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 Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's… Read more
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.

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… Read more
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… Read more
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… Read more
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
As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more
