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…
Have you ever heard or read about GMO?
GMO stands for
genetically modified
organisms.
Scientists can deliberately modify the DNA of organisms, such as bacteria or plants, to change their properties for a specific purpose. For example, crops can be modified to become more drought- or pest-resistant. Genetic engineering is a very powerful tool in biotechnology that has already found many different applications in agriculture, medicine, and industry. In this project, you will engineer a…
Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired.

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…
How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.
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.

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.
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.
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.
Germs are everywhere! We try and clean our home with disinfectants, but do we really get rid of all the germs? Find out with this "hands-on" experiment.
