Marble Roller Coaster: How Much Height to Loop the Loop?

Science Fair Project Idea

Scientific Method

This is a really fun project even if you don't like going on roller coasters yourself. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much of an initial drop is required to get the marble to "loop the loop." It's a great way to learn about how stored energy (potential energy) is converted into the energy of motion (kinetic energy). Read more

How Old Is That Rock? Roll the Dice & Use Radiometric Dating to Find Out

Science Fair Project Idea

Scientific Method

What do rocks and clocks have in common? Both keep track of time. Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away. Geologists use those radioactive isotopes to date volcanic ash or granite formations like the giant Half Dome in Yosemite National Park. Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. Does this sound abstract and… 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 Effect of Bridge Design on Weight Bearing Capacity

Science Fair Project Idea

Scientific Method

Build model bridges and then deliberately destroy them? Who'd be crazy enough to try that? 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

Parachutes: Does Size Matter?

Science Fair Project Idea

Scientific Method

How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project if the size of the parachute matters. Read more

Identify Road Signs with Machine Learning

Science Fair Project Idea

Engineering Design Process

Driverless cars use machine learning, a type of artificial intelligence, to identify road signs and other things they encounter on the road, like pedestrians and other vehicles. In this project you will take your own pictures of different types of road signs and use machine learning to identify the signs using a free online tool (no programming is required). You will then attempt to improve your machine learning model so it can identify signs in a variety of environments. 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

Supercooling Water and Snap Freezing

Science Fair Project Idea

Scientific Method

Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be supercooled. Read more

Bottle Rocket Blast Off!

Science Fair Project Idea

Scientific Method

3... 2... 1... 0— blastoff! In this science project, you will use a bottle rocket launcher to launch your own bottle rocket. You will load it with water and pressurized air, make several launches, and find out what makes your rocket soar the highest. Read more
