Electronics are a Snap with Snap Circuits Jr.
Snap Circuits Jr. is an amazingly fun way for kids of all ages to learn the basic principles of electrical and electronic circuits.
The projects are fast, fun, and sometimes noisy. You can make a light turn on and off with a switch or your voice. You can power a fan, make a doorbell, create light-controlled sounds like a fire engine, ambulance, a computer, and more. You can also play electronic games. And all with just 2 AA batteries.
The kit comes with a base grid, over 30 various types of blocks, and a booklet of instructions with 101 experiments to build. No tools needed, everything just snaps together.
It's easy to follow the instruction manual for each project. All the experiments are illustrated in color and numbered so you know which parts to lay on the grid first, second, and so on.
