Science Fair Project Idea
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

Have you ever wondered how virtual reality works? With virtual reality, people feel like they are in one place while knowing they are somewhere else. In this project, you will show the same phenomenon on a smaller scale. You will use the McGurk effect to show how you can hear one sound, while knowing a different sound is physically there. First, you will produce such an experience using audio and video, and then measure the strength of the phenomenon. Read more

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

Are you convinced that virtual reality (VR) will soon become mainstream and improve our lives in unpredicted ways? Or maybe you believe it is a big hype doomed to fade and disappear. In this science project, you will use one aspect of VR—the headset—and investigate if it could convey reality better than traditional pictures or 360° images. You will go out and measure how people perceive pictures and images you took. Will people embrace the VR headset and what it can do, or… Read more

Take a deep breath: freshly baked cookies, smoke from a wood fire, or a rose—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling the hints of smoke from the grill far away. How strong or weak you perceive an odor depends on its concentration. What do you think is the lowest concentration of a… Read more

Social media is all the buzz on the internet. What can we do with all the information generated by millions of people posting, tweeting, taking pictures, and chatting? How do companies convert it into profit? While you do not have the tools to analyze data from millions of social media posts by yourself, you will be able to analyze a scaled-down version. Follow the instructions in this project to try your hand at extracting data from a couple of social media sites and use it to create… Read more

"Paper circuits" are a fun way to mix electronics and art by adding lights directly to a painting or drawing. These lights need a battery to power them, and typically you would use wires to connect them. In paper circuits, though, many materials can be substituted as "wire," including special types of paint, ink, and even aluminum foil. There are also different options for what type of battery you can use. Which materials do you think will work best? Try this project to find out! Read more

Passports, identification cards, bus passes, and even some credit cards contain RFID tags. An RFID (radio-frequency identification) tag allows a card to be read by a computer from a short distance away. While this is very useful in everyday life, would you believe you can make music with it? RFID + sampled music sounds + a little crafting = a fun musical instrument that is limited only by your imagination. In this science project, you will make handbells out of paper cups that play real sounds,… Read more
