Description

In this computer lab, students investigate changes in the dates of frog first appearance and mating calls in the Ithaca, NY region between the early and late twentieth century.  These dates are compared to a variety of monthly and seasonal average temperatures recorded at area weather stations to determine any relationship between climate changes and species reproductive cycles.  Students then use future temperatures predicted by global climate models to infer further changes in frog behavior.  All of the data are already compiled in an MS Excel spreadsheet.
