Middle School Microbiology Science Projects (7 results)

Microorganisms are all around us, with an amazing diversity of adaptations. They were the first life on Earth, and their relatively recent discovery in extreme environments—like hot springs, ocean vents, and polar ice—illustrates how tenaciously they've evolved and survived. Microbiology gives us insights into evolution, disease, and even the mechanisms of our own cells. Explore our collection of microbiology projects to learn more about these tiny and amazing organisms.

Science Fair Project Idea
There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Science Fair Project Idea
Bacteria are powerful little creatures. They can dispose of contaminants, make us sick and did you know they can even generate electricity? In devices, called microbial fuel cells (MFC) they can extract electrons from their food sources such as organic materials and feed them into an electrical circuit to generate power. This way they can even turn plain soil into a source of energy! Does it matter though what kind of food the bacteria "eat"? Find out how bacteria grow in a microbial fuel cell… Read more

Time Required Very Long (1+ months)
Prerequisites Previous experience using a multimeter and familiarity with the physics of electricity is helpful, but not required. A basic knowledge of how to work with bacteria is also recommended to complete this science fair project. Consult the [# ProjectGuide Name="Advanced.MicrobiologyTechniquesampTroubleshooting" Value="HtmlAnchor" HtmlText="Microbiology Techniques and Troubleshooting" #] guide for information on how to conduct microbiology experiments.
Material Availability The needs to be special ordered from our partner .
Cost Very High (over $150)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics or power plugs, or have their fibers dispersed in the air. Use sterile technique when growing the bacteria. Read the before starting any experiments. may be necessary. Adult supervision is recommended.
Science Fair Project Idea
Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more
