Introduction to Electrical Conductivity

Kit #309

All materials can be classified as either an electrical conductor, insulator, or semi-conductor based on their resistance to the flow of current. In Part 1 of the activity, students use conductivity testers* to test several common objects to determine if they are conductors or insulators. In Part 2, students test aqueous solutions of an acid, a base, a salt, an alcohol, and a hydrocarbon. This kit serves as an excellent introduction for students in physical science, general science, and introductory chemistry courses.

*Conductivity testers are not included with this kit. We recommend using either the Lab-Aids® 9-Level Conductivity Indicator (Product ID 300M-U) or the Lab-Aids® Audible Conductivity Indicator (Product ID CO-002).
