Science Fair Project Idea
Scientific Method
Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair.  Read more

Scientific Method
Is there a public park, playground, or beach near you that suffers from a litter problem? Here is a way that you can do something about it! First, get a measure of the size of the problem by conducting a litter survey. Select a fraction of the area to survey at regular intervals (e.g., every two or three days, or maybe once a week). The area should be large enough so that you can get a representative sample of litter, but not so large that you can't clean it up. Each time you conduct your… Read more

Scientific Method
The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole 3-4 million times the Sun's mass, is hidden by dust clouds in space. In this astronomy science fair project, you will use astronomical data to locate the center of this galaxy. Read more

How are we going to feed the more than 9 billion people that will live on Earth by 2050? This is a major question for farmers, ranchers, and food scientists around the globe. It's a big problem, considering that from 2017 to 2050 we will be adding 1.5 billion people and need 20% more food. Linked to this problem of producing enough food is having enough land, water, and other natural resources to make that happen. The final solution will surely be made up of many different approaches working… Read more

Scientific Method
The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more

Scientific Method
If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more
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
Science Fair Project Idea
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
The poet Carl Sandburg wrote, "The fog comes on little cat feet..." In this weather science fair project, you'll discover why this beautiful, quiet creeper appears on some days, and not on others. If you are fascinated by fog and weather conditions, this science fair project is for you! Read more
