Circuits

We've been discovering electric circuits this week. Brain Box sets are a wonderful way to do this. Lots of experimenting and investigating!

And then the following day we used two different types of playdough to make 'squishy circuits'. The Green play dough was made with a lot of salt, giving it low resistance, and the yellow one was made with sugar, giving it high resistance. Here is a website showing you a short TED talk about it.
