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.

Students are introduced to the concepts of air pollution and air quality. The three lesson parts focus on the prerequisites for understanding air pollution. First, students use M&Ms to create a pie graph that expresses their...

Students use the Motion Detector to measure the effect of air resistance on falling objects. They determine how air resistance and mass affect the terminal velocity of a falling object and then choose a force model that fits the data.

A quick lab experiment to determine if air has mass and can be considered matter. This activity can be part of a unit of matter. Lesson plan includes instructions for a format for a mini lab report and student instruction sheet.

In this science lesson students will be asked the question, "Does air take up space?" and "Does air have weight?" Students will conduct experiments that prove that air has mass, takes up space, and exerts pressure.

With the study of weather we need to know that there is air mass like fronts that change weather. This site shows us the different kinds of fronts that we experience.

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

[Free Registration/Login Required] Learn about Newton's 2nd Law - the relationship between force, mass, and acceleration for a hot air balloon using this interactive simulation. A PDF worksheet and a video tutorial are also available....

This site discusses weather forecast computer modeling, or numerical weather prediction (NWP). It also discusses the development of the concept of front and air masses, as well as which computer forecast models are currently being used...

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...

Why does a lot of hail, rain, or snow fall at some times and not others? This unit contains four separate lesson plan sets built around answering this question. In the first two lesson plan sets, learners explain small-scale storms. In...

One-page profile of influential innovator, Juan Trippe, whose vision and ideas revolutionized air travel with the birth of mass aviation and Pan American Airways.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

[Free Registration/Login may be required to access all resource tools.] Acceleration due to gravity and why falling objects with different masses accelerate at the same rate.

Information on what weather is to begin with, then progresses to how scientists can predict the weather. Common ways to predict weather are also included such as use of a barometer and rain gauge.

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...

In this interactive activity from NOVA Online you can move an air mass over a mountain and see how several distinct microclimates are created.

Learn all about wind, what it is, words used to describe wind, the different types, the coriolis effect, different types of breezes, and how wind is measured.

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...

In the following tutorial, students will learn how to express mathematically the drag force and also discuss its applications. They will also define terminal velocity and determine the terminal velocity given mass.
