Classroom Exercises Utilizing Precipitation Data.
Precipitation data for Macomb (Illinois) for the period 1912-1981 were the bases for developing classroom exercises that offered college students experience in collecting such data. After students collected the data, they reduced them to manageable proportions, and then examined average long-term relations which may have emerged among yearly, monthly, and daily values. This approach makes the study of weather and climate more relevant to students by utilizing local sources of data that students may find appealing and informative. Examples of the many figures, questions, and discussion topics that can be used in exercises to help students reflect on how the climate and weather conditions influenced the precipitation patterns are presented. For example, to get a concise summary of the general precipitation pattern in their community, the students placed on a graph yearly precipitation values for the entire period of record. To examine possible precipitation trends, students calculated a 5-year running mean for the Macomb data. The resulting graph helped to smooth the yearly fluctuations evident in their initial graph of yearly precipitation values, making the interpretation of dry and wet periods easier. (RM)
