I like to do various semi-education activities with my kids, most often on Saturdays. We call these Science Saturdays activities. I am going to post about some of the successful activities and the less-than-great semi-educational activities.

Green Science Salt Powered Robot

This kit allows kids to put together a snap-together robot in Lego-like fashion. It doesn’t take long to put together, and they learn a little about the science of electricity and batteries along the way. It was an OK kit that the kids were able to follow from start to finish, but it didn’t hold their interest long as the final “toy” was too slow and couldn’t really be controlled, so they quickly lost interest,

Kid Approved? Mhhh

I am giving this an OK rating in that it was able to keep them interested long enough to complete everything, but they lost interest fast and had no interest in returning to the robot toy. We built this when our kids were 4 and 6, and it did work well enough for the 4-year-old to follow along, which is nice.

In the end, at only $10 this isn’t a bad kit if you haven’t done many like it, but we already built a solar-powered soda can car, which goes much faster and can crash / drive off stairs. So that was a bit better and they have revisited playing with the soda can car much more. If you have already done some other battery / electric kits, this one would be low on my list, but if you haven’t done any others, this one is cheap and simple to do with younger kids… However, they also enjoyed a lemon battery light more than this as well.
