Squishy circuits are a great activity for students of all ages to gain a hands-on exploration of electricity and circuits. This resource contains good information on circuits, polarity, and recipes to make conductive and insulating dough. Store bought play dough has conductive properties that can be used for this activity, but homemade dough will be more conductive. If a battery pack is not available at home, using the battery with a paper clip secured at each end with electrical tape will work also. Overall, this is a fun activity for students to try a variety of circuit set up with the dough and test variables that could affect the power.
