Ever expect to get preschool activity ideas from NPR? Sean was listening to the radio and heard about Squishy Circuits. So one day, after a trip to Radio Shack, he and the kids set to work.
First, we made some conductive playdough (thanks to salt and cream of tartar).
Next, the insulating dough.
Now it's time to make some circuits!
Getting the lights set up...
It works!
That day, we learned that LEDs are polarized- we kept having to switch them around to make them work.
Then we just experimented for a while. Playdough circuits: fun for all ages!
