Science Fair Project Idea
Scientific Method
So baseball's your game? Well, slugger, science and math abound in baseball. Just look at the zillions of "stats." In this project, you can produce some interesting baseball statistics of your own and perhaps settle a long-standing debate. You'll set up experiments at your local playing field to find out which type of bat is better, wood or aluminum. Play ball, and batter up! Read more

Scientific Method
Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project. Read more

Scientific Method
What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

Scientific Method
Although fractal images can be intriguingly complex, fractals are more than just pretty pictures. In this project, you'll explore the mathematical properties of the famous Mandelbrot (illustration on the Background tab) and Julia sets. You'll learn about how these images are generated, and about the relationship between the Mandelbrot set and the Julia sets. Read more

Scientific Method
Social media is all the buzz on the internet. What can we do with all the information generated by millions of people posting, tweeting, taking pictures, and chatting? How do companies convert it into profit? While you do not have the tools to analyze data from millions of social media posts by yourself, you will be able to analyze a scaled-down version. Follow the instructions in this project to try your hand at extracting data from a couple of social media sites and use it to create… Read more

Scientific Method
Balloons are a festive addition to many celebrations. You've probably noticed, though, that over a short period of time, helium-filled latex balloons start to lose their buoyancy. So when you're planning your next party, how soon can you buy the balloons in advance before they start deflating? In this science fair project, you will use a simple scale to measure the lift supplied by a set of balloons, and determine the rate of lift decay. Read more

Scientific Method
Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Scientific Method
If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

Scientific Method
How do you figure out how to get places? Do you ask for directions, look at a map, or consult a compass? There are many ways for people to figure out how to travel from one place to another, but how do other animals do it? In this science fair project, you'll use real data, collected by biologists, to figure out how migratory birds manage to navigate more than 2,000 miles from their breeding grounds to their wintering grounds.

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
