: To Conduct or not to Conduct


Investigate the conductivity of different materials in the interactive investigation
Does it
Conduct?

Complete the following assignment and submit your work to your teacher.

Complete a lab re
port that includes the following:

Problem:

What materials will act as conductors or insulators?

Hypothesis:

Develop a hypothesis to answer the problem.

Observations:

Include the printed table from the interactive investigation.

Discussion Questions:


1.

H
ow would you describe the materials that are conductors? Explain why these are
conductors.

2.

How would you describe the materials that are insulators? Explain why these are
insulators.

3.

Was your hypothesis correct? Explain.

4.

What would your observation be if
you tested a material that was a semi
-
conductor? Explain.

5.

In the investigation distilled water was tested. What would happen if regular tap
water was used? Explain why?

Application:


1.

With an understanding of the arrangement of electrons in the Periodic Ta
ble you
could predict what materials will be good conductors or insulators. Using this
understanding, write a paragraph (5
-
7 sentences) predicting which groups of
elements will be good conductors and which will be good insulators.

2.

Research the molecular st
ructure of rubber, plastic, and glass. From the molecular
structure explain why these are good insulators.

3.

Research one of the following Canadians, Jules P. Carbotte or Louis Taillefer, who
are both leading experts in research on superconductors. In a para
graph (5
-
7
sentences) describe their contributions to the topic of superconductors.
