Death Rays: What Duration of Ultraviolet Exposure Kills Bacteria?

Science Fair Project Idea

Scientific Method

Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for a bacterial cell? Read more

Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

The Tree of Life — I (basic)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use a Web-based… Read more

Testing the Hydrating Power of Hydrogel Face Masks

Science Fair Project Idea

Scientific Method

Do you care about the look and feel of your skin? Then you probably know that your skin prefers to be well hydrated (moisturized). Dry skin often cracks, gets inflamed easily, and looks dull. If you go to the store, you will find many skin care products that promise to hydrate your skin. Among them are cosmetic face masks (sometimes called facial masks) that you put on your face to provide the skin with water and nutrients. In this science project, you will make your own hydrogel face masks… 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

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

BLASTing Flu Viruses

Science Fair Project Idea

Scientific Method

Remember going to the doctor and getting vaccine shots? It is no fun getting poked with a needle, but fortunately, a vaccine helps our immune system to develop protection against a serious illness for years to come. But what about the flu vaccine? How come there is a new one every year? This science fair project will show you why. Read more

Use Machine Learning to Identify Lyme Disease-Transmitting Ticks

Science Fair Project Idea

Engineering Design Process

Ticks are a growing public health concern in North America, as their populations and the diseases they carry, like Lyme disease, are on the rise. But how can we help people identify the ticks they encounter to reduce their risk of infection? With artificial intelligence! In this project, you will gather image data of three different tick species and use a convolutional neural network (CNN) to classify them. You will also apply image augmentation techniques to expand and enhance the dataset,… Read more

Picture This: Building a Cell Phone Microscope

Science Fair Project Idea

Scientific Method

Imagine you are on a trip and see something interesting that you want to share with your friends. What do you do? You take a picture with your cell phone and e-mail it to them, of course. But did you realize that the same technology can be used to save lives? Using their cell phones modified as inexpensive microscopes, medical personnel can look at blood smears to help diagnose diseases like malaria and cholera. In this photography science project you will build a simple and inexpensive cell… Read more

Can Video Games Be a Form of Exercise?

Science Fair Project Idea

Scientific Method

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more
