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

Do Video Game Players Have Faster Reaction Times Than Non-Players?

Science Fair Project Idea

Scientific Method

When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

Effect of Friction on Objects in Motion

Science Fair Project Idea

Scientific Method

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. 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.

Germ Invasion

Science Fair Project Idea

Scientific Method

Microbes are everywhere in our environment, but for the most part they escape our notice. This project shows you how to safely culture and study common bacteria from your everyday surroundings. Read more

Do you enjoy ice-cold drinks? A slushy is about as close as you can get to liquid ice: colder than water, but more drinkable than ice! Using some common household items, a little bit of patience, and the help of science, you can make this delicious, sweet drink at home. Try the activity, and you will be rewarded with a delightful treat! Read more

Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size? Read more

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more
