How Bright Is Your Glow Stick? Measure It!

Science Fair Project Idea

Scientific Method

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Ion Thruster: Build an Ion Wind Rotor

Science Fair Project Idea

Scientific Method

Ion thrusters, also called ion engines (Figure 1), are a type of electrically-powered spacecraft propulsion. While they provide very low thrusts (and thus low accelerations), they can do so for very long periods of time using a very small amount of fuel. So, while not appropriate for escaping Earth's gravity like chemical rockets which are less efficient but generate higher thrusts, they are useful for deep-space probes or making small adjustments to satellite orbits. You can read more about… 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

Motorized Arduino Cable-Driven Spacecraft Motion Simulator

Science Fair Project Idea

Engineering Design Process

How do you practice docking a spacecraft with the International Space Station or landing on Mars? With a room-sized cable-driven spacecraft motion simulator! In this project, you will build your own miniature, motorized version of a full-sized motion simulator scientists are developing that can move model spacecraft around in a controlled manner.

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 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

Crack the Code: Breaking a Caesar Cipher

Science Fair Project Idea

Scientific Method

When you hear the word "encryption," you might think about modern computers and things like email and online bank accounts. But did you know that encryption has been around for thousands of years? In this project you will learn about the Caesar cipher, a simple type of encryption that replaces each letter of the alphabet with another letter, and demonstrate how a modern computer can crack this ancient code in just a few seconds.

A Robot Waiter That Can Carry Drinks

Science Fair Project Idea

Engineering Design Process

Have you ever seen a waiter balance an entire tray of drinks without spilling any? How do they do it? Do you think you could build a robot waiter that can do the same thing? In this project, you will learn how to build a self-balancing robotic tray. You can incorporate the auto-leveling tray into one of our many other robotics projects, like the Bluebot or robotic arm.

Adsorption: Dyeing Fabrics with Kool-Aid

Science Fair Project Idea

Scientific Method

Have you ever wondered how your clothes get their color? Dyeing textiles is a very complicated process and involves a lot of chemistry. Not only are the properties of the dye and fabric important, but the dyeing conditions also have to be exactly right to get optimal color adsorption. Curious about how it works? In this science project, you will color wool with Kool-Aid® and explore the chemistry of dyeing. Read more

Control Motors with Your Muscles!

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could control your own suit of power armor like Iron Man? What about building a set of Wolverine-like retractable claws? You can get started by using electromyography (EMG) sensors, which can measure the tiny electrical signals generated by our muscles when they contract (Figure 1). You can interface these sensors with a microcontroller like an Arduino and use the output to control LEDs or motors. Getting these sensors to work can be tricky. The electrical signals… Read more
