Testing for bacteria (germs) can be a great idea for a science fair experiment since there are so many possibilities for science questions, and because because carrying out the experiment is pretty easy using bacteria growing kits, (and yes, we have them at the Science Bob Store.)
This project shows you one method of measuring the effectiveness of an antimicrobial agent against bacteria grown in culture. This is called the Kirby-Bauer disk-diffusion method, and here is how it works. The bacteria of interest is swabbed uniformly across a culture plate.
Experiment #1: Cheek Cell Swab. Experiment #2: Testing Antibacterial Agents. Experiment #3: Soap Survey. Experiment #4: Bacteria in the Air. Experiment #5: Homemade Yogurt. More Experiment Ideas. Bacteria Overview. Bacteria are one-celled, or unicellular, microorganisms.
Ideally, it will disrupt microbial growth while at the same time preserving most of the nutritional value of the food. To do this project, you should first do background research on methods of food preservation. Then, select an antimicrobial preservation method to test for your experiment.
The objective of this experiment is to learn how to grow bacteria in a controlled setting. By using simple materials from home instead of Petri dishes students will learn how to perform sterile technique.
In this science fair project, you will investigate what kind of bacteria, and how much bacteria, grows in different locations around your home. Bacteria can be both pathogenic, responsible for a variety of diseases, and non-pathogenic, or harmless.
The science fair experiment described here asks, “Are bacteria present in our mouths?”. Using adult supervision, this is an excellent addition to any 4th grade class or higher studying biological science or microbiology. Grow bacteria for the science fair with the tutorial below.
