Can AI Classify Stars?

Science Fair Project Idea

Engineering Design Process

Understanding the different types of celestial objects in our galaxy is important for astronomers. It helps them study how these objects form and evolve, map the night sky, understand the structure of the Milky Way and other galaxies, and identify celestial bodies that might host habitable environments. In this project, you will create a boosted tree model to classify celestial objects based on their spectral characteristics. Read more

Crime Scene Chemistry: The Kastle-Meyer Test for Blood

Science Fair Project Idea

Scientific Method

Police detectives use various scientific tools to analyze evidence at a crime scene. One of the classic tools is the Kastle-Meyer test for the presence of blood. This test is inexpensive, easy to perform, and provides quick results. The test provides evidence if red spots found at a crime scene are actually blood. But the investigator needs to be careful, since other substances can also give a positive result. In this crime scene chemistry science project, you will learn how to perform the… Read more

Watching Nuclear Particles: See Background Radiation Zoom Through A Cloud Chamber

Science Fair Project Idea

Scientific Method

Do you realize that you are constantly bombarded by particles? You do not feel them, you cannot see, hear, or smell them, but they are always there! These particles — collectively called background radiation — might even travel through you without ever interacting with the molecules in your body. In this science project, you will build your own cloud chamber to prove the existence of background radiation. You will then use your cloud chamber to determine if the background… Read more

What's The Best Way to Land a Model Rocket?

Science Fair Project Idea

Scientific Method

What's the best way to land a model rocket? What makes the rocket hit the ground safely at a low speed? What prevents the rocket from drifting too far if it's windy? In this project, you will make your own rockets from paper towel tubes and drop them to test different recovery methods like parachutes and streamers. What method do you think will work the best?

Try the Mythbusters' "Phone Book Friction" Experiment at Home

Science Fair Project Idea

Scientific Method

Have you ever heard that two phone books with the pages interleaved are impossible to pull apart? This might seem crazy, right? It is not that hard to slide a sheet of paper off the top of a stack of paper. How much friction can there really be between sheets of paper? In this experiment, you will use pads of sticky notes instead of phone books. How much weight can they support when you interleave the pages? Do you think you will be able to pull them apart by hand? The results might surprise… Read more

Star light, Star bright: How Does Light Intensity Change with Distance?

Science Fair Project Idea

Scientific Method

Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use a sensor app with your smartphone to discover the key relationship between brightness and distance. Read more

Rusting Out: How Acids Affect the Rate of Corrosion

Science Fair Project Idea

Scientific Method

Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. 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

Exploring the Impact of Social Media on Mental Health with Machine Learning

Science Fair Project Idea

Scientific Method

Do you ever wonder if you spend too much time online? How can the amount of time spent on social media influence someone's mental health? What other factors play a role? In this science project, you will investigate which variables correlate with better mental health scores using a machine learning algorithm called the Random Forest algorithm. Read more

Design a Mini Solar Tracker System

Science Fair Project Idea

Engineering Design Process

How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! Read more
