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

- Less Details
Time Required Long (2-4 weeks)
Prerequisites None
Material Availability This science fair project requires access to some laboratory equipment, such as a 37°C incubator, a Bunsen burner, as well as some specialty reagents, which can be ordered online. 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" #]. 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
Antioxidants have become very popular in the news lately for their potential health and anti-aging properties. Antioxidants work by preventing oxidation reactions that produce free-radicals which can cause harm to the body. Try testing different vitamins for antioxidant activity. How do vitamins A, B, C, and E compare? Do some vitamins have more antioxidant activity than others? What are some other sources of antioxidants? Try testing extracts from proposed sources of antioxidants like coffee,… 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
In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Project Idea
thumbnail What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste, like table scraps, agricultural waste, and human and animal waste, is biodegradable. This means, if oxygen is present, it can be broken down by various microorganisms through a process called composting. If oxygen is not present, it can be broken down using… Read more

Project Idea
Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more
