Growing Bacteria - Petri Dish

Order now at http://www.stevespanglerscience.com/search?sSearch=agar&sClass=Product&am... You can smell a good science project a block away. In this case, multiply the fun by six and you have one of our most popular science fair project kits. You'll get six large Petri dishes, 10 cm (4 in) in diameter, a microwave safe plastic beaker, cotton swabs and the highest quality nutrient agar. This is the same nutrient agar used by microbiologists to grow really funky stuff in the lab. The instructions give you great suggestions for collecting samples and ways to gross out your parents.

In order for this to have any validity, it needs to be a sterile petri dish and he shouldn't be breathing all over the agar---there are many things wrong with this demonstration! Use this video only if you want students to point out what he did incorrectly--only then is it useful!
