Explains what an occluded front is and how it forms when three air masses interact.

Students are introduced to the concepts of air pollution and air quality. The three lesson plan 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...

Experiment to see how air resistance affects the periodic motion of a mass on a spring.

[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...

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...

[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.

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...

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.

See how atmospheric pressure affects air masses, which in turn affects the weather on Earth.

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...
