This simulation from the National Center for Atmospheric Research portrays annual patterns in water vapor and precipitation across the globe, illustrating general circulation patterns as well as seasonal and regional variation.

Students discuss the characteristics of storms, including the relationship of weather fronts and storms. Using everyday materials, they develop models of basic lightning detection systems (similar to a Benjamin Franklin design) and analyze their models to determine their effectiveness as community storm warning systems.

Students are introduced to the basics of the Earth's weather. Concepts include fundamental causes of common weather phenomena such as temperature changes, wind, clouds, rain and snow. The different factors that affect the weather and the instruments that measure weather data are also addressed.

Students begin this lesson by considering how weather forecasting plays an important part in their daily lives. They learn about the history of weather forecasting -- from old weather proverbs to modern forecasting equipment and how improvements in weather technology have saved lives by providing advance warning of natural disasters.

Students are introduced to some essential meteorology concepts so they more fully understand the impact of meteorological activity on air pollution control and prevention. First, they develop an understanding of the magnitude and importance of air pressure. Next, they build a simple aneroid barometer to understand how air pressure information is related to weather prediction. Then, students explore the concept of relative humidity and its connection to weather prediction. Finally, students learn about air convection currents and temperature inversions. In an associated literacy activity, students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and are introduced to the role played by metaphor in language development. Note: Some of these activities can be conducted simultaneously with the air quality activity (What Color Is Your Air Today?) of Air Pollution unit, Lesson 1.

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 the opportunity to design and analyze combinations of materials for use in specific weather conditions. In the next lesson, students also are introduced to air masses and weather forecasting instrumentation and how engineers work to improve these instruments for atmospheric measurements on Earth and in space. Then, students learn the distinguishing features of the four main types of weather fronts that accompany high and low pressure air masses and how those fronts are depicted on a weather map. During this specific lesson, students learn different ways that engineers help with storm prediction, analysis and protection. In the final lesson, students consider how weather forecasting plays an important part in their daily lives by learning about the history of weather forecasting and how improvements in weather technology have saved lives by providing advance warning of natural disasters.

Students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. They explore what engineers can do to help reduce poor air quality.

This computer-based learning module engages students in questions that scientists around the world are exploring about Earth’s climate. They gain an appreciation for how much is not known about the Earth and climate change. The module contains 5 activities; 1) Earth’s Changing Climates, 2) Interactions Within the Atmosphere, 3) Sources, Sinks, and Feedbacks, 4) Feedbacks of Ice and Clouds, and 5) Using Models to Make Predictions. Each activity provides information in simulations, text, video, or graphic format and the students enter answers to both open-ended and closed questions within the program. Once the students have completed an activity, they can print a report showing all the questions and their answers. The authors estimate the entire module should take 225 minutes.

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 understanding of the composition of air. Next, students watch and conduct several simple experiments to 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). Finally, students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. In an associated literacy activity, students explore the environmental history timeline.

Students develop an understanding of the effects of invisible air pollutants with a rubber band and hanger air test and a bean plant experiment. They also learn about methods of reducing invisible air pollutants.

How does our climate affect us? How do we decide what to wear each day? What factors determine if our clothing choices are comfortable? What is the source of our water? Students explore characteristics that define climatic regions. They learn how tropical, desert, coastal and alpine climates result in different lifestyle, clothing, water source and food options for the people who live there. They learn that a location's latitude, altitude, land features, weather conditions, and distance from large bodies of water, determines its climate. Students discuss how engineers help us adapt to all climates by designing clothing, shelters, weather technologies and clean water systems.

In this activity, students will learn about how tornadoes are formed and what they look like. By creating a water vortex in a soda bottle, they will get a first-hand look at tornadoes.

Students develop an understanding of visible air pollutants with an incomplete combustion demonstration, a "smog in a jar" demonstration, building simple particulate matter collectors, and exploration of engineering roles related to air pollution. In an associated literacy activity, students learn basic marketing concepts and techniques, and the principles of comparative analysis, while creating an advertisement for a hybrid vehicle. Note: You may want to set up the activities for Air Pollution unit, Lessons 2 and 3, simultaneously as they require extended data collection time and can share test sites.
