Science Fair Project Idea

Scientific Method

A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference. Read more

Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ

Science Fair Project Idea

Scientific Method

The human kidney is the most commonly transplanted organ in the United States, numbering more than 17,000 transplants in 2010 alone! But kidney transplantation technology faces a lot of challenges, including a shortage of kidney donors and the need for recipients to take immunosuppressant drugs to keep their bodies from rejecting a transplanted kidney. In this science project, with the help of bioinformatics databases, you will explore how a kidney could be bioengineered using stem cells,… Read more

Building Banjos

Science Fair Project Idea

Scientific Method

The banjo's roots trace all the way over to Africa. The unique sound that a banjo makes depends, in part, on the resonator. The purpose of the resonator is to amplify and project the sound that is made by strumming and plucking the strings. In this music science fair project, you will experiment with a resonator on a banjo and see if you can hear the difference in sound. Read more

Making Species Maps

Science Fair Project Idea

Scientific Method

How do conservation biologists know which places are important to protect? How do nature guides know which animals can be found in which places? In this experiment you can discover how maps can be used to show how different animals are distributed in a local environment. 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

Rubber Bands for Energy

Science Fair Project Idea

Scientific Method

If you have ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! But just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Read more

Yeast Reproduction in Sugar Substitutes

Science Fair Project Idea

Scientific Method

There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Clean Up The Water with a Trash-Skimming Robot

Science Fair Project Idea

Engineering Design Process

Engineers are trying to tackle the world's ocean pollution problem using robots. Some robots, like Mr. Trash Wheel and the ship featured in this Mark Rober video, are stationary and collect trash as it flows out of rivers before it gets into the ocean. Others, like the Jellyfishbot, are mobile and can squeeze into narrower spaces to collect trash: Can you build and test your own trash-skimming robot? If you do not have access to a natural body of water to test it in, you can use a bathtub or a… Read more

Do Hurricanes Cool the Ocean?

Science Fair Project Idea

Scientific Method

If you've ever so much as watched a news clip about a hurricane, you probably know that hurricanes draw their power from warm ocean waters. If that is true, does it mean that hurricanes actually cool the ocean down when they pass through? Can the amount of cooling be measured? Is it proportional to the strength of the hurricane? Find out using data that you can collect yourself using online archives. This project shows you how. Read more

Make Your Own Hot Air Balloon

Science Fair Project Idea

Scientific Method

Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.
