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…
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…
Wind can make a cold day colder, or a hot day more pleasant. Use weather data to test the effect of wind on the temperature. How much of a change on the perceived temperature can the wind make? How is wind shear calculated? How can a wind barrier, like a wind breaker, keep you warm even if there is no insulating material? Build an instrument to measure wind speed or direction. (FI, 2006; GLOBE, 2006; NCAR, 2006; NOAA, 2006; Unisys, 2006; Weather Underground, 2006; WMO, 2006)
Many continents contain large mountain ranges that divide the continent into different regions. In the U.S. the Rocky Mountains mark the continental divide. The presence of a large mountain range can have a big effect on seasonal weather patterns. Also, the weather and climate on one side of a mountain range may be very different from weather and climate on the other side of the range. In the case of the Rocky Mountains, the western slope and eastern slope each have very different climates…
What are cold fronts and warm fronts? What happens when a cold front meets a warm front? You can test this using different temperatures of water. Use food coloring to label the cold and hot water, then carefully combine the two liquids together. What happens? How do they mix? You can also fill water balloons with hot or cold water, and then float in a hot or cold water bath. How does temperature affect the movements of the balloon? You can do similar experiments with hot and cold air in…
Fill a jar a little more than half full with fresh water. Make a solution of salt water, and add a drop or two of food coloring to it. Pour the salt water solution into a plastic cup with a small hole in the bottom, and then place the cup in the jar with fresh water. (The only connection between the fresh and salt water should be via the hole in the bottom of the cup.) With the right combination of hole size and salt concentration, you will see an oscillating current develop in the jar. …
There is a lot of energy that can be harvested from moving water. Energy can be extracted from water rushing over a waterfall and from the regular patterns of the ocean's tides. The energy that propels waves forward in the oceans can also be extracted and used. But can wave energy power plants be built anywhere there is water? In this energy science fair project, you will use ocean buoy data and mathematics to determine which locations along the coasts of the United States can sustain a wave…

You must have a computer with access to the Internet and spreadsheet software, such as Excel. This science fair project requires that you are familiar with spreadsheet software. If you need help learning more about the software, try using the tutorials that are part of the package, or an online tutorial.
Many people are surprised to learn that the season's we experience—winter, spring, summer and fall—have nothing to do with the distance of Earth from the Sun. In this science fair project, you will investigate how the temperature on Earth actually depends on the tilt of Earth's axis of rotation.

You will need a couple of specialty items: a globe of Earth and a heat lamp. Light from the sun can be used if a heat lamp is not available.
Average ($50 - $100)
Minor injury is possible, so be careful when using the heat lamp.
Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help…
