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

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.

In this unit, students learn the basics about weather and the atmosphere. They investigate materials engineering as it applies to weather and the choices available to us for clothing to counteract the effects of weather. Students have...

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.

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

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 out how good your weather prediction skills are as you study the movements of air and water, and their interactions. Then predict what the spring holds for residents of different regions of the United States, and what people should...

[Free Registration/Login Required] This flipchart is a beginning of a unit on weather. The flipchart contains information about fronts, air masses, and wind. There is an assessment quiz at the end.

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

The National Weather Service presents this site on synoptic meteorology, large-scale weather systems. Learn about the structure and behavior of the atmosphere, including clouds, precipitation, winds and more. Also includes learning...

Photos, diagrams, and other images related to weather.

No scientific phenomena concern us as much as the daily evolution of weather systems. We live in a culture where weather, the state of the atmosphere at a given time and place,helps us define regional cultural variations. States such as...

In simple terms, density is the mass of anything - including air - divided by the volume it occupies. In the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air's density depends...

Students learn that buoyancy is responsible for making boats, hot air balloons and weather balloons float. They calculate whether or not a boat or balloon will float, and calculate the volume needed to make a balloon or boat of a certain...

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 Required] A flipchart showing the separate stages of a frontal depression with reference to the weather charts that plot them, diagrams of the air masses that are moved around in them, and also of the cloud...

A collection of interactive concept models and active learning materials for teaching meteorology that illustrate conceptually difficult processes in atmospheric science. Active learning exercises are provided as guided instruction to...

Jet streams are like rivers of wind high above in the atmosphere. These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns.

A great description of the global scale circulation and heat energy. Discusses a single-cell model, a three-cell model, jet streams and more.

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