Electrochemistry—Laboratory Kits
Build a Dry Cell Battery—
Student Laboratory Kit
By: The Flinn Staff
Generate electricity using two common materials—aluminum and air! By connecting their batteries in series and parallel and measuring the changes in voltage and current, students learn about the properties of electric circuits. They may also test modifications of the battery to improve its performance. Concepts covered include electrodes, oxida- tion–reduction reactions, voltaic cells, electric circuits, voltage and current. Includes complete instructions with sample data and answers to all questions.
Complete for 30 students wroking in pairs. Multimeters are required for quantitative measurements, and DC motors are recommended for each lab group; both are available separately.
Create Your Very Own Simple Battery— Guided-Inquiry Kit
By: The Flinn Staff
Students learn about electrochemistry and galvanic and electrolytic cells in a fun and challenging way as they create their very own tiny, simple, handheld batteries. Students will be amazed when they successfully assemble a cell using a few simple materials and dilute sulfate solu- tions and then see proof of electric current when the LED lights up. The experiment is in two parts and can be completed in a single 50-minute lab period. First, an introductory procedure helps students prepare their own materials for the challenge. Then, the guided-inquiry portion leads them through assembling the cell and identifying the different parts. A background section is included to provide a concise overview of elec- trolytic and galvanic cells, while post-lab questions solidify the activity and promote student success.
Producing Metals with Electricity—
Student Laboratory Kit
By: The Flinn Staff
Pass an electric current through a solution and collect pure silver metal! Students investigate the reactions of copper, zinc, and silver salt solutions in a partitioned Petri dish with mini-carbon electrodes. A simple 9-volt battery serves as a power source. A great activity for an applications-oriented chemistry class. Includes metal salt solutions, partitioned Petri dishes, battery caps with leads, pencil lead electrodes, reproducible student handouts, detailed background information, and Instructor’s Notes with sample data and answers to all questions.
Complete for 30 students working in pairs. 9-V batteries are required and available separately.
