Combine engineering and alternative energy (solar, hydro & wind) in this high-powered, high-energy class. Build cars, cranes, drawbridges and more from LEGO® kits and operate them using alternative energy sources. You and your team will experiment with wind, water, and solar panels to build waterwheels, windmills, Ferris wheels and solar cars. You'll develop an understanding of how energy is produced from the sun, wind and water. On the last day, use the concepts you've learned to design and build a test car and compete against your classmates.
