Where can I get electronics learning kits for the little ones?

Question

Arduino

I know that there are such kits for electronics (for the smallest ones), roughly speaking, you connect the elements and something happens - a light bulb lights up, for example.
Here I want to unobtrusively slip such a son.
Please tell me where to get these. I will be glad for links, etc.
I mean something similar but simpler.
