Adjust the altitude and temperature in this simulation to observe how gas pressure is affected by these changes.

Students create their own barometer, calibrate it with the actual air pressure data, and compare that data with the boiling temperature of their water. They learn from this that atmospheric pressure affects the boiling points of liquid....

Students will experience a hands on reference for high and low pressure as it relates to air movement. This activity will help with understanding high and low pressure behavior.

Discusses the fronts and weather patterns associated with low pressure areas.

Describes the ways in which wind direction and barometric pressure can be used by the amateur weather forecaster to make predictions about the weather.

[Free Registration/Login Required] Observe what happens to the barometer as the weather changes from clear, to mixed, to overcast. Then answer a challenge question about the topic.

A series of virtual experiments that show students the power and importance of evaporation.

Explore some virtual experiments on gases and vapor pressure, the Maxwell speed distribution, the barometric formula, and heat and temperature.

A calculator that computes air density if altitude, temperature, humidity, and barometric pressure are known.

[Free Registration/Login Required] Hike to the top of Mt. Everest and observe what happens to the amount of molecules pushing down on the surface of the Earth. After the activity, answer one challenge question about the topic.

This site, which is provided for by the Franklin Institute Online, gives a format for keeping a weather journal.
