Hydrogen Power: Exploring Electrolysis – Student

Summary

Students read about hydrogen production methods and color labels, then build and operate a simple electrolytic cell using a 9V battery, graphite pencils, and tap water to observe hydrogen and oxygen gas production. The lab includes structured reading, comprehension questions, a hands-on construction procedure, and analysis questions connecting experimental results to real-world hydrogen production. Works well for high school chemistry, Earth and Environmental Science, or an APES energy unit.
