Will It Conduct?
Description: Conductivity is an excellent way to classify material by their observable properties. Conducting material (e.g. metal), non-conducting material (e.g. plastic), and semi-conducting material (e.g. graphite) should all be used. A simple circuit with a lightbulb is used to determine the conductivity of different materials. These properties can be used to determine if a chemical change has occurred by testing before and after substances have been mixed. These properties can also be used in the design of an engineering solution.
