Electron Charge Lab
Activity Overview
Student may experimentally determine the magnitude of the elementary charge on an electron.
Before the Activity
This lab appeared in The Science Teacher magazine, April 2002 edition.
During the Activity
The file attached in the article submission to The Science Teacher. I use this activity to teacher students in first year chemistry about the mole concept. Then I repeat the activity in AP Chemistry and talk about the electrochemistry.
After the Activity
Review student results:
