Lab-Aids: Introduction to Conductivity Kit


All materials can be classified as a conductor, insulator or semi-conductor. Materials are classified according to their resistance to the flow of current. A conductor is a substance that is capable of carrying an electric charge from one point to another. An insulator blocks the flow of current. Semi-conductors are neither. Their conductivity lies in between the two.
In Part 1 of this interesting Lab-Aids, students test several common objects to determine if they are conductors or insulators. In Part 2, The students test electrical conductivity in aqueous solutions.They test an acid, base, salt, alcohol and a hydrocarbon. This kit is an excellent introduction for students in physical science, general science and introductory chemistry courses. Conductivity indicators are required for these activities, but are not included with this kit. We recommend the LAB-AIDS‚® Conductivity Indicator. This kit is packaged complete for 30 students. REQUIRES CONDUCTIVITY INDICATORS.
