Air -- Is It Really There?

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

Sure to be a hit with your charges, here is a science lesson that has lots of hands-on activities packed into it. The focus is simple machines, and how they help us perform work. After a discussion and demonstration session, groups of...

The lever is an everyday simple machine. Youngsters learn the principles of levers and explore their many uses. Groups of pupils perform a simple lab where they lift objects with a fulcrum while placing the load in a variety of...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

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...

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.

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.

What started out as a simple experiment about vacuums, turned into one of the most useful tools for predicting weather. Learn about the circumstances surrounding the invention of the barometer and the scientific principals...

Students investigate what simple machines are and how they work. In this simple machine lesson, the students create simple and compound machines and test each machine's ability to perform a task. Students compare simple machines to...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...
