Can Machine Learning Forecast Future Sea Levels?

Science Fair Project Idea

Scientific Method

Global sea levels are rising, but modeling and predicting them can be challenging with more and more extreme weather events. Can we use machine learning to track and predict sea level changes? In this science project, you will use previously collected data and machine learning to see if you can predict future relative sea level changes. Read more

Can You Create an Unbeatable Tic-Tac-Toe AI Player?

Science Fair Project Idea

Engineering Design Process

Do you think you can win tic-tac-toe against an AI player? In this project, you will explore how the Minimax algorithm makes decisions in two-player games such as tic-tac-toe. This project requires little to no coding skill; instead, you will need an open mind and curiosity. Why not give it a try yourself? Read more

From Genes to Genetic Diseases: What Kinds of Mutations Matter?

Science Fair Project Idea

Scientific Method

Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.

How Old Is the Universe?

Science Fair Project Idea

Scientific Method

Would it surprise you to learn that no one knows the exact age of the universe? Astronomers have estimates, and as they gather increasingly precise data and measurements, they continue to refine those estimates to come up with more accurate estimates. In this project, you can look at data about stars in dense groups called globular clusters and come up with your own estimate for the minimum age of the universe. How closely will your estimate match those of other astronomers? Read more

NASA Asteroid Database: What Can You Learn About Our Solar System?

Science Fair Project Idea

Scientific Method

Did you know that in addition to the Sun and planets, our solar system is filled with millions of asteroids, which are chunks of rock left over from the early days of its formation, or from collisions between larger objects like planets? Agencies like NASA track asteroids, not only because they might pose a threat to humanity by colliding with Earth, but because they can provide us with information about the history of our solar system, and even be useful for mining raw materials in space! In… Read more

Which Skin Moisturizer Works Best?

Science Fair Project Idea

Scientific Method

Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… Read more

Mixing Your Own Marshmallows: Finding the Right Ratio of Sugar to Corn Syrup

Science Fair Project Idea

Scientific Method

Whether you are sitting around a campfire, or drinking hot chocolate after a day in the snow, nothing says fun quite like a marshmallow! Even its name is soft and spongy! In this cooking and food science fair project, you will make your own marshmallows several different ways, and discover the three special ingredients that give marshmallows their unique texture. You will also find out why they melt so quickly. Explore the science of these sticky, spongy sweets! Read more

Lift a Load Using Hydraulics

Science Fair Project Idea

Scientific Method

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more

Solar-powered Chemistry: Study Chemical Reaction Rates in Ultraviolet Beads

Science Fair Project Idea

Scientific Method

Most of the ultraviolet (UV) light produced by the Sun is blocked by the atmosphere, but some UV light does still reach Earth. It can be detected using electronic devices, but can also be detected with something called UV beads. UV beads contain a pigment that changes color when they are exposed to ultraviolet radiation from the Sun. In this chemistry science fair project, you will use UV beads to study how temperature affects the rate at which they lose their color. Read more

Create a Facial Recognition System with Machine Learning

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your smart devices can recognize and distinguish your face from that of others? In this project, you will explore how to create and modify a facial recognition model using a type of artificial intelligence known as neural networks. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more
