About This Lesson

This unit focuses on weather and climate. Students describe patterns of weather across time and location. They learn the difference between weather and climate.

Students study Earth’s atmosphere and the mixture of gases surrounding our planet. A major focus of this unit is the role of water in the atmosphere and the importance of evaporation, condensation, and precipitation.

Scientists collect data on atmospheric conditions—and students explore this process as they learn about weather instrumentation. Meteorologists use the information they gain from data collection to forecast the weather. Climatologists study patterns over longer time periods using much of the same data.

Students also learn that some forms of weather can be severe and hazardous, such as a hurricane, a tornado, or a lightning storm. People use engineering design to develop solutions that prepare society for hazardous weather and to minimize risks.
