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

- 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.

You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What… Read more

thumbnail Today magnetic recording is used in audio and video cassette recorders, and computer disk drives. Did you know that you can also use an electromagnet to record and play back from a steel wire? In fact, this is how magnetic recording got started. This project shows you how to build a simple wire recorder. Read more

thumbnail The sun sometimes releases huge bursts of electrified gases into space. These bursts are called coronal mass ejections (or CMEs). When CMEs are directed towards Earth they can generate auroras, the spectacular atmospheric displays also known as "northern lights" (photo by Chris VenHaus, 2001). In this project you'll use images from the SOHO satellite to measure how fast CMEs move. Read more

Winglets are the short vertical "fins" at the wingtips of some airplanes. Have you ever wondered why they are there? If you have access to a wind tunnel, you can build model airfoils with and without winglets and see for yourself. If you're really ambitious, you can also build your own wind tunnel. Read more

thumbnail If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.

thumbnail 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… Read more

thumbnail Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. Read more

thumbnail Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more
