Though some might consider electricity to be a phenomenon best studied by physicists and engineers, our understanding of it is deeply rooted in the study of chemistry. Electricity is the flow of electrons, it can be generated by chemical reactions, and electrical energy can drive chemical reactions. Electrolysis is a process that uses electric current through a solution to cause an otherwise non-spontaneous oxidation–reduction reaction to occur. Students will investigate electrolysis in solutions and use their observations to answer the Driving Question, "What evidence can we use to support the claim that electrolysis is occurring when electric current passes through a solution?"

Time Requirement
Total, 120 minutes. Teacher prep, 15 minutes; prelab, 30 minutes; 4 investigations, 60 minutes; and assessment, 15 minutes.

Digital Resources
