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.)
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.
3 Μαΐ 2021 · Germs and bacteria are all around us and make a great topic for science projects. Bacteria growth kits are inexpensive and readily available for kids. With a good hypothesis and the correct format, bacteria experiments can make impressive winning science fair projects.
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.

Growing bacteria, or other microorganisms, on agar plates is a common step in microbiology experiments. There are two methods for inoculating (putting the bacteria on) agar plates: quadrant streaking and spread plating. Which one you choose depends on what you want to do after.
Different types of agar are used for growing different strains of bacteria. Generally, an experimental procedure will tell you what type of agar to use. If you are still unsure, ask a teacher or consult our Ask An Expert forum. Not all types of agar are good for students to use unsupervised at home.
