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...

Push the envelope with this instructional activity on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with...

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

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...

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...

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...

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...

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.
