This article reports on the wonders of winter weather, as it often inspires teachers' and students' interest in collecting weather data, especially if snow falls. Beginning weather data collection in preschool will introduce children to the concepts of making regular observations of natural phenomena, recording the observations (data), and looking for patterns in data. Through this, children become familiar with making observations in a scientific investigation as an ongoing process and become more aware of the weather. Children use symbols and vocabulary words in recording daily weather data to represent weather events such as a cloudy day. Exposing children to print supports their awareness of the importance of text, in comparing the recorded weather one month to the next, and in counting and creating simple graphs of their data. If the classroom is not located in an area with daily or seasonal weather fluctuations, another option is to make observations at different times of the day (e.g., early-morning temperature versus late-afternoon temperature). Children will enjoy having responsibility for the daily data recording. They will be practicing real science, collecting real data, comparing it, and discussing the meaning of the differences and similarities in weekly weather.
