Pressure

Find out how we describe the force created by the blood against the walls of the vessels in a heart-pumping lesson! As part of a unit on the heart and circulatory system, cardiology kids use a blood pressure monitor to find their...

Figuring out the partial pressures of various gases in a container is the focus of this chemistry video. Sal sets up a problem where a balloon is filled with three different types of gases: oxygen, hydrogen, and nitrogen. The goal is to...

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...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Do you work better under pressure? Pupils explore pressure when altering fluid density, gravity, container shape, and volume. Units can be converted to kPa, atm, and psi. To finish, scholars describe pressure as a function of depth,...

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.

Begin by discussing pressure and showing a video clip of James Cameron's record-setting deep-sea dive. Then assign lab groups to explore how depth affects pressure and to construct a manometer. There is another video to follow the...

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.

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...
