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

Using the Solar & Heliospheric Observatory Satellite (SOHO) to Measure the Motion of a Coronal Mass Ejection

Science Fair Project Idea

Scientific Method

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

Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ

Science Fair Project Idea

Scientific Method

The human kidney is the most commonly transplanted organ in the United States, numbering more than 17,000 transplants in 2010 alone! But kidney transplantation technology faces a lot of challenges, including a shortage of kidney donors and the need for recipients to take immunosuppressant drugs to keep their bodies from rejecting a transplanted kidney. In this science project, with the help of bioinformatics databases, you will explore how a kidney could be bioengineered using stem cells,… Read more

The Science & Reflexes of Dizziness

Science Fair Project Idea

Scientific Method

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!

Solid Ground? Measuring Soil Bearing Capacity

Science Fair Project Idea

Scientific Method

Foundations for many types of structures rest on soil. This project shows how you can investigate the bearing capacity of different types of soil. Read more

Make Your Own Piezoelectric Pickup for Acoustic Guitar

Science Fair Project Idea

Scientific Method

In this project you'll learn how to make a piezoelectric pickup for acoustic guitar using inexpensive components. You can then connect your acoustic guitar to an amplifier, and record your own music. If you are interested in electronics and like playing acoustic guitar, this could be the perfect project for you. Read more

Using a Laser to Measure the Speed of Light in Gelatin

Science Fair Project Idea

Scientific Method

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

The Joly Photometer: Measuring Light Intensity Using the Inverse Square Law

Science Fair Project Idea

Scientific Method

You have probably seen light bulbs with different wattages, for example 50 W or 100 W. Higher-wattage lights are brighter but they also consume more electrical power. Are some bulbs more efficient than others, meaning they produce more light per unit of electrical power? You can find out for yourself by making a simple photometer to compare the light output from different bulbs. This project shows you how. Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

The Leaning Tower of Pasta

Science Fair Project Idea

Scientific Method

Here's a project for a budding architect or structural engineer. Can you make a strong, lightweight tower using only uncooked spaghetti and white glue? In this project, you'll learn about materials testing and apply what you learn to building and testing structures that are both strong and light. Read more
