Altitude and Elevation
*
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...

Dry Spells, Wet Spells: How Common Are They?
Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the contintental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged rain? The most consistent precipitation? Here's one way to find out.

Make a Hygrometer with Strands of Hair
Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a
hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather?

Latitude
*
Temperature also changes with latitude. As you move away from the equator, the temperature tends to decrease. Test this by comparing weather data from weather stations at different lattitudes....

Humidity
*
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...

Pressure
*
How does temperature change as barometric pressure changes? You can make a device to test this using a barometer and a thermometer on your stovetop. You can collect your own weather data from a...

How Does Atmospheric Temperature Affect the Water Content of Snow?
Are you a snow aficionado? What atmospheric conditions produce light, powdery snow, and what conditions produce heavy, wet snow? This project shows you how to use data from daily balloon soundings of the atmosphere and your own snow measurements to find out.

Using Weather Balloon Data to Map Atmospheric Temperature
Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily from weather balloons.
