Part of Lesson Plan: **Use of a Multimeter (updated) By Michael Drouin

Activity Overview / Details

I then tell the students this: "It's a little-known fact" (joke to get attention) "that it can also measure brain density/intelligence."  I then instruct the students to do the following:

- Set the meter to resistance.

- Make sure your fingers are in contact with the probes and touch them to your temple.

- I then allow a student to read the number on the meter (it will read a number).

- I then tell the students that if it is a 4.0 (what ever the number is) that's pretty smart. Then I ask another student to do the same with their meter. The numbers will vary until one student will just touch the probe to temple and it will read 0.0 I give him a blank stare, take the probes and check mine again to make sure it still shows a number then have him check again...the light is on, but nobody is home or some other appropriate joke.

- If done correctly, this will get a few laughs and get everyone focused on what you are doing.
