Bests & Worsts Reviews from Amazon

My 5 year old son has an interest in how things work and likes to "experiment." We go this as a first step toward learning about electricity, and it has not disappointed. The projects range from fast simple ones (can get a light bulb and a switch going in a minute or so) to more elaborate more interesting ones (we actually built a working AM radio). There are endless projects in the book with easy to follow directions on how to put them together. The "snap" mechanism for connecting components is extremely clever -- it eliminates the challenges of bad connections on wiring boards I grew up with. The snaps are a little hard for a 5 year old to push close, so I find myself helping on them -- although the kit is aimed for somewhat older kids anyway. Only "complaint" I have is that they could have put a couple educational points about how the circuit is working in the book near each circuit -- to spell out the "learnings" of each project. Overall though, this is definitely one of the best science kits of any type that I've seen, and absolutely worth the investment.
