Weather and Climate in Your Neighborhood

Science Fair Project Idea

Scientific Method

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more

Air Pollution

Science Fair Project Idea

Scientific Method

Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. … Read more

Hurricanes

Science Fair Project Idea

Scientific Method

Unless you live in the Southern states, you only hear about the most destructive hurricanes. In fact hurricanes occur every year, even multiple times a year. Each hurricane is a tropical storm related to cyclones and tornadoes, some big and some small. Each hurricane is measured based upon several variables like: wind speed, diameter, direction of movement and speed of movement. Does the size of the hurricane correlate with the wind speed? What information can the eye of the hurricane… Read more

Make Your Own Psychrometer

Science Fair Project Idea

Scientific Method

From the name, you might guess that a psychrometer is an instrument designed to measure your thoughts. Psych! Actually, it is an instrument that can help you forecast the weather. Read more to find out how it works. Read more

Ozone Depletion

Science Fair Project Idea

Scientific Method

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… Read more

Flash Floods

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

Floods

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

Foggy Forecasting: What Weather Factors Create Radiation Fog?

Science Fair Project Idea

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

How Do the Seasons Change in Each Hemisphere?

Science Fair Project Idea

Scientific Method

On a rainy day, do you ever wonder what the weather is like on the other side of the planet? Different regions around the globe can have very different seasonal weather patterns. In this experiment, you can test if these seasonal variations are related to which hemisphere each region is located in. Read more

Have you ever wondered how wind is made? Wind is caused by a difference in air pressure. Air travels from areas of higher pressure to places where there is less pressure. And just as air flows out of the high-pressure inside an inflated balloon if the opening is not tied, air in the atmosphere will move to a lower pressure area, creating wind. The speed of that wind can be measured using a tool called an anemometer. An anemometer looks like a weather vane, but instead of measuring which… Read more
