Science Fair Project Idea

Scientific Method

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather? Read more

Make a Motion Sensor Alarm with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever wished you could create an alarm system to guard your stuff? Or what about throwing a surprise party for someone and automatically playing music and flashing lights when they walk in the door? You can do either of these things using a Raspberry Pi. The kit includes a motion sensor, which can detect when people move in front of it. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using… Read more

Make an Adaptive Switch

Science Fair Project Idea

Engineering Design Process

How could you send a text message without using your thumbs? What about typing on a keyboard or using a video game controller without using your fingers? Due to a variety of medical conditions like cerebral palsy or paralysis from an accident, some people might be unable to easily use their hands and fingers to push small buttons or use joysticks. However, they might be able to use their entire hand to push a single larger button or use another part of their body like their foot or even their… Read more

'Make Mine Medium-Rare': Heat Conduction in Steak

Science Fair Project Idea

Scientific Method

How do you like your steak? The internal temperatures for beefsteaks at various levels of "doneness" are as follows: medium-rare, 145°F; medium, 155°F; medium-well, 165°F; and well-done, 170°F. What factors determine how long you have to cook a steak to reach the desired temperature? The temperature of the steak before you start to cook it will clearly be important. The temperature the steak is cooked at will also be a factor. And of course, the thickness of the steak will… Read more

Make Your Own Electric Guitar Pickup

Science Fair Project Idea

Scientific Method

If you like playing electric guitar, this could be a cool project for you. Have you ever wondered how an electric guitar works? In this project you'll wind one or more of your own electric guitar pickups and test them out in an inexpensive electric guitar. How will the sound change with the number of turns you use in the coil? Or with the strength of the magnets you use? Read more

Maybe you have grown vegetables or flowers, but have you ever grown the flowerpot? Yes, you read that right! In this activity, you will use mushroom roots to grow a biodegradable material that can be molded into a product of your liking, like a flowerpot! Growing a set of bowls, a lampshade, or a pot is easier than you might think. Once you try it out, you just might feel inspired to replace some of your plastic objects with ecological counterparts that you created from mushroom roots! Read more

Making It Shipshape: Hull Design and Hydrodynamics

Science Fair Project Idea

Scientific Method

Sailboats, tugboats, barges, ocean liners, submarines are all different boats with different shapes. How does the shape of a boat's hull affect how easily it moves through the water? This project shows you how you can investigate this question using a homemade water trough and model boat hulls. Read more

Making Maple Syrup Candy: How Does Temperature Affect It?

Science Fair Project Idea

Scientific Method

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made. Read more

Making Patterns with Rubik's Cube

Science Fair Project Idea

Scientific Method

This project challenges you to figure out how to make geometric patterns with Rubik's Cube. Leaving your cube in one of these positions makes it much more tempting to pick it up and 'fix' it. Can you figure out how to make a checkerboard, or a cube-within-a-cube? Can you make only the center piece a different color from the rest? Can you figure out how to solve the cube from these positions? Read more

Mapping Troposphere Ozone Levels Over Time

Science Fair Project Idea

Scientific Method

Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, i.e., the air that we breathe, it is harmful to health. In this project you can use data from EPA monitoring stations to analyze the weather/climate conditions that can lead to harmful ozone levels. Read more
