Gases Lighter and Heavier than Air

Scholars participate in two design challenges concerning flight in the second lesson of the series. They design balloon crafts that have neutral buoyancy and forward motion.

Plenty of background information about how air pollution affects much more than just our lungs is included on this attractive handout. After reading, pupils make a working model of a lung and diaphragm. Junior physicians place a small...

In this gases worksheet, students learn about the different gases and where they can be found. They fill out one section about gases and then complete 4 activities or experiments in which they learn more about the properties of gases and...

In one of the more memorable Spangler episodes, Spangler has a large terrarium filled with sulfur-hexafluoride gas, which is six times heavier than the air we breathe! It has some amazing properties, one of which it doesn't allow...

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).

Learners compare the relative densities of different liquids, first by layering them on top of each other, and then by weighing equal amounts of the liquids. They explore the density of air versus the density of water.

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 investigate the mysteries of air. In this science lesson, students participate in hands-on activities that require them to use the scientific inquiry model to study air.

Pupils observe several rocks and try to tell by looking and feeling, which rock is the heaviest, and which is the lightest. They take turns putting two rocks at a time in the balance scale to see which rock is the heaviest, then they...
