Gamers: Myth or Man?

Science Fair Project Idea

Scientific Method

Male or female? Fat or skinny? Outgoing or quiet? What is your stereotype of a "gamer"? Do your friends have the same mental picture of gamers? How about your parents? This science fair project will help you examine whether the stereotypes of "gamers" actually matches the reality of who plays video games. Read more

Hurricanes and Climate

Science Fair Project Idea

Scientific Method

The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more

The Case of Mistaken Identity

Science Fair Project Idea

Scientific Method

Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure used in the real-world process of eyewitness identification of criminal suspects: the lineup. How accurate are eyewitness identifications using various lineup methods? Read more

Measuring Vibrational Frequency with Light

Science Fair Project Idea

Scientific Method

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

Zapping Yeast with X-rays

Science Fair Project Idea

Scientific Method

Have you ever wondered how X-rays affect living organisms? You have probably had X-rays taken at the dentist's or doctor's office. These X-rays are considered to be relatively safe, but every X-ray exposes a person to some radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation. When the energy in X-rays encounters an object, it can… Read more

Helmholtz Resonance and Musical Instruments

Science Fair Project Idea

Scientific Method

Helmholtz resonance, or air cavity resonance, refers to the resonance of air in a container with a small opening, like a plastic bottle or the devices shown in Figure 1. The resonant frequency of the air depends on the volume of the air in the container and the geometry of the opening (its length and cross-sectional area). The Helmholtz frequency is not the same as the natural frequency of an air column in a cylinder, where the opening is the same size and shape as the rest of the cylinder. … Read more

Cha-cha-cha by Latitude

Science Fair Project Idea

Scientific Method

You probably know that where you live on Earth affects your weather. If you live in a far northern or far southern latitude, you experience colder temperatures than people who live near the equator at latitudes close to zero. Your latitude on Earth affects many aspects of your culture, like how you dress, what kind of house you live in, what foods you eat, and even how your day is structured: what time you go to school, to dinner, and to sleep. Some cities at latitudes closer to the equator,… Read more

Encryption

Science Fair Project Idea

Scientific Method

Want to send coded messages to your friends? Can you write a simple letter-substitution encryption program in Python or JavaScript? How easy is it to break the simple code? Can you write a second program that "cracks" the letter-substitution code? Investigate other encryption schemes. What types of encryption are least vulnerable to attack? Read more

Antioxidants

Science Fair Project Idea

Scientific Method

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

Factors that Affect the Transfer of Force through Saturated Soil

Science Fair Project Idea

Scientific Method

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding certain materials to… Read more
