Learners explore aerodynamics and Bernoulli's principle by devising ways to keep bubbles aloft.

Don't let learning about airplanes be a drag. An instructional video explains how advances in technology led to planes that can fly higher, resulting in less drag, less fuel, and the need for a pressurized cabin. It also explains why...

Rather than show this video clip, perform the demonstration for your earth science class. Because of the difference in air pressure caused by your moving stream of air, a very long plastic bag can be filled with a single breath! This...

In 1852, a German physicist, Magnus, talked about an effect first described by Isaac Newton in 1672. Part of a series, an interesting video explains the Magnus effect and previous attempts to apply it to transportation. It also shows a...

Students, in groups, create experiments to predict and prove what a change in pressure can do to objects exposed to the change. They use AppleWorks to write their hypotheses and the steps they need to conduct the experiment.

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...

Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...

Do not let the pressure get to you. The first lesson in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure air pressure and...

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.

Two versions of this activity are presented for you to choose from when teaching about Bernoulli's principle in your physical science class. One is a hands-on activity, while the other would be best used as a demonstration during...
