Science Fair Project Idea
thumbnail 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

Science Fair 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.
Science Fair Project Idea
thumbnail Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

Safety Use care when using sharp knife to chop apples. Do not drink the juice produced in this experiment.
Science Fair Project Idea
thumbnail Have you ever made your own ice cream? If you have, you probably surrounded the ice cream container with ice and rock salt to get the mixture cold enough to freeze. But why does that work? How does adding salt (or other substances) affect the freezing point of water? Find out with this ice-cold science project. Read more

Material Availability Readily available
Cost Very Low (under $20)
Safety No issues
Science Fair Project Idea
The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! Read more

Time Required Average (6-10 days)
Prerequisites An introductory chemistry class.
Material Availability You will need basic lab equipment, which can be ordered online. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Gloves and safety goggles are required. Oxalic acid is toxic and an irritant. Avoid breathing oxalic acid dust and avoid contact with skin. Ammonia is an irritant. Iodine is also an irritant and stains clothes and skin. Adult supervision is required.
Science Fair Project Idea
thumbnail DNA is what makes you look like you. It contains your body's instructions for your hair and eye color, ear shape, your height, and much, much more. Do other living things also have DNA or is DNA only found in humans? You can answer that question yourself (and have your first look at your own DNA) by doing this project. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability A DNA extraction kit, listed in the Materials tab, is used for this project.
Cost Low ($20 - $50)
Safety Adult help is needed to cut a strawberry. The DNA extraction buffer is harmless if you touch it, but do not taste or swallow it.

Science Fair 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

It also requires several pieces of jewelry, including at least one 14-karat gold piece. See the Materials and Equipment list for more details.
Cost Average ($50 - $100)
Safety This science fair 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. Projects using bacteria may require pre-approval from your science fair's [# Link Name="MicroBio_p026.1" Value="HtmlAnchor" #].
