Holiday Lights: Play-Doh Circuits – Student

Summary

Students build and compare series and parallel circuits using Play-Doh, LED diodes, and a 9-volt battery, connecting their findings to how real holiday lights work. The five-part investigation covers LED polarity, circuit construction, voltage and current distribution, and a CER analysis. Designed for middle school physical science, with built-in reflection questions and a final real-world application section.
