♥♥♥♥♥ Battery Science: Widgets that Work
I used this to teach my Webelos Scouts (age 10) how electricity works and make things go. They mostly had fun using the fan to make horrible noises cutting pieces of paper, but they got the point of the experiment.

Requires fine motor skills; may be difficult for some to do without adult help.
