With this collection of science kits, you and your students can explore the concepts behind and the many applications of solar hydrogen, direct methanol, and other fuel cell technologies.

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.
