Air Density and Temperature

There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Students discuss radiant energy from the sun, performing a simple experiment with sun glasses and bright light to demonstrate the concept. Students further participate in simple in-class experiments to demonstrate: air density as it...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...

Only a minute and a half long, this video discusses how air acts as an insulator and why air higher in the atmosphere is colder than it is down closer to Earth's surface. He defines the lapse rate and shows how to calculate it. Because...

It is more than just blowing hot air. Pupils first build a hot air balloon out of tissue paper by cutting enough panels of tissue paper to form a balloon shape and glue the panels together. Using a hot air gun, individuals then inflate...

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...

Learners conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students conduct a series of hands-on activities to demonstrate that heated air expands and that warm air rises because it is less dense.

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.
