Lab-Aids Introduction to Conductivity
Explores electrical conductivity, develop principles of conductors and insulators and electrolytes/non-electrolytes using acids, bases, salts, alcohols, and hydrocarbons, test a variety of common materials for their conductivity characteristics and differentiate between strong, weak, and non-conductors of electricity.
Manufacturer: Lab-Aids 309
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 kit, 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 can be used as an 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. This kit is packaged complete for 30 students.
