Testing for conductivity
In this activity, students construct simple electrical circuits and test a variety of materials to identify those that are good conductors and those that do not conduct electricity.
Mechatronics
Professor Dale Carnegie explains mechatronics. Mechatronic products range from machines at home to complex industrial robots with a variety of uses.
By the end of this activity, students should be able to:
construct simple electrical circuits to test the conductivity of liquids and solids
predict if a material is a good conductor and test their hypothesis
rank/group materials according to their conductivity.
