Wire Wilt: How Light-Emitting Diodes Fade As Temperature Increases

Science Fair Project Idea

Scientific Method

What's your favorite thing to do on the hottest day of the year? Dip your toes in an icy river? Hang out by the pool? Retreat to a cool basement? Lie motionless in the shade? You're probably not too eager to move around and put out a lot of energy, like mowing the lawn in the mid-afternoon sun. Well, you're not the only one. In this electronics science fair project, you'll find out that some semiconductor devices, like light-emitting diodes (or LEDs), act the same way. As their internal… Read more

See Air Currents with Shadowgraphs and Schlieren Images

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more

Using AI to Detect Proper Exercise Form

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how Artificial Intelligence (AI) can be used to improve human health and medicine? Computers can now identify human joints as key points to track our body movements. They can then use this information along with training data sets to show us if we perform exercises safely, to prevent us from getting injured. Create your own data set and test out if your algorithm can reliably detect good and bad exercise form. Read more

Sleep Tracking: The Brain and Circadian Rhythm's Role in Sleep

Science Fair Project Idea

Scientific Method

Everybody sleeps, but not everybody has good quality sleep. Sleep is essential for the brain, but how do our daily choices impact sleep? In this science project, you will experiment and explore factors that influence your nighttime sleep schedule. Read more

Mix It Up: Transferring Heat by Convection in a Tank

Science Fair Project Idea

Scientific Method

Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

How Direct Reprogramming Can Transform One Type of Cell Straight into Another

Science Fair Project Idea

Scientific Method

In the first decade of the 21st century, scientists found ways to make one adult cell type turn into a completely different cell type. This has huge implications for the medical field, including being able to take some cells that a person could spare, such as skin cells or blood cells, and turn them into another cell type that might be much more important for that person to have, such as cells to make a new kidney. How are scientists able to accomplish this amazing feat of "reprogramming" the… Read more

Standing Waves on a Guitar

Science Fair Project Idea

Scientific Method

In this project, you'll investigate the physics of standing waves on guitar strings. You'll learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you'll figure out how to produce the various modes by lightly touching the string at just the right place while you pick the string. This technique is called playing harmonics on the string. By the way, we chose a guitar for this project, but you can do the experiments using any stringed instrument, with… Read more

Piaget's Theory of Conservation: When One Cup of Water is Less Than One Cup of Water

Science Fair Project Idea

Scientific Method

Having a younger brother or sister can be a real chore. They can get into your things and mess up all your stuff. But have you ever thought that when younger siblings do this kind of thing, they are actually learning about the world around them and how to interact with their environment? Every day, a young child's brain is getting new information about his or her environment and developing ways to organize that information. Learning about and understanding this conduct is the study of human… Read more

Science Fair CSI: Can You Predict the Spatter?

Science Fair Project Idea

Scientific Method

There is evidence to be gathered at every crime scene. The hard part is making sense of it all. That's where crime scene investigators and forensic scientists come in. In this science fair project, you will investigate blood spatter using fake blood. Your job, as an impartial scientist, is to deliver facts so that justice can be served. Are you up to the challenge?

Smarter Farming with Aerial Photo Analysis

Science Fair Project Idea

Scientific Method

Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.
