4M Green Science Solar Rover, DIY STEAM Powered Kids Science Kit, Boys & Girls Ages 5+

Overall, kids think this rover is cool and it does teach them about solar energy in a fun manner. That said, the kids (grade 5) put this together themselves and were outside on a super sunny day and the rover did NOTHING! When we came out to inspect it, it turned out that the black and red wiring was not making any contact to the electrodes underneath the solar panel itself. We popped the panel out of the housing and saw that the + and - were flipped to the top of the rover when they should have been at the bottom. We popped it back in the right way, inserted the wires so they touched the electrodes of the solar panel and the rovers motor started spinning immediately. For those of you who also have the same problem, double check that the wiring is making contact with the correct part of the solar panel. :) Enjoy!

Bought as a gift for a 7 year-old niece, who loved it ( along with her 4 year old brother ). Was skeptical that the small PV panel would actually supply enough power to drive the kart along, but it did just fine. The kids loved seeing how they could stop and start the kart by putting it sun vs. shade. Instructions are adequate but could be confusing if one is not technically inclined. I would imagine that most kids would need some help assembling the components correctly but they can definitely still follow along and benefit from learning how gears, motors, electricity, and solar energy work.

Decent value for money and he learned alot from it. He is 10 and used it for the science fair. No missing parts and worked.

This is a great simple kit. Any kid that likes to assemble stuff or learn how things work will have some fun with this. My son is looking to add a simple switch in the circuit to be able to disconnect the solar panel from the motor. He kept trying to get his dad to drink a beer so he'd have a can, but it works just fine without the can! The can serves no functional purpose... just aesthetics.

The screws were a little hard to get in but the directions were easy to follow and it was so cool to see it work!!

Bought this for my daughter who likes to assemble stuff. It takes her only ten minutes to put it together. The parts look flimsy at first sight, but won't break if you're careful.My only concern is that the solar panel is not very sensitive to indoor light unless you just put it under strong incandescent light bulbs. Since it is most cloudy recently, my daughter has not had the chance to try it out in the sun yet.Besides, if not for the 5 buck discount, the price seems a little too expensive.

The 4M Solar Rover Kit teaches children how to harness the light of the sun to power everyday objects. Transform a recycled soda can into a solar-powered rover. This kit includes all the parts necessary to build one solar-powered car.

My son and I had fun putting this together. It works and helped him do something new
