Build Your Own Crystal Radio

Science Fair Project Idea

Scientific Method

Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. 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

Scintillating Scents: The Science of Making Perfume

Science Fair Project Idea

Scientific Method

Have you ever watched your parents dress up for a big evening? They may even splash on a bit of aftershave cologne or dab on some perfume since it is special occasion. But did you know that using perfume and scents is an ancient activity? Perfumes and the art of making perfume is an art that is thousands of years old. In this chemistry science fair project, you will learn more about one way to make perfume, called enfleurage, and experiment with it to extract your own floral scents. Read more

Have you ever seen a helicopter flying through the air? Have you ever wondered how they fly—or if you could try flying one yourself? This fun activity will help you get started at home building a simple paper helicopter. And you will learn a little bit about what keeps these amazing vehicles aloft. Read more

Solar-Powered Water Desalination

Science Fair Project Idea

Scientific Method

How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

Use a Microbial Fuel Cell to Create Electricity from Waste

Science Fair Project Idea

Scientific Method

"Gross! What is that in the toilet?" But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair project, you will make a microbial fuel cell to collect the electrons that the bacteria—anaerobic bacteria—create...only, you'll be using mud, which is much safer to handle than wastewater. If you would like to learn how to reuse and recycle an… Read more

Are Fingerprint Patterns Inherited?

Science Fair Project Idea

Scientific Method

Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?… Read more

Build a Model Satellite with Arduino

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how satellites steer themselves? How can a spy satellite aim its camera? How can a satellite keep its solar panels oriented toward the sun? In this project, you will learn about one method satellites use to control their orientation, called a reaction wheel, and build your own working prototype of a miniature satellite. Read more

Can Humans Recognize AI-Generated Text?

Science Fair Project Idea

Scientific Method

AI (artificial intelligence)-generated text is a hot topic for many reasons. Computers can now generate convincing paragraphs or even pages of text that look like they were written by a human. How do you know if a news article you are reading was written by a human or an AI? How does a teacher know if a student's essay was written by an AI? How do you know this text was not written by an AI? In this science project, you will conduct an experiment to see if volunteers can correctly identify… Read more
