WARNING: CHOKING HAZARD - Small parts. Not for children under 3 yrs.
Build & experiment with six different solar powered vehicles to learn about solar energy firsthand!
Explore engineering and vehicle mechanics as you build models like a helicopter, steam locomotive, or bulldozer. Then experiment with one or more photovoltaic cells to energize them outdoors in bright sun (or indoors with a AA battery). You can even design your own solar vehicles with the 177 pieces included in this set! It also includes a 24-page manual with step-by-step instructions for six models, plus scientific information on solar power and photovoltaic cells. Three solar cells are included that produce 1.5 volts in bright sun (not suitable for indoor use). You provide a AA rechargeable battery, which can be recharged with materials in this kit.
