Students discuss what satyagraha is understanding that it is the driving force which enables social reform. For this social science lesson, students try to internalize the principles of nonviolence on an individual level and then a...

Learners compare and contrast the two types of whales. In this biology lesson, students research the characteristics of their assigned whale. They compile their findings in a folder.

Eighth graders distinguish between physical and chemical change. In this chemistry lesson plan, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took...

An air mass forms when the air over a large region of Earth sits in one place for many days. The air gradually takes on the characteristics of the land or water below it. Where Earth's surface is cold, the air becomes cold. Where Earth's...

What are air masses and where do they originate? What happens to the weather along fronts? Learn about warm and cold fronts and different types of advection. Maps and animated illustrations make these topics easier to comprehend.

A video and a short multiple-choice quiz on the topic of air masses and fronts. It describes the types of weather fronts, what an air mass is, and the four types of air masses in the US.

Get a quick overview of air masses and their movement.

This Oklahoma Climatological Survey explores how air masses form, as well as the weather formations, which tend to appear on the edges of these masses in what is known as a front.

Describes the different types of fronts and the dry line associated with certain fronts. Well illustrated with diagrams and maps.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-ESS2-5: interacting air masses and weather.

Students are introduced to air masses, with an emphasis on the differences between and characteristics of high - versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to...

A very detailed description of air masses, how they move and interact, and what weather takes place when this happens.

Investigation shows that gas takes up space and has mass, and that the motion of gas molecules is affected by heating and cooling.

Why do hot air balloons float? This resource from the NOVA Web site offers a series of interactive activities that illustrates the physics of hot air balloons.

By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.

It's difficult at times for younger young scholars to realize that air has mass. Matter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can't see it, and air has weight,...

The University of Oklahoma explores numerous types of weather and atmospheric changes, as well as the reasons behind them. Content details the four seasons, common meteorological variables, the vertical structure of the atmosphere, how...

[Free Registration/Login may be required to access all resource tools.] Describes the weather fronts that occur when two air masses collide. Includes downloadable handouts.

Explains three forces of nature and how they impact the weather. These include infrared rays from the sun, differences in air pressure, and wind flow when hot and cold air masses meet. Supported by lots of visuals.

Find the current air quality in Massachusettes, and learn more about air pollution, air quality forecast, and governmental guidelines on air.

This tutorial investigates how weather is influenced by the jet stream and air masses.

This Wikipedia site tells all about weather fronts, or boundaries between two air masses with differing characteristics. Includes many hyperlinked terms to additional information on related subjects.
