Science Fair Project Idea
thumbnail Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more

thumbnail Here is a riddle for you: name an instrument that you play with your hands but never actually touch. Have you guessed the answer? It is a theremin! This unusual instrument makes sound without anyone touching it. How does a theremin work? It has an antenna that can detect the player's hand nearby, and as they move their hand around the theremin, the sound it makes changes based on the hand's position. In this music science project, you will get to use your own mini theremin to investigate… Read more

thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

thumbnail Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more

thumbnail If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

thumbnail Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more

Have you ever wondered how it's possible to so accurately date ancient artifacts? Geologists, paleontologists, archeologists, and anthropologists use a statistical process like radioactive isotope decay to date objects through a method called radioactive dating (also known as radiometric dating). To learn more about that method, check out the geology science project . In that particular Project Idea, radioactive decay of isotopes is modeled by rolling dice. While that procedure is a great way… Read more

thumbnail If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more
