Dr. Shawn’s Science Fair Success Series
This brief video explains how to perform Serial Dilutions-- a bedrock technique of science. Learning this simple method will empower you to perform thousands of different experiments.
The Solution to Serial Dilutions or
From Full Strength to One Part in a Million in 5 Minutes Flat!
By Dr. Shawn
Few laboratory techniques are easier or more useful than making serial dilutions. Basically, serial dilution lets you start with some chemical at full strength, and then quickly create a series of concentrations that ultimately could be as tiny as you like. This method has many uses, but many science fair students will find this technique useful for finding the smallest concentration of a chemical that affects the object of their experiment--for instance, the smallest concentration of some nutrient that affects mold growth, or the smallest concentration of an anti-bacterial agent that kills bacteria.
