The Good, the Bad, and the Complex Part 1: The Good—Lactic Acid Bacteria

Students investigate some of the claims companies make about probiotics and learn several key techniques in biotechnology (including aseptic technique, spreading, pipetting, sterilization using a burner, etc.). They also integrate a fair amount of math in order to cross-check companies' claims and also to plan for and perform serial dilutions.

These materials were developed by ABE Master Teacher Fellow Declan Cathcart of ABE Ireland as part of the ABE Master Teacher Fellowship.
