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.

How Blue is Your Sports Drink?

Science Fair Project Idea

Scientific Method

Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring… Read more

Hacking the Air Gap: Stealing Data from a Computer that isn't Connected to the Internet

Science Fair Project Idea

Scientific Method

You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby… Read more

Minds of Their Own: A Chemical Reaction that Changes, then Changes Back!

Science Fair Project Idea

Scientific Method

Have you ever seen a chemical reaction that makes a solution change color? Probably. But what about a solution that changes color and then changes back, not only once, but many times? Sounds pretty exotic! Whereas most chemical reactions only move in one direction from reactants (starting chemicals) to products, in these rare oscillating reactions, the reaction products appear and disappear for a number of cycles. Because the products are colored, the solution appears alternately blue, then… Read more

Bioinformatics - The Perfect Marriage of Computer Science & Medicine

Science Fair Project Idea

Scientific Method

Find out the real explanation for why your parents are so weird! Here is a science project that lets you explore the internet to find out why your "DNA blueprint" is so important to health and disease. In this science project, you will use methods that bioinformatics and biotech scientists perform on a daily basis to decipher the human genome in their efforts to diagnose and treat genetic diseases.

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

Build Your Own Radon Detector

Science Fair Project Idea

Scientific Method

Electronic devices can be designed to detect dangerous fumes or other hazards, such as smoke or carbon monoxide. In this electronics project, you will build another potentially life-saving detector—a radon detector. Radon gas is radioactive and can pose a hazard to your health if you live in an area where it leaks from the ground. In this electronics science project, you will learn how to collect radon with an ordinary dusting cloth mounted on the intake of a fan, and then measure its… Read more

Build a Model Mass Driver for Launching Objects into Space

Science Fair Project Idea

Scientific Method

A mass driver uses electromagnetics to launch projectiles. In the future, such a device could launch payloads into space without the use of chemical rockets. This could lead to long-term cost savings when launching large amounts of material into space—for example, to construct a space station. In this project you will design and build your own working model mass driver as you learn some of the engineering principles behind how mass drivers operate. 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

Computational Exploration of Protein Function

Science Fair Project Idea

Scientific Method

The DNA in our cells contains our "blueprints," but it's the proteins in our cells that do most of the work. The Human Genome Project has allowed us to start reading the blueprints, but we still don't understand what most of the proteins do. This is a fairly advanced project that explores ways of identifying the function of unknown proteins. Read more
