The test to see if Cheetos, or anything, conducts electricity is easy - turn a multimeter to the connectivity setting (it usually has a symbol that looks like a speaker), and touch the probes of the multimeter to a different side of the thing you are testing. We touched the probes to either side of a Cheeto and quickly determined that they do not conduct electricity.
To make the experiment a little more interesting, we wanted to determine if Cheetos resist or help the flow of electricity through water. This was our experiment.
|Tap Water + Cheetos||165|
Here's a small factoid we discovered. The resistance of milk can be used to determine the health of of a cow. Here is a link to a study that was done on buffalo cows. There is a high correlation between a higher than normal resistivity in milk and infected cows.
This was a fun project. The kids liked learning to use the multimeter, and they liked coming up with different liquids to test.
