What part of the world are you in? How big of a group are you expecting? What kind of budget do you have? Are there other resources on site? (computers for instance) Depends on the kids background and the size of group. For those with zero electronics experience, battery and a light bulb. Maybe move from there to an LED and get the concept of polarity. Add a little piezo beeper and then they have the makings of an "alarm". The more astute may connect the idea of "circuit" and "circle". With light bulb, LED and beeper you can also get to the concept of series vs parallel which can be worked toward basic concepts of current. (ie. why does the LED work and not the bulb when they are in series?) That can be stretched a bit further if you add a multimeter and work through basic measurements, even Ohms law for the right group. Younglings that are a bit past that level might benefit from a breadboard and a 555. I don't know your budget, but with a bit of planning that could be under $4 a unit. A couple bucks more parts and a copy of Forrest Mimms 555 Mini Notebook would be a treasure to some. I've also had pretty good luck with "take something apart". Microwaves and printers seem to be good candidates. Gives them an opportunity to use tools, see things, ask questions. There are a couple minor hazards you'd need to steer them around (take out the toner cartridge, make sure the caps are discharged, etc). That supervision gets harder in bigger groups. -Denny On Wed, Apr 4, 2018 at 5:55 PM, Neil wrote: > Can use some thinking help here.
