Science Fair Project Idea

Scientific Method

Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you will choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more

Do People Prefer Virtual Reality Headsets over 2D Pictures?

Science Fair Project Idea

Scientific Method

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

Do Stress Management Techniques Work for Different Types of Stressors?

Science Fair Project Idea

Scientific Method

Have you ever noticed that your heart beats faster when you’re nervous before a big event? How and when does your heart rate slow down back to normal? In this science experiment, you will see if you can use different stress reduction techniques (meditation, yoga, breathing techniques) to determine which type works best for different kinds and intensities of stressors (physical or mental). You can also record other physiological measures, such as blood oxygen and blood pressure, to see how… Read more

Do You Have the Willpower to Taste Something Sour?

Science Fair Project Idea

Scientific Method

If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults? In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them! Read more

Have you ever noticed that some people are a lot pickier about the food they eat than other people are? They might be more selective because they are supertasters! To supertasters, the flavors of foods are much stronger than to average tasters. Whether or not someone is a supertaster comes down to the taste buds on his or her tongue, and you can actually investigate a person's supertaster status by looking at this. Are you a supertaster? Find out with this tongue-based activity! Read more

Does Body Size Matter?

Science Fair Project Idea

Scientific Method

Animals come in all shapes and sizes, even humans. You can look up different statistics about different kinds of animals using the Internet: average body size, brain size, life expectancy and generation time are some examples. Is there a correlation between body size and life span? Is there a correlation between body size and brain size? Is there a correlation between body size and generation time? Is there a correlation between body size and the size of your footprint? (Comparative Mammalian… Read more

Does How You Hold Your Guitar Affect the Sound?

Science Fair Project Idea

Scientific Method

What do a guitar, a piano, a harp and a violin have in common? Turns out a couple of things, including a soundboard. All stringed instruments use a soundboard to amplify (greatly increase) the volume of the sound coming from vibrations of the strings. The soundboard is positioned so that it gathers the sound vibrations coming from the strings and then retransmits them at an even greater volume when it begins to vibrate. Soundboards are common in the world of musical instruments, but they can… Read more

If you’ve ever had to wash dishes, you know that the right dish soap can make a dirty job a lot easier. Have you ever wondered how dish soap is able to clean dishes so much more effectively than water alone? Like many household cleaners, dish soap is a surfactant – it helps break up leftover food on plates by making it easier for food particles to dissolve in water. The dish soap also breaks up the water molecules themselves, which leads to some pretty interesting kitchen science… Read more

Does Virtual Practice Make Perfect?

Science Fair Project Idea

Scientific Method

You've probably heard the phrase, "practice makes perfect" more times than you care to remember, but is it actually true when you use a music game as your practice for real-life singing, strumming, or drumming? You can design a science fair project to discover the answer! First, you'll need to think about how to measure how well someone is playing or singing a song in real life. Using the test you design, measure several musicians' ability to play or sing a few different songs. Then have your… Read more

Does Wet Hair Float or Cling?

STEM Activity

Have you ever noticed how hair moves freely when it is under the water, but clings together as soon as it emerges out of the water? Not only human hair does this; when wet dogs shake themselves after a swim, their hair clings together in strands. Try this activity to see why wet hair is far less fluffy than dry hair! Read more
