Squishy Circuits is a project developed at the University of St. Thomas for the purpose of creating tools that students can use to create circuits and explore electronics. Squishy Circuits uses Playdough-like to enable hands-on learning about conducting and insulating currents as well as creating circuits. The Squishy Circuits website provides directions for creating the dough and offers ideas for lessons using the dough. Watch the TED Talk below for an explanation and demonstration of Squishy Circuits.

Applications for Education
Creating Squishy Circuits could be a great hands-on science activity for elementary school or middle school students.
