To conduct or not to conduct ... that is the question! The sixth and final video in a series depicting elements, mixtures, and compounds digs deeper into the concept of conductivity. Pupils learn how the arrangement of electrons within a substance either promote or inhibit conductivity. The content also includes a discussion of superconductors.

Instructional Ideas

• After watching the video, pose the question, "Why would someone need a superconductive substance?"; then have the class research the answer
• Have volunteers rub balloons on their hair to demonstrate a how electricity influences a nonconductive substance

Classroom Considerations

• Some prior knowledge of the arrangement of electrons in metals and nonmetals is helpful

Pros

• Teachers can use the pauses embedded within the video to check understanding and to promote class discussion
• Simple animations provide visual reference to help them comprehend the concept

Cons

• None
