Air Pressure is Powerful

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set students on lines that are...

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...

In class, your emerging environmentalists construct dust catchers. They take them home for a week or two, and then bring them back into class to examine under a magnifier. From this activity, they learn what makes up dust and that...

Blow some bubbles and learn how living things need air in the eighth lesson of this series. Young scientists investigate this important gas by observing bubbles and monitoring their own breathing. A simple and fun activity that raises...

This presentation is about air. What makes it unique is that, in addition to simply providing information about the components of air and the action of air pressure, it  includes a series of four experiments that bring these concepts to...

Make a hovercraft out of a compact disc, a balloon, and a few other materials. This is an activity that every physical science learner in your class can make if they bring a sports drink pop-top bottle to class. It will help them...

Four types of air masses interact in the atmosphere above the US. The collision of these air masses forms a front, which, in turn, creates our weather. Concepts are explained by Sam and RJ, thus preventing a snowball fight. Your class...

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...

Humans aren't the only species to build structures with air conditioning—we weren't even the first! The video explains how a variety of species that live under and above ground design their structures to allow for air circulation. It...

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...
