Mythbusters- squishy circuits! can you pass a current through play dough? Testable question

Winter session of stem club has begun! I cannot believe that we have 13 girls for this STEM club session! They were excited to begin! For our first session, I decided to try some fun science experiments that were inspired by the television show Mythbusters. It’s a great show, and I love the idea of trying experiments¬† out to see if they work.

I’ve been teaching third grade for 5 years, and each year I teach a unit on electricity.¬† I have heard that you can pass a current through play dough, but I have never tried it. I thought it would be a fun experiment for my STEM club girls to do! The best part was that I would be learning right along with them!

We started by watching a short clip on Mythbusters.

Then we made play dough on a hot pad using salt, flour, oil, cream of tarter, and food coloring. The girls took turns pouring in the ingredients and mixing.

We then talked about circuits and got to the experimenting part. Could they get a bulb to light? A buzzer to work? A motor?

The girls loved finding out!
