Power Up! Exploring Electrolytes Lab – Student

Summary

Students build multi-cell electrochemical batteries using copper and zinc electrodes, then test different electrolyte solutions to see which one powers an LED diode most effectively. The lab includes structured data tables, a class data sharing activity, and guided post-lab analysis questions covering voltage, current, and ion movement. Designed for high school chemistry, this hands-on activity works well in a unit on electrochemistry or energy transfer.
