Ninth Grade, Weather & Atmosphere Science Projects (15 results)
Everybody talks about the weather, but nobody does anything about it.
- Charles Dudley Warner
Weather and atmospheric science offer lots of opportunities for interesting explorations. It's a satisfyingly complex area, with lots of online resources so you can make your project as easy or as advanced as you want. And when you're done, you'll have a science fair project everyone can talk about.

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…

Before you head for school for the day, you might check the weather to see whether or not you need to wear a jacket or bring an umbrella. It is pretty easy for you to check the TV or internet to see what the weather will be like today, tomorrow, or even next week. The modern-day science of meteorology, or studying and predicting the weather, has many advanced tools at its disposal that make it easy for you to get this information.
How did people predict the weather before the invention of…

Earth's atmosphere, the ocean of air that blankets the planet, is mostly nitrogen and oxygen, with small amounts of other gases. How much oxygen is present in air at sea level? In air high up in the Appalachians or Rockies? Atop Mount Everest? How much oxygen is present in the air you breathe? Here's a project that shows you how to measure the percentage of oxygen in an air sample.

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…

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…

Have you heard the term windchill used before? Maybe on the TV weather forecast? The windchill factor describes what happens to an object (like your body) when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body temperature (which, in extreme cases, can lead to death). In this science fair project, you will use a device to measure wind speed (an…

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;…

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!

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…

If you live in a humid environment, then you know that summer is not only hot, it is downright muggy. You can test the effect of humidity on temperature by measuring the temperature and humidity in your bathroom while running the shower. You can also use historical weather data to compare average seasonal temperatures in humid (e.g., Florida) and dry (e.g., Arizona) regions. How does humidity relate to temperature? Pressure? Why do humid environments tend to be coastal or tropical? How does…
