Squishy Circuits in Kindergarten

Today I was doing a workshop with the kids in my daughters kindergarten. It is a Montessori Kindergarten and they have an experiments day where they learn about physics by trying things out. So I told them about Squishy Circuits and asked if there is interest in trying that with the kids and soon enough I was asked if I could just do that. And that’s how i ended up doing a workshop with them – building an electric circuit.

I was impressed on how the children instantly understood and were able to fully reproduce what I showed them, some already trying out own ‘circuit designs’. But what I really  enjoyed was the overwhelming happiness the kids showed about their experiments and how happy they got once the LEDs started to lighten up.

There were pictures taken but I need to clear with the kids parents first if it is OK to post them, until then here some shots of the tools i brought.

A box with LEDs:


A windmill with a solar motor that runs with low current/low voltage


A piezo buzzer. That one was the kids favourite  🙂


A bunch of motors. Unfortunately they do not work for squishy circuits as they require too much voltage.


Cables with switches.




More cables 🙂


A battery box for three AA batteries


One box per child


The most important part – the dough. The green one is insulating while the yellow one is conductive.


a test circuit to see if everything works as expected. The LEDs which are less bright are purple and pink ones, they are not low current LEDs which is clearly visible 😉
