Science Fair Project Idea

Engineering Design Process

How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! Read more

Develop Your Own Soda Pop Recipe

Science Fair Project Idea

Scientific Method

Carbonated bevarages are quite popular in the United States (despite the health risks of drinking too much of the sugary ones). Many people love their bubbly, fizzy flavors. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sweetener to create a your own soda pop. Once you develop your recipe, try it out on your friends and family. Who knows? You might create the next soda pop sensation! Read more

DIY Popsicle Stick Drone STEM

Blog Post

Series of STEM activities guides students in building and experimenting with a popsicle stick drone. From a beginner build to adding advanced Arduino controls, follow along to build and test your own mini drone! Drones can be fun (and challenging!) to fly. A drone's hovering flight may look effortless, but whether you've experimented with a drone indoors or outside, you know that a lot goes into expertly navigating a drone to keep it in the air and… Read more

Dome Sweet Dome

Science Fair Project Idea

Scientific Method

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like (or partially sphere-like) structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science project, you will get to build a geodesic dome using rolled-up newspapers and tape. How much mass do you think your dome will be able to support? Build one and find out! Read more

Drugs & Genetics: Why Do Some People Respond to Drugs Differently than Others?

Science Fair Project Idea

Scientific Method

In a survey conducted from 2007 to 2010, the U.S. Centers for Disease Control and Prevention reported that about 49% of people in the United States had taken at least one prescription drug during the past month, and about 22% of people had taken three or more prescription drugs. People are prescribed drugs all the time, but prescriptions can be dangerous because people can have different responses to drugs. These responses largely have to do with genetic mutations. Why are some genetic… Read more

From Genes to Genetic Diseases: What Kinds of Mutations Matter?

Science Fair Project Idea

Scientific Method

Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.

How Does the Intensity of Light Change with Distance?

Science Fair Project Idea

Scientific Method

How does the intensity of a light source change as you move away from it? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. It does not matter if you are talking about a lightbulb or the sun; this law still applies! Read more

How Greasy Are Your Potato Chips?

Science Fair Project Idea

Scientific Method

One of America's favorite snacks is potato chips. Although potato chips are very tasty, some varieties are not very healthy for you. A typical 1-ounce (oz.) serving of a well-known national potato chip brand contains 150 calories, 90 of which are from fat. How greasy are your favorite potato chips? Try this science fair project, and you'll get a visual understanding about how much oil a potato chip can hold. Read more

Have you seen a rainbow in the sky after a rain shower? How many colors were there? A rainbow is often described as having seven colors: red, orange, yellow, green, blue, indigo and violet, but you might spot a rainbow and see fewer colors. Or you might see more than seven! It can be tricky to count the colors in a rainbow, because they all blend together so seamlessly. Want to see for yourself? In this activity you will explore the physics of light and create your own mini-rainbows. How many… Read more

How Much Fat is in Your Food?

Science Fair Project Idea

Scientific Method

Have you ever been told to avoid certain foods because they contain too much fat? Almost every food we eat has some amount of fat in it; often in an invisible form so we do not even notice. However, eating healthy does not mean getting rid of all fat in your diet. On the contrary, fat is an essential nutrient for your body! Only consuming too much of certain fat types creates problems. Are you curious about how to determine the fat content of different foods? Gather some chips, chocolate, and… Read more
