Password Security: How Easily Can Your Password Be Hacked?

Science Fair Project Idea

Scientific Method

We use passwords every day for our email and other computer accounts. How secure is the password that you use? How hard would it be for someone to guess your password? How hard is it to write a computer program to guess a password? You can see for yourself by writing a simple password guesser in the computer language Python. We will get you started with some ideas, a little sample code, and a few passwords for your computer program to try and guess. Read more

Can You Influence the Compromise Effect of Decision Making?

Science Fair Project Idea

Scientific Method

Have you ever given any thought to the question, "What size drink do you want?" This experiment explores the behavioral neuroscience behind decision-making. It will explore why we make certain choices and even how we rationalize our choices after we make them. Read more

Absorption of Radiant Energy by Different Colors

Science Fair Project Idea

Scientific Method

Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

Build a Sound-Tracking Search and Rescue Robot

Science Fair Project Idea

Engineering Design Process

HELP! Locating survivors trapped under rubble is a difficult and dangerous task. After a natural disaster, like an earthquake, rescuers must act quickly to save as many lives as possible. They can use robots with different types of sensors to help find survivors. In this project you will build a sound-tracking robot that can use two microphones to drive toward a sound source. Designing the robot's algorithm will be up to you. Read more

Build an 'Impossible' Wind-Powered Car

Science Fair Project Idea

Engineering Design Process

Is it possible for an entirely wind-powered vehicle to travel directly downwind faster than the wind? This might seem counterintuitive or like it would violate the law of conservation of energy. After all, any good scientist knows that perpetual motion machines are impossible. However, as demonstrated by YouTubers Rick Cavallaro, Derek Muller (Veritasium), and Xyla Foxlin, you can take advantage of some tricky physics to make this vehicle work. Can you build—or even improve—your own… Read more

Build a Magnetic Pet Door

Science Fair Project Idea

Engineering Design Process

Does your home have any pet doors or gates for dogs, cats, or other animals? Some automatic pet doors can be set up to allow only certain animals through. These doors can help you control which pets are able to go outside alone or which ones have access to specific food, litter boxes, or toys. But why buy such a door when you can make one? In this project you will build your own automatic pet door that works with a magnetic collar tag. Exactly how you use it is up to you! Read more

Use a Microbial Fuel Cell to Create Electricity from Waste

Science Fair Project Idea

Scientific Method

"Gross! What is that in the toilet?" But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair project, you will make a microbial fuel cell to collect the electrons that the bacteria—anaerobic bacteria—create...only, you'll be using mud, which is much safer to handle than wastewater. If you would like to learn how to reuse and recycle an… Read more

Make Soft Robotic Skin

Science Fair Project Idea

Engineering Design Process

When you think about robots, do you think of something made from metal? What if robots could have stretchy, flexible skin just like humans? How would they detect when someone tapped them on the shoulder or something rubbed against their arm? In this project, you will learn how to make artificial robotic skin using flexible rubber with an embedded conductive fabric. You can also connect the artificial skin to a microcontroller and use it to control outputs like LEDs or motors. Read more

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. Read more

See Air Currents with Shadowgraphs and Schlieren Images

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more
