In this activity, students will collect weather data over several days or weeks, graph temperature data, and compare the temperature data collected with averaged climate data where they live.Key ConceptsWeather is the current atmospheric conditions, including temperature, rainfall, wind, and humidity, while climate is the general weather condi-tions. Comparing daily temperature with averaged climate data, students will understand that weather is highly variable, but climate is not. Scientists need a lot of data to average and understand regional climates or the usual conditions. To detect a change in climate, scientists need large amounts of data. They look for evidence of climate that existed long before humans made weather measurements. These climate records, including ice cores, lake bottom sediments, and tree rings, are called proxies. They are discussed in several of the activities that follow in this unit of the Cli-mate Discovery Teacher Guide.â€˘â€˘â€˘â€˘â€˘Â© 2005 UCAR, Version 1
Advanced PreparationFamiliarize yourself with the procedure for using your thermometers to collect atmospheric temperature data.Determine how long you want students to collect weather data (a week, month, or even all year). Depending on your regional climate, one week of data collection can be sufficient to illustrate weather variation (and may be more appropriate for younger students).
