We tested electronics kits with kids ages 7 to 12 and got feedback from parents and makers to find the most engaging ways for kids to learn about electronics.

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully ...

The LED is glowing less brightly because play dough has some electrical resistance. The more play dough a current has to pass through in a circuit, the dimmer the LED will glow.

“The LED may also flash when the E and C leads are switched, but the flash rate will be faster,” Gerbig explained. “This reflects the fact that some types of transistor will operate with their emitter ...
