Take-Apart is a great introduction for kids into the world of tools, building and fixing. The article below was one of my first experiences with a group of kids.  Old VCRs and tape decks were the best because that had lots of interesting parts. The newer stuff is not so interesting. Taking things apart led me to building a Rube Goldberg machine and Electricity Board for kids both described in other blog posts:
