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.
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…
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.
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…
Do you know what is living in your backyard? How about at the playground, or in your compost pile? Nematodes, also called roundworms, are the most abundant animal on Earth and they might be living in any of these places. In this science project you'll isolate nematodes from several soil samples to discover the best nematode habitats.
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.

Many scientists are currently very excited about CRISPR, as it has the potential to revolutionize gene editing. But what exactly is CRISPR and what does it do? CRISPR is a novel tool in gene editing that allows the modification of genetic DNA at specific target sites in many different organisms. Researchers have high hopes that this technology can, one day, cure genetic diseases, as mutated DNA sequences can easily be corrected. In this project, you will use CRISPR to mutate a DNA sequence…
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 project uses liquid cultures and agar plates to investigate the effects of different concentrations of a food preservative on microbial growth.

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.
