Air Pressure

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct research...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer, teams...

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's weather,...

What started out as a simple experiment about vacuums, turned into one of the most useful tools for predicting weather. Learn about the circumstances surrounding the invention of the barometer and the scientific principals that it...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Students discover that air pressure is pushing on us all the time although we do not usually notice it. This lesson discusses the units of pressure and gives the students a sense of just how much air pressure is pushing on them. Students...

Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.

Did you know that there are many air pressure experiment that you can do in your very own home? Dr. Carlson demonstrates a few, and then explains the cause of air pressure at an atomic level. Rather than show this video in class, have...
