Although this cleanses the air, it may create land and surface water pollution. Precipitation (rain, snow, etc.) washes pollutants from the air and onto the ground. When this occurs, weather fronts form, which often leads to some form of precipitation. Since several weather systems (high- and low-pressure systems) occur at the same time over North America, air masses are constantly colliding. (Refer to the associated activity Air Pressure Experiments: I Can't Take the Pressure! for students to expand their understanding of air-pressure). Low-pressure systems are pockets of air masses located between high-pressure systems. High-pressure systems are air masses with unique properties, such as warm or cool, or moist or dry. Weather systems typically are defined as being either high- or low-pressure systems.
Stagnant air can result in increased concentrations of harmful pollutants. Wind can move air pollutants from one location to another. Can they give specific examples? Daily weather conditions definitely affect the quality of the air. What kind of information is provided in a weather report? How does this information affect their daily lives?Īsk students if they think the weather has any effect on air pollution. Weather and Air Quality Reading (pdf) Visit [ to print or download.Īsk students to share whether they have ever read, watched or heard a weather report. International Technology and Engineering Educators Association - Technology The complex patterns of the changes and the movement of water in the atmosphere, determined by winds, landforms, and ocean temperatures and currents, are major determinants of local weather patterns.Īlignment agreement: Thanks for your feedback! Because these patterns are so complex, weather can only be predicted probabilistically.Ĭause and effect relationships may be used to predict phenomena in natural or designed systems. This lesson focuses on the following Three Dimensional Learning aspects of NGSS:Ĭollect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions.Īlignment agreement: Thanks for your feedback! Explain how engineers use meteorological information.Ĭollect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.Ĭlick to view other curriculum aligned to this Performance Expectation.
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. Finally, students learn about air convection currents and temperature inversions. Then, students explore the concept of relative humidity and its connection to weather prediction. Next, they build a simple aneroid barometer to understand how air pressure information is related to weather prediction. First, they develop an understanding of the magnitude and importance of air pressure. Students are introduced to some essential meteorology concepts so they more fully understand the impact of meteorological activity on air pollution control and prevention.
