Serial Dilution... or,
how to count to a million

You be the scientist

In the applet below, you can practice the whole process of serial dilution from beginning to end. If you don't get a good count the first time, try it again.

Hint: this applet previews the module on bacterial growth rates a bit. Specifically, you need to know that the "doubling time" is the amount of time it takes a population to double. So if you start with a population of 100 and it doubles every 10 minutes, after a half hour it has doubled 3 times to about 800.
