For slightly older kids, I would highly recommend Direwolf20's Feed the Beast Let's Play series. FTB is a collection of mods that adds entirely new tech trees to the game (amongst other things), allowing you to build advanced power generation such as nuclear and geothermal, logic gates, and even programmable bots/turtles (programmed in Lua). Direwolf's videos are instructive and fun, and his language is appropriate for kids. http://www.youtube.com/user/direwolf20 http://www.youtube.com/user/direwolf20
