Project Idea
Is it possible to manipulate bacteria to become protein production factories? Can diabetics control blood glucose with insulin produced by bacteria? How cool would it be to take advantage of these microorganism's sophisticated makeup, short doubling times and cheap growth media to mass produce medically and commercially useful proteins? All of these are possible with a few simple genetic manipulations. By the end of this project you would know the basic foundation on which many… Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability This science project requires access to some laboratory equipment, such as a 37°C incubator, as well as some specialty reagents, which can be ordered online. See the Materials and Equipment list for more details.
Cost High ($100 - $150)
Safety This science project involves the use of the bacterium E. coli. Standard microbiology and bacterial safety guidelines should be followed, see the [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] for more details. To maintain a sterile environment, you will be working near a lighted Bunsen burner. Keep all flammables, including hair and clothing, away from the flame.
Project Idea
thumbnail Most people are not aware that the soil around them is a battle scene. The combatants are very small—bacteria on one side and bacteriophage on the other. The bacteriophage (or phage for short) try to pierce the outer coats of the bacteria and inject them with phage DNA. If successful, the DNA will take over the inner machinery of the bacterial cells and force them to make many copies of the phage. After the copies are made, the bacterial cells break apart, releasing new phage that start… Read more

Time Required Long (2-4 weeks)
Prerequisites This is an advanced science project that requires access to a laboratory with a water bath and 37°C incubator. The kit you will use has enough supplies to perform the procedure one time. To repeat the procedure, you should order additional supplies (listed in the Materials and Equipment section), or make your own media and agar plates. Working with a science teacher or other mentor who is familiar with growing bacteria and titering phage would be helpful.
Material Availability You will need to order the bacteria, the phage, and the supplies from an online science supply store. See the Materials and Equipment list for details.
Cost High ($100 - $150)
Safety The bacteria (E. coli B) and the phage (T4r) are not dangerous, but you should follow common-sense safety guidelines and wear gloves and safety goggles when working in the lab. Adult supervision is recommended.
Project Idea
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. Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability You will need to order a UV-sensitive yeast kit online. See the Materials and Equipment list for details. Note: You might have to have the yeast delivered to a school if the company does not deliver to residential addresses.
Cost High ($100 - $150)
Safety Pouring hot agar plates should be done with caution.
Project Idea
thumbnail 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

Project Idea
If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Project Idea
thumbnail Have you ever wondered if a piece of jewelry is real gold or if it's just some ordinary metal alloy? It turns out that some metals have a unique property; even in small amounts, they can be toxic to some organisms, including algae, molds, fungi, and bacteria, although it often takes many hours to see an effect. Can this phenomena, called the oligodynamic effect be used to tell whether or not the gold or silver in a piece of jewelry is real? Do bacteria react differently to pure, plated, and… Read more

To maintain a sterile environment, you will be working near a lighted Bunsen burner. Keep all flammables, including hair and clothing, away from the flame.
Project Idea
thumbnail 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
