Enrich your students' study of oxidation-reduction reactions, electrochemistry, pH, and stoichiometry with this student-engaged, teacher-led demonstration. Students make predictions about the results of water electrolysis and observe a colorful, intuitive activity. They then illustrate the decomposition of water and the flow of electrons through an electrical circuit.

Enrich your students' study of oxidation-reduction reactions, electrochemistry, pH, chemical bonding, and stoichiometry with this student-engaged, teacher-led demonstration. Students make predictions about the results of water electrolysis and observe a colorful, intuitive activity. They then illustrate the decomposition of water and the flow of electrons through an electrical circuit to help explain the concepts. Students' knowledge is extended by brainstorming real-world and career applications of electrochemistry. With Carolina Chemonstrations®, students are active participants in demonstrations. This demonstration requires approximately 15 min and materials are sufficient for 5 demonstrations.

NOTE: Instructions for this kit are based on the predict, observe, explain (POE) model. POE is primarily used in science classes. Specifically, POE has optimal effects when paired with demonstrations that allow students to make and record observations and then follow those observations with explanations.
