Gear up for a fun activity kit using motors to build ten different mechanical devices. Build a working fan, a spinning game wheel, a conveyor, train, car, and more. — Ideal for science fairs, you can construct and deconstruct the devices repeatedly. Step-by-step instructions are written in a colorful book along with useful facts about motors, magnets, electricity, and gears. — Requires 2 AAA batteries, not included.
1/4 Scale Operating Model Kit — Powered by hand crank, no batteries are required. As you turn the crank at your own speed, each of the parts move. — Engine rests on a black stand, which may be painted. Distributor and coil wires are in actual firing order; scale starter and solenoid are mounted on the flywheel housing; the hand crank operates the crankshaft; pistons and valves; rubber belt operates generator, pulleys and fan; fuel pump with operating activator arm and clear fuel bowl. Glue required (not included). Skill Level III
Create a complete working clean energy system from start to finish. With this revolutionary kit, you will build an entire miniature renewable energy system using water electrolysis and advanced proton exchange membrane technology. — The set is modular so users can learn the system step by step, configure the system in different ways, and discover how renewable energy can be harnessed, stored, and re-used in many applications. After working with this set, you’ll understand how hydrogen is the unique link between natural sources of power and power consuming devices - using fuel cell technology. — Kit includes electrolyzer, 0.3W air breathing PEM fuel cell, water storage tanks, hydrogen storage tanks, mutli-connector, and mini fan modules; a solar photovoltaic cell; tubing and accessories; and a user manual with experiment guide.
This vehicle travels on land or water. The multiple function switch (solar or battery) allows this kit to be energized day or night, indoors or outdoors. Its scientifically structured catamaran design reduces water resistance and makes capsizing more difficult. Skill Level I
