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...

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 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.

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's weather,...

Can your class predict the weather? Show them how they can come close with a lesson about creating weather instruments, including weather vanes, barometers, wind socks, anemometers, and thermometers. Kids research weather patterns and...

Take your class out to visit your automobile and use the tires to compute the weight of the vehicle. This is done by measuring the surface of the tire meeting the ground and the air pressure. This is a fun lesson in the relationship...

A succinct set of slides covers the main points for your weather unit. From the factors that contribute to conditions, to fronts and extreme occurrences, to the different types of clouds, numerous facts are listed in bullets. The only...

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...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

Put some pressure on your class to construct bottle barometers. Using a jar, a balloon, and a straw, they can make an instrument for measuring atmospheric pressure. Consider having your class do this at home. You may need to provide the...

A quick demonstration of the misbehavior of air pressure can be done with just a piece of paper. Have individuals fold one, place it crease-pointing-up near the edge of their desks, and blow beneath it. The opposite of what you would...

Using two 2-liter bottles, create the classic tornado tube. Once constructed, water swirling as it moves from one bottle to the other, forms a vortex due to the difference in pressure. You could either make one of these to keep in the...

Hank Green teaches how differences in air pressure, attempting to reach equilibrium. are what causes wind to blow. He also mentions Earth's rotation and the Coriolis effect. Have your class watch this video as a review to your lesson on...

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...

There's a lot going on here: air pressure changes, inertia, and chemical reactions. All of this occurs in 60 seconds time! As an end of the year physical science assessment, consider showing this video clip and then having learners write...

Push a straw through a potato using air pressure. This is a good for modeling how air pressure works.

Here is an unforgettable demonstration of the power of air! Because the column of air is about 250 miles or 400 km tall, its weight on a sheet of newspaper is enough to hold a stick in place as you smack the other end to break it....

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 little boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll of...

Several concepts are explored with Steve Spangler on the Ellen DeGeneres show. Combustion, air pressure, and polymers demonstrations are done, but very little scientific explanation is offered. At the end of the year, your could have...

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

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...
