Abstract	Clarifying ancient environments millions of years ago is necessary to better understand how ecosystems change over time, providing insight as to the potential impacts of current global warming. This module engages middle school students in the scientific process, asking them to use tooth measurement to test the null hypothesis that horse and tapir diets have not changed over time. Based on their tooth study, students are then asked to make a new hypothesis regarding the diets of these animals, testing their second hypothesis with dental microwear data. Students utilize multiple learning styles during their paleontology research projects, ultimately making scientific illustrations based on their analysis of the quantitative data.
