For the textbook, chapter, and section you specified we found
Electrolysis of several aqueous solutions is carried out using a 9-V battery and pencil leads as electrodes. Because only the electrodes are shown in the videos, it is important to show these still images
or describe how the reactions were performed if students are to make sense of the videos. In each case the anode is on the left and a 9-V battery has been connected to the lead of each of the pencils near the eraser end with an alligator clip.
Introducing New Learning Tools into a Standard Classroom: A Multi-Tool Approach to Integrating Fuel-Cell Concepts into Introductory College Chemistry Matthew J. DAmato, Kenneth W. Lux, Kenneth A. Walz, Holly Walter Kerby, and Barbara Anderegg Describes an approach to deliver the science and engineering concepts involved in fuel-cell technology to the introductory college chemistry classroom using traditional lectures, multimedia learning objects, and a lab activity to enhance student learning in a hands-on, interactive manner. DAmato, Matthew J.; Lux, Kenneth W.; Walz, Kenneth A.; Kerby, Holly Walter; Anderegg, Barbara. J. Chem. Educ.2007, 84, 248.
