The easiest way, if you're growing the bacteria in a liquid medium is to use a spectrophotometer to measure the cloudiness of the culture. It's very simple, IF you have access to a spectrophotometer.

Alternatively, if you have access to a microscope and a hemocytometer slide, you could actually count a sample of the culture at different times.

Only materials needed: test tubes, medium, agar.
