It wasn’t until I heard Dr. King’s voice booming at me from the in-store entertainment system at the grocery store (“I have a dream that one day this nation will rise up and live out the true meaning of its creed.”) that I realized how close we are to Martin Luther King, Jr. Day.

In his honor, I present these resources:

Air pressure is the weight (or force) of the atmosphere at any particular point. Although you can’t feel it or see it, air pressure plays an important part in weather, and can be demonstrated with some really fun experiments.

KidsGeo.com: Atmospheric Pressure Makes the Wind Blow

“What type of pressure is there around you right now? Is your area surrounded by a high or low pressure? Unlike temperature, moisture, and wind, you can’t easily determine the pressure through your five senses. Because it is difficult to perceive pressure through our senses, it is tempting to assume that pressure is not very important. This assumption would be very incorrect. Pressure is extremely important, and has a dramatic effect on our weather.” This illustrated geology lesson for elementary and middle-school students includes songs (“Why Does the Wind Blow”) and an introduction to atmospheric pressure, density, wind patterns, and the Coriolis effect.

NASA: It’s a Breeze: Atmospheric Pressure

In addition to the short lesson, this NASA Kids Earth site includes three air pressure experiments, a word search puzzle, five discussion questions (“What do you think causes wind?”) and a couple of online experiments. One of these, called Take a Balloon Ride, demonstrates what happens to a hot air balloon as it rises from sea level to 10,000 meters. Can you guess what happens to the balloon when it is six miles above the earth? “As you move the mouse over the altitude scale to the left, you’ll notice that the balloon changes shape and size.”

NOAA: National Weather Service: Air Pressure

Today’s lesson from the National Weather Service Online Weather School is all about air pressure, and this online classroom is my pick of the day because of the six do-it-yourself experiments or labs, called Learning Lessons. Heavy Air is the first, and it demonstrates that air has weight by balancing a yardstick with two balloons to each end. If one balloon was heavier than the other, what would happen to the yardstick? Would the heavier end move up or down?
