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

Ozone Depletion

Science Fair Project Idea

Scientific Method

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… 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

How Vines Find Their Spines: Thigmotropism in Morning Glory Tendrils

Science Fair Project Idea

Scientific Method

We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project, you will investigate how plant tendrils respond to touch stimuli. Read more

Do Oranges Lose or Gain Vitamin C After Being Picked?

Science Fair Project Idea

Scientific Method

Are oranges highest in vitamin C when they are fresh from the tree (or, in a pinch, the grocery shelf)? Does the amount of vitamin C in an orange change over time, after it has been picked? In this science project, you will find answers to these questions by measuring the amount of vitamin C in a solution using an iodine titration method. Read more

Tracking COVID-19's Genomic and Clinical Evolution

Science Fair Project Idea

Scientific Method

Over time, viruses evolve. Their evolution is influenced by both neutral drift, the natural mutation rate of the virus, and selective pressure from the hosts' immune systems. Scientists study a virus's genomic evolution—the changes at the nucleotide and amino acid level—to better understand how the virus is spreading and the clinical implications. You can use public databases and tools to do the same type of tracking and analysis of COVID-19 that scientists around the world do. … Read more

Predicting the Weather

Science Fair Project Idea

Scientific Method

Before you head for school for the day, you might check the weather to see whether or not you need to wear a jacket or bring an umbrella. It is pretty easy for you to check the TV or internet to see what the weather will be like today, tomorrow, or even next week. The modern-day science of meteorology, or studying and predicting the weather, has many advanced tools at its disposal that make it easy for you to get this information. How did people predict the weather before the invention of… Read more

How Do You Get Heat from a Supercooled Solution? Explore the Chemistry Within Hand Warmers

Science Fair Project Idea

Scientific Method

You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… 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. Read more

Can You Create a Strategic Connect 4 AI Opponent?

Science Fair Project Idea

Engineering Design Process

When you play Connect 4, what strategies do you use to increase your chances of winning? In this project, you will explore how artificial intelligence can make decisions in two-player games such as Connect 4. This project requires little to no coding skill. Instead, you will need patience and an open mind. Why not give it a try yourself? Read more
