Product Details

Introduce the basic principles of electrochemistry with this introductory level experiment. What happens when an electric current flows through water? How does electricity cause chemical reactions to occur? Students build simple electrochemical cells using a Petri dish, pencil leads and a 9-volt battery and then investigate the chemical reaction that occurs when current is forced through water. By comparing the amount of gas and indicator color changes at each electrode, students identify individual reactions that occur and determine the overall chemical reaction. This safe and economical experiment is also a great “classifying matter” activity to prove water is a compound. Includes reproducible student handouts, detailed background information and complete Teacher Notes with sample data and answers to all questions.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. 9-V batteries are required and available separately.
