Science Fair Project Idea
Scientific Method
You can investigate how the geography of an area makes it prone to severe flash floods. Some areas, typically gullies or canyons, can flood extremely rapidly making it impossible to escape a flash flood. Compare the topography, or geographical shape, or these areas. What makes them prone to flash floods? Can you do an experiment showing how the flow of water increases as a channel narrows? Can you use topological maps of your region to identify areas at risk for flash floods? (NCAR, 2006;… Read more

Scientific Method
Did you know that commercial airline pilots use high-tech flight simulators to learn how to fly big jumbo jets? Before they ever step behind the controls of a real jet they've already logged thousands of virtual air miles. It might not qualify you to fly a real jumbo jet, but you, too, can learn the logistics of aviation by experimenting with the types of flight simulators sold at computer game retailers. Use a flight simulator to investigate the relationship between flap settings and the stall… Read more

Scientific Method
Floods can be very destructive, capable of leveling whole towns and decimating crops and fields. Typically in regions prone to flooding there are cycles of flooding that occur, usually in areas where a wet season comes after a period of drought. You can use precipitation data to test if incidents of flooding have been preceded by periods of drought. Look for long periods of dryness in the precipitation data to indicate a drought. You can also conduct an experiment on dry or moist soil to see… Read more

Scientific Method
Here's an interesting flash photography project. With an inexpensive Fresnel lens, you can concentrate the light from your flash. You'll be able to shoot with a smaller aperture and a shorter flash duration. This will give you greater depth of focus and will allow you to 'freeze' motion at higher speeds. The trade-off is that the light will be concentrated toward the center of the frame. This project shows you how you can investigate that trade-off and find out how you can best use your flash… Read more

Scientific Method
This project is a fun way to try your hand at programming. You'll learn how to create some simple animations, and you'll perform tests and make measurements to help you create more realistic-looking animations. All you need to get started is a Web browser and a text editor (like Notepad). Read more

Scientific Method
When watching a football game, have you ever wondered why some kicks lead to a successful field goal and others do not? There are a lot of variables at play in a game of football, and many of them are related to physics. One variable that can affect whether a field goal is successful is distance. In this science project, you will explore how field goal success rate is affected by distance from the goalposts. What will be the best distance for you to kick some field goals? Grab a football, head… Read more

Scientific Method
When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more

Scientific Method
When biologists want to separate different pieces of DNA, RNA, or proteins they use a technique called gel electrophoresis. In this science project you'll build a gel electrophoresis chamber and use it to discover how many components are in different colors of food coloring dye. Read more

Scientific Method
Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating the size of blood stains to the distance they fell, but do not get too grossed out. You will be doing it with fake blood. If you like figuring out mysteries, this is the science project for you! Read more

Scientific Method
When something goes wrong, do you like to try to figure out why? Engineers do this all the time. They even have a fancy name for it: failure analysis. Understanding how different materials break is an important part of failure analysis. Here's a project with one approach to studying the way things break. Read more
