroom and can be used optimally with the help of the ready-made tasks and solutions.

• Main topics simple gear types/ratios, directions of rotation, types of motion of gears
• Includes downloadable teaching and activity materal (free download)
• Set includes gears, bevel gears, rack, belt, chain, axles, building blocks, base plate 120x60 mm.
• Ideal complement: STEM Gear Tech

Explore optical phenomena, and experiment with light in class! Explore penumbra and umbra, discover many exciting things with a magnifying glass or determine the time with a sundial. These and many other exciting topics can be taught in an engaging and hands-on manner using the CLASS SET Optics. In addition to the six models, which can be built quickly and are therefore easy to teach, the kit offers six exciting experiments.

• Main topics optical phenomena / light experiments, magnification, reflection, light & shadow
• Includes downloadable teaching and activity material (free download)
• Set includes lens f=25mm, lens f=80mm, mirror, 2x LED, holder for 9V battery (battery not included)

Renewable energies are becoming increasingly important to our future.  The CLASS SET Solar Energy is the perfect method for introducing young students to this vitally important topic. With three quickly assembled models, the basics of solar energy can be taught in class using ten ready-made tasks, including solutions, with lots of fun and exciting insights.

• Main topics energy generation from renewable solar energy, series-parallel connection
• Includes downloadable teaching and activity material (free download)
• Set includes 2 solar modules,  1V solar motor, mini push-button

This high quality and durable solar panel was designed to produce the desired power output to power the Dr. FuelCell Reversible Fuel Cell #KO348E. This unit was originally part of the “Alternative Energy Kit” used with older PLTW sets incorporating fischertechnik. It can be used as stand-alone unit, but users must be sure it meets their specific technical requirements. Please review the specifications in detail to determine if this is right for your project.
