Use DNA Sequencing to Trace the Blue Whale's Evolutionary Tree

Science Fair Project Idea

Scientific Method

The first land animals took their tentative steps out of the ocean and onto solid ground around 365 million years ago. Over millions of years, these early ancestors developed into tetrapods, including amphibians, reptiles, dinosaurs, birds, and mammals. Then, around 50 million years ago, the reverse process occurred: the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of… Read more

Make an Automatic Braille Display to Help Blind People

Science Fair Project Idea

Engineering Design Process

We take it for granted that computer screens can update the text on their displays. What about braille, the writing system used by blind and visually impaired people? Braille writing usually consists of a series of permanently raised bumps on a surface like a piece of paper or a sign. How can you make these bumps change or "update" to display different text? Find out in this engineering project as you design and build your own refreshable braille display. Read more

Which Orange Juice Has the Most Vitamin C?

Science Fair Project Idea

Scientific Method

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Predict Air Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Air pollution is a growing issue, especially in cities, due to the rise of industrial activities, increased fossil fuel consumption from things like car use, and natural events like wildfires. This pollution is measured by the Air Quality Index (AQI), which shows how clean or polluted the air is. But what if we could predict changes in AQI to help communities plan ahead to protect people who are at risk from air pollution? That’s where machine learning comes in. In this project, you will… 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

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Is It Ripe Yet? Build a Circuit to Detect Ripe Produce

Science Fair Project Idea

Scientific Method

When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

Predicting How Urban Wildfires Will Spread

Science Fair Project Idea

Scientific Method

Urban wildfires can cause devastating loss of life and property. Can we save lives by predicting how and where these fires will spread? What protective measures can we take to save buildings from the fires? In this project you will use a computer model to simulate how wildfires spread in populated areas, and experiment with different protective measures to try and save houses from burning. 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. Read more

What is the Woolly Mammoth's Closest Living Relative?

Science Fair Project Idea

Scientific Method

Woolly mammoths shook the ground of ice-age tundras for millennia, living next to saber tooth tigers and prehistoric man. Although they have been extinct for thousands of years, scientists continue to learn more and more about this mighty animal. Some of the most exciting new research is being produced by looking at DNA extracted from the hair and bones of woolly mammoths entombed in ice. In this genomics science fair project, you will use bioinformatics tools to determine the woolly mammoth's… Read more
