Learn How to Disinfect Contaminated Water
Science Fair Project Idea
Scientific Method
Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water. Read more
Rise to the Occasion: Investigating Requirements for Yeast Fermentation
Science Fair Project Idea
Scientific Method
Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow. Read more
Tiny Titans: Can Silver Nanoparticles Neutralize E. coli Bacteria?
Science Fair Project Idea
Scientific Method
Have you ever heard that nanoparticles can kill bacteria? You may have even seen some consumer products advertise that they contain antibacterial nanoparticles. A nanometer is one billionth of a meter long. Nanoparticles are usually just a few nanometers in diameter — really, really tiny! So how can something that small kill bacteria which are approximately 700 - 1400 nanometers across? Are they really effective? In this science project you will grow some E. coli bacteria and… Read more
Transforming Bacteria to Make Colored Pigments
Science Fair Project Idea
Scientific Method
Can bacteria be altered to produce life-saving insulin for diabetics? Or change color to indicate the presence of a harmful toxin? Yes, it can! Using biotechnology, scientists work daily on problems like these. It starts with selecting a gene you want bacteria to produce and creating a sequence of DNA that has that gene and a promoter that will help express it at the right time and at the right levels. The next hurdle is actually getting this engineered DNA into the bacteria and… Read more
Death Rays: What Duration of Ultraviolet Exposure Kills Bacteria?
Science Fair Project Idea
Scientific Method
Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for a bacterial cell? Read more
Do Different Dilutions of Disinfectants Affect the Development of Bacterial Resistance?
Science Fair Project Idea
Scientific Method
This is a project that illustrates the process of natural selection in action. You'll need access to a laboratory for working with the bacterial cultures used in this project. Read more
Germ Invasion
Science Fair Project Idea
Scientific Method
Microbes are everywhere in our environment, but for the most part they escape our notice. This project shows you how to safely culture and study common bacteria from your everyday surroundings. Read more
Disinfectants
Science Fair Project Idea
Scientific Method
Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare… Read more
Which Acne Medication Can Really Zap That Zit?
Science Fair Project Idea
Scientific Method
Have you ever wondered where acne comes from and how you can treat it? One major cause of acne is the colonization and infection of clogged pores with bacteria. In this science project, you'll test different acne medications and treatments to determine their effectiveness at killing bacteria. Read more
Antibiotic Resistance
Science Fair Project Idea
Scientific Method
Antibiotics work by destabilizing the metabolism or cellular structure of bacteria, preventing growth, and causing bacteria to die. Some strains of bacteria have mutated and found a way to resist the actions of antibiotics. These are called resistant strains because they resist the actions of available antibiotic treatments. There are many different types of antibiotics that are continually being developed to combat new strains of resistant bacteria. Some antibiotics work better on different… Read more
