Lighter than Air

When your environmental or earth science class is studying air pollution, you will want to take the time to go over this resource. Pupils peruse the history of air pollution regulations and examine outstanding diagrams of what...

Students construct and launch a hot air balloon. They are introduced to: Gas Laws, Air Pressure, Atmospheric Composition and Structure, Wind Speed and Direction, Inversions, and Weather Predictions. Students work in small groups to...

Students demonstrate that heat can change air. They determine that hot air rises. Students construct a working model of a hot air balloon. They understand that there are two ways that a balloon can rise: it can (1) be filled with a...

A variety of concepts are covered in this PowerPoint which gives the main engineering points of different aircraft types. Each slide details the engineering behind non-rigid and rigid categories of lighter or non-lighter than air...

Young scholars explore the concept of air density. For this air density lesson, students fill balloons with helium and carbon dioxide. Young scholars determine which gases are heavier or lighter than air.

Students study how hot air balloons were created and the different types there are.  In this density and lift lesson plan students build their own hot air balloon.

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).

"What would you attempt to do if you knew you could not fail?" This question guides Regina Dugan's exploration of amazing achievements in science and engineering that push the boundary of impossibility. From robotic hummingbirds and...

Students investigate what allows air plane to fly, why birds can fly and why people can't. They construct a giant hot air balloon that can be launched using only a hair dryer.

Students study various aspects of air. In this science lesson plan, students discover that air occupies space, understand the visual effects of air, and explain how air exerts force.
