Do Antibiotics Change Your Gut Microbiome?

Science Fair Project Idea

Scientific Method

There are thousands of bacteria in your gut that help you digest your food, recover important nutrients, and maintain your health. What happens to those bacteria when you take antibiotics? In this science project you will find out by accessing and analyzing a real data set of the gut microbiome (bacteria and other microbes) from healthy adults before and after they are given antibiotics.

The Case of Mistaken Identity

Science Fair Project Idea

Scientific Method

Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure used in the real-world process of eyewitness identification of criminal suspects: the lineup. How accurate are eyewitness identifications using various lineup methods? 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

Is There Such a Thing as Streakiness in Baseball?

Science Fair Project Idea

Scientific Method

Here's a project that will teach you about math as you follow some of your favorite players or teams. You'll be comparing day-to-day performance with long-term averages, and trying to determine if the "streaks" and "slumps" over shorter time periods are due to random chance or something else. When you've finished, you'll have a better understanding of some important concepts in statistical analysis and baseball. If a player goes 0-for-20, does that mean anything? Using probability theory,… Read more

Plants on the Move! Experiments with Phototropism

Science Fair Project Idea

Scientific Method

Plants move—not very quickly compared to animals, but they do move. Their roots grow downward in response to gravity, and their stems grow upward toward the Sun. In this plant biology science fair project, you will investigate how young plants respond through movement to light. Read more

Testing the Accuracy of Eyewitness Testimony

Science Fair Project Idea

Scientific Method

Think back to the last time you went to the grocery store. How well can you describe the person who was ahead of you in the check-out line? How many details do you remember about the person? How accurate do you think your memory is? Here is a project to investigate the accuracy of people's observations during everyday life. Read more

Tee Time: How Does Tee Height Affect Driving Distance?

Science Fair Project Idea

Scientific Method

If you're an avid golfer, this might be a fun project for you. When you're setting up to tee off out on the course, how much attention do you pay to putting the tee in the ground? The height of the tee can affect both where in the swing the club makes contact and where on the clubface the ball makes contact. Are you placing your tees at the right height to get the most distance from your swing? Read more

What is the Maximum Intermediate Height for a Siphon?

Science Fair Project Idea

Scientific Method

A siphon is a handy device for emptying out a liquid reservoir that has no drain. For example, they're great for cleaning fish tanks. An interesting aspect of a siphon in action is that the liquid flows "uphill" for a portion of its journey through the tube. This project asks the question, is there a maximum height for that uphill part of the siphon? Read more

Using a Laser to Measure the Speed of Light in Gelatin

Science Fair Project Idea

Scientific Method

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

Testing How Clothing Choices Impact the Behavior of Others Around Us

Science Fair Project Idea

Scientific Method

Do people treat someone differently based on his or her appearance? Specifically, how are their behaviors affected by the clothes a person wears? For instance, if somebody wears a formal suit, do you think others behave differently when interacting with that person compared to if he or she were wearing casual clothes, like blue jeans? In this science project, you will get to try and find out! Read more
