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

Can AI Diagnose Breast Cancer?

Science Fair Project Idea

Scientific Method

Getting started with machine learning is like unlocking a new world of possibilities, and the best part is that you don't need to be a computer genius to do it! In this project, you will create a K-Nearest Neighbors (KNN) machine learning model that can predict whether a patient has a benign tumor or malignant breast cancer based on the characteristics of the tumor cell nucleus, such as its radius, perimeter, area, and smoothness.

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

Measuring the Speed of 'Light' with a Microwave Oven

Science Fair Project Idea

Scientific Method

Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland. 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

Sucrose & Glucose & Fructose, Oh My! Uncovering Hidden Sugar in Your Food

Science Fair Project Idea

Scientific Method

Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars—glucose and sucrose—in different foods, and investigate how sucrose is converted into glucose with the help of an… 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 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

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

Exploring DNA Damage: What Effect Do Ultraviolet Rays Have on Yeast Colony Growth?

Science Fair Project Idea

Scientific Method

Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired. Read more
