Science Fair Project Idea

Scientific Method

The Stroop effect describes an experiment about the time it takes to name the color of printed words. When you try to name the color in which color words are printed, it takes longer when the color word differs from the ink color than when the color word is the same as the ink color. This project is an interesting variation: what happens if you 'warp' the words into a curved shape that is harder to recognize as a word? Will the Stroop effect still happen? How 'warped' do the words have to be in… 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

Build a Model Planetary Lander with Arduino

Science Fair Project Idea

Engineering Design Process

Imagine that you need to make sure valuable cargo — like a robot or even human astronauts — can land safely on Mars. How would you do it? In this project, you will build your own model planetary lander using an Arduino. It will use a distance sensor and automatically deploy landing gear before impact. Can you avoid a crash landing?

The Point of a Parabola: Focusing Signals for a Better Wireless Network

Science Fair Project Idea

Scientific Method

Have you ever been annoyed by poor Wi-Fi reception for your phone, tablet, or laptop? Do you wish there was something you could do about it? In this project you will learn how to build a parabolic reflector that you can attach to the antenna of a regular wireless router to help boost its signal. Read more

Make Your Own pH Paper

Science Fair Project Idea

Scientific Method

This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. 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.

Upcycle Paper Products into Plantable Seed Paper

Science Fair Project Idea

Scientific Method

Do you ever have notebooks and papers left over from the school year? Do you recycle them? What if you could use them to start your garden instead? In this science project, you will upcycle old paper into seed cards and test how paper compares to other materials as a fertilizer! Read more

What's Going On Behind Those Puppy-Dog Eyes?

Science Fair Project Idea

Scientific Method

Have you ever wondered what goes on in your dog's mind? Even though humans have the benefit of language, trying to understand another person's thoughts can be hard enough sometimes. Your dog can't talk, so how can you find out what its brain is capable of? The obvious answer is to study its behavior. This project will show you some behavioral tests you can use to measure canine I.Q. Read more

Can Humans Recognize AI-Generated Images?

Science Fair Project Idea

Scientific Method

Can you tell if the pictures on this page are real or generated by a computer? Artificial intelligence (AI) generated images have exploded in popularity, bringing plenty of controversy along with them. An AI-generated image of a tiger or a flower might seem harmless, but artificial images of people or events can contribute to "fake news." In this science project you will investigate whether people can tell the difference between real pictures and pictures generated by AI. Can you spot the… Read more

The Dynamics of a Bouncing Ball

Science Fair Project Idea

Scientific Method

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more
