ELECTROSTATIC SERIES, Conductors and Insulators

Yesterday we rubbed a balloon with a wool sweater, and learned that neutral objecs can be charged negatiely or posiitively by friction. The question is how do we know which object has which specific charge? Can we see the charge physical to tell which it is?
Well of course not!
We have to use a specific table called the Electrostatic Series.
This can be found in your course kits on pg 5.

Not all objects however can hold or move electrons in the same capacity.
Objects that can move electrons more easily are called conductors.
Objects that can not move electrons easily or resist them are called insulators.

HOMEWORK:
Using your textbook and the word search given today identify which materials are conductors or insulators.

Tomorrow we will be conducting LAB 9A.
There will be a 3 mark pre-lab quiz.
Make sure you know the lab in detail!
The lab can be found on ph 298 and 299.
You will complete this lab in groups of 4 and must complete both parts by the end of the calss.
