Do String Players Have Longer Left Fingers?

Science Fair Project Idea

Scientific Method

Physical activity is needed for maintaining normal bone strength and mass. Can physical stress on finger bones during development lead to an increase in finger length? Check out this project to see how violin players are an example of a "natural experiment" that you can use to answer this question. Read more

Have you ever wondered if people of all ages love sour foods, or if age correlates with this preference? There are a lot of different kinds of sour candies and drinks you may have seen advertised before, some having only a mild sour flavor and others that are truly mouth-puckering! In this activity you will investigate if there is a difference between the sour preferences of kids and adults. If you developed a super-sour food, to whom would you try to sell it? Read more

Does Birth Order Affect Grade Point Average?

Science Fair Project Idea

Scientific Method

Is there a correlation between birth order and grade point average? Design a survey study to find out. How many completed surveys do you need for a representative sample of your school? If you limit your survey to one school, would you expect it to be representative of a larger population (such as your county or state?) How do you control for potential effects of parental age at birth? (In other words, younger siblings will have a higher probability of being born to older parents. If there… 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

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

Don’t Forget! A Memorization Exploration

STEM Activity

What did you have for breakfast last Monday? What color is the floor in your favorite classroom? If you don’t remember the answer to these questions, that’s ok! Your brain is doing exactly what it is supposed to do. Our brains are nearly perfect storage devices, and part of their perfection is that they know which information to store, and which to throw away. Imagine your house if you never threw anything away – how quickly would it become full of garbage and waste? Your… Read more

If someone tells you to remember a phone number or address, it can feel like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds, you may find yourself starting to doubt your own memory. Was it 5-7 or 7-5? Our minds are always seeking new and useful information, and as a result, it will try to ‘throw away’ information that seems old or irrelevant, such as a random string of numbers or an address. However, there are… Read more

Don't Get Burned! Measure the UV Index at Different Times of the Day

Science Fair Project Idea

Scientific Method

It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.
