Air Pressure

A penny can be a much more valuable teaching tool that you might think. Whether you are teaching about chemical reactions, surface tension, the behavior of gases, or are just looking for engaging activities for early finishers,...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a three year old boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll...

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...

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...

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.

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

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...

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...

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...

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...
