Make a "Whirlybird" from Paper

Science Fair Project Idea

Scientific Method

Have you ever seen a maple seed twirling as it falls through the air? In this project you will build something that behaves similarly called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out! Read more

Build a Jumping Robot

Science Fair Project Idea

Engineering Design Process

Can you build a robot that hops like a frog? In this engineering project, you will learn how to build a simple robot that uses the energy stored in a stretched rubber band to jump. You will use the engineering design process to try to make your robot jump higher and farther. How far can you make it jump? Read more

How to Make a Dimmer Switch with a Pencil

Science Fair Project Idea

Scientific Method

Dimmer switches let us control the brightness of a light, anywhere from completely off to full brightness. This can be nice when you want to set the brightness "just right," as opposed to a regular light switch that only lets you turn a light on or off. It turns out that you can make a dimmer switch out of an everyday object—a pencil! Try this project to find out how a dimmer switch can control the brightness of a light. Read more

Build an Ultrasonic Levitator

Science Fair Project Idea

Engineering Design Process

It's not magic; it's science! Build your own acoustic levitator to make objects float in midair using invisible sound waves. 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

Rainbow Fire Science Project

Science Fair Project Idea

Scientific Method

Astronomers can figure out what distant stars are made of (in other words, their atomic composition) by measuring what type of light is emitted by the star. In this science project, you can do something similar by observing the color of flames when various chemicals are burned. Read more

Removing Microplastics from Water with Ferrofluids

Science Fair Project Idea

Scientific Method

Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home. 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

Why Does Fruit Turn Brown?

Science Fair Project Idea

Scientific Method

Have you ever wondered why apple slices turn brown once you cut them, or why a yellow banana gets dark spots over time? In this project you will find out why this happens, and how you can keep your apple slices looking fresh! Read more

What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect

Science Fair Project Idea

Scientific Method

Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more
