4M: Green Science - Rover Robot

Took it to the park on a clear afternoon and the little rover actually rolled across the pavement the moment sunlight hit the panel. The switch to battery power for cloudy days is a real lifesaver, and my kids enjoyed snapping the solar kit together before we tested it.

My son loved putting together the solar panel and watching the rover zip around our driveway. It’s clever how it switches to battery power when clouds roll in, so he can keep playing. The build was a fun afternoon project for both of us.

Took this to the park on a sunny afternoon and the solar panel had it zipping across the pavement without any batteries. The dual power option is great for cloudy days, but it's really satisfying to watch it run on pure sunlight.
