Early Years STEM Activity:
Inspired by Squishy Circuits website we decided to play around with dough and the simplest equipment: Dough (shop bought play-doh or homemade salt dough), LEDs (from your local electronics shop or some old Christmas tree lights) and 9V batteries. If you have some crocodile clips it helps but it’s not essential!
Here is a circuit with out crocodile clips! To get your LEDs to light you need two separate pieces of dough connected to the two terminals on the battery and the LEDs have to connect the two pieces of dough to complete the circuit. LEDs only allow current to flow in one direction, so if they don’t light turn them around!
Don’t test the LEDs by touching them on the batteries directly as this will damage them! We tried AA batteries but the current was too small. We also tried Christmas tree bulbs, but the current was too small to light them (LEDs need much less current).
Now add curious toddlers and parents!
Dough play with a new twist! Could this be used to get daddies involved in dough play?
