Agar & Petri Dishes

Use agar and petri dishes to grow your own bacteria cultures!


Growing bacteria is a great science fair project or lab experiment.
Nutrient agar works well for general use. To make an agar plate, just heat the agar and pour it into a sterile petri dish. Rub a swab along a surface you want to test (your mouth, the bathroom counter, etc.) and then smear it in a zig-zag pattern on the surface of the agar plate.

To get started: The Bacteria Experiment Kit has everything you need in one convenient set. The Gram Stain Kit has everything you need to test a bacteria sample.

Watch our video to see how to use agar and petri dishes, or click for our illustrated bacteria project guide!
