Air and Water Pressure

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...

Mr. Vanden Heuvel is in the bathroom again! This time he examines the strength of atmospheric pressure with a classic demonstration of filling a glass with water in the sink to reveal the column that fills the glass. Then he places a...

Guide your learners through the water cycle with this lesson plan. Over the course of the lesson, they read two Magic School Bus books, discuss the water cycle, come up with water facts, complete a diagram of the water cycle, recognize...

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...

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,...

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 stay...

How can you lift a heavy metal table using air? In this video segment adapted from ZOOM, cast members succeed in lifting a table using their own breath and a few plastic bags. [1:38]

Try this experiment with your class. Condensation in relation to temperature and water vapor in the air is shown through a simple experiment using cold glasses. Show this clip to your class or repeat this experiment and hold a scientific...

Through this experiment, students are challenged to lift a book (and other items) with just air. Requires simple household items, gallon-size, zipper-lock plastic bag, book, pencil, drinking straw, and tape.

Students conduct an experiment to discover what happens to air when it is heated or cooled, discover that wind moves from a high-pressure area (an area of sinking air) to a low pressure area (an area of rising air).
