Developed in collaboration with a science teacher from Pennsylvania, our build your own solar LED Jar light is a fun and creative way to teach and learn about solar electricity. Use your own mason jar or recycled jar and build a colorful LED light that automatically comes on at night and goes off at dawn. Comes with everything you need. This kit requires soldering. Tools needed are soldering iron, solder & flux, hot glue gun, electric drill, 3V 70mA Polycrystalline Solar Panel, Dusk/dawn circuit board, 2 Bright 5mm LED's BLUE, 2 AAA NiMH rechargeable batteries & Battery holder and wires.
A portion of the proceeds from the sales of this kit are being donated to help provide solar lighting solutions to disadvantaged communities in Africa.

This basic aluminum pad and is identical to the pad used in the Science Olympiad National competition, without the pneumatic launching option.

This model acts similarly to the Rabinion planetary gear of a modern vehicle. The complex principles of a planetary gear are unlocked with the use of color coded discs. Blue is used for the internal gear. Green is used for the pinion gear. Yellow is used for the sun gear. This model consists of 3 forward speeds and 1 reverse speed. The instructor or student manually operates this unit by locking by locking down a specific part of the gear using a fixed pin. Changes in rotation are visible when adjusting either the sun, pinion, or internal gear. A nomenclature panel is included on the front of the model for reference. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimention: 27V x 30W x 24H cm; Weight: 3 kg

This product is a model of a differential. This model permits the instructor and student to manually turn the handle and apply a load to the transparent wheels to demonstrate the differential mechanism.
In automotive mechanics, the differential gear arrangement permits power from the engine to be transmitted to a pair of driving wheels, which divides the force equally between them and permits them to follow paths of different lengths, as when turning a corner or crossing an uneven road. On a straight road, the wheels rotate at the same speed. When turning a corner, the outside wheel has farther to go and will turn faster than the inner wheel if unrestrained. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply.
