DNA Fingerprinting

Science Fair Project Idea

Scientific Method

Are you interested in the technical and ethical aspects of genetic screening, forensic science, and DNA fingerprinting? Scientists use different forms of a gene, called alleles, to differentiate between two fingerprints. One such sequence used in human DNA fingerprinting is the Alu repeat (a 300 base pair repetitive sequence of DNA) on chromosome 16. During evolutionary time, up to 1 million copies of the Alu repeat have become randomly inserted throughout the human genome. Within a specific… Read more

The Milky Way and Beyond: Globular Clusters

Science Fair Project Idea

Scientific Method

Globular clusters, compact groups of about a million stars that move around together in galaxies, are among the oldest objects found in the universe. Since they are found in most galaxies and since they've been around for so long, globular clusters have a lot to tell us about what the universe looks like now and how it got that way. Is our Milky Way Galaxy just like all the other galaxies out there? What are galaxies made of? What can we learn about the universe from looking at galaxies? … Read more

Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter

Science Fair Project Idea

Scientific Method

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more

How Direct Reprogramming Can Transform One Type of Cell Straight into Another

Science Fair Project Idea

Scientific Method

In the first decade of the 21st century, scientists found ways to make one adult cell type turn into a completely different cell type. This has huge implications for the medical field, including being able to take some cells that a person could spare, such as skin cells or blood cells, and turn them into another cell type that might be much more important for that person to have, such as cells to make a new kidney. How are scientists able to accomplish this amazing feat of "reprogramming" the… Read more

Rubber Bands for Energy

Science Fair Project Idea

Scientific Method

If you have ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! But just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Read more

Less Cowbell! The Unconstrained Truth About Constrained-Layer Damping

Science Fair Project Idea

Scientific Method

Noise is everywhere. From the clanking of a cowbell to the din of the lunchroom, we are surrounded by noise. Sometimes there's no way to get away from it, but there is a way to deal with it—constrained-layer damping. By simply creating a layered sandwich of somewhat flexible materials, what was once a noisy cowbell can become a "noise blanket." This science fair project shows you how to transform a noisy piece of metal into a sound-muffling constrained-layer damper. You'll record the… Read more

How Sailboats Stay Upright

Science Fair Project Idea

Scientific Method

Have you ever seen a tall sailboat and wondered how they don't flip over when it's windy? Try this project and learn about the physics behind how sailboats stay upright. Read more

Hit the Slopes: Build Your Own Ski Lift

Science Fair Project Idea

Engineering Design Process

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

Simulating The Kessler Syndrome: How Satellite Collisions Could Spiral Out of Control

Science Fair Project Idea

Engineering Design Process

What happens when a satellite collision in space leads to a chain reaction of more collisions? This project models The Kessler Syndrome: A scenario in which collisions between satellites in low Earth orbit create increasing amounts of debris, eventually making the region too dangerous for satellites or spacecraft to operate safely. By adjusting key variables like collision rates and debris generation, you can visualize how quickly space around Earth could become overcrowded, and explore… Read more

Excess Volume: Investigate the "Shrinking Liquids" Effect

Science Fair Project Idea

Scientific Method

Cooking, washing, and many industrial processes involve the mixing of liquids. How liquids behave when they are mixed is dependent on many factors. Sometimes, the mixing behavior of liquids can be quite surprising! For example, when you mix 50 mL of one liquid with 50 mL of another liquid, you might not end up with a 100 mL mixture! In this science project, you will explore this phenomenon, which we call the "excess volume" of mixtures. How do you think your mixing volumes will… Read more
