Kids can do more than just play with new electronic gadgets — they can also learn how these things work. Snap Circuits by Elanco is a series of kits with simple circuit boards on which project components simply snap into place: no soldering or alligator clips required.
The Snap Circuits Jr. SC-100 starter kit is $34 here. (Affiliate link.) It has 30 reusable color-coded parts to build 100 projects and experiments such as a dual-speed fan, periodic doorbell, photo sensor police siren, flashing laser light and more.
The kit has won the Seal of Approval from The National Parenting Center, as well as other awards.
