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 Sense of Touch Impact a Cat's Behavior?

Science Fair Project Idea

Scientific Method

Have you ever seen a cat slowly move its head and whiskers into a small space before crawling through it? They’re using their sense of touch to see if they can fit into the space! In this science experiment, you’ll test how cats use their sense of touch to move through the world by using a maze to determine if they prefer big or small spaces. Read more

Does Temperature Affect the Rate of Butterfly Development?

Science Fair Project Idea

Scientific Method

This is an interesting experiment if you are 1) curious about insect metamorphosis and 2) patient! You will need to set up different controlled environments for the chrysalides, and then check on them regularly as you wait for them to hatch. 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 Weight Affect a Drone's Battery Life?

Science Fair Project Idea

Scientific Method

Drones—also called quadcopters or unmanned aerial vehicles (UAVs)—are an increasingly popular toy for hobbyists. Some companies even want to use them for business purposes, like delivering packages right to your doorstep! However, drones typically have a rather short battery life. Does the added weight of a package affect a drone's battery life? Try this project to find out! 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

Dog Scents: The Super Nose of Man's Best Friend

Science Fair Project Idea

Scientific Method

Everyone thinks their dog's the best, but in the case of smelling ability, all dogs possess super powers. In fact, a dog's nose can be over a 1,000 times more sensitive than a human's! In this project, learn about smell from a dog's unique perspective. There will be a whole lot of sniffing going on when you set up these fun experiments to find out what scents your dog and other canine friends find most interesting or appealing. Read more

Dog Toys: What Makes One a Favorite or a Flop to Fido?

Science Fair Project Idea

Scientific Method

Got a pampered pooch in your household? Then you know how much most dogs love their toys. And not just any toy. It has to be that particular beat up ball, gnawed frisbee, or ratty not-so-plush-anymore bunny with only one eye and partial ear remaining. Seems that dogs, like people, have definite preferences for their play things. This fun project investigates what makes a toy interesting to a dog. In these experiments, you and your dog can have some fun while you learn about canine behavior… Read more

Domino Theory

Science Fair Project Idea

Scientific Method

Have you ever set up a line of dominoes and watched them fall? If you wanted to make your line of dominoes fall faster, do you think you should set the dominoes up with more or less space between them? Set your dominoes up in a straight line, using a ruler to keep the spacing between them constant. Try different spacings at 0.5cm increments. Conduct multiple trials at each spacing, and time how long it takes for a fixed total length of dominoes to fall (e.g., a 1.5 or 3.0 meter length of… Read more

Drag Racing in the Water

Science Fair Project Idea

Scientific Method

It's fun to go swimming! To feel the power of your body as you launch yourself into the water. But did you know that swimming isn't just about skill and athleticism? The human body consists of skin, contours, and curves. How the water moves along your body and the clothing you are wearing determines how fast you can go. In this science fair project, you will investigate the effects of a force called drag. You will compare the time it takes to swim 25 meters in a swimsuit versus swimming the… Read more
