In this inquiry-based activity, Roborovsky hamsters are used to provide students with an opportunity to develop their skills of analysis, inquiry, and design. These hamsters are easy to maintain, yet offer students a means to use conventional techniques and those of their own design to make further observations through measuring, assessing, and data collection. Based on the premise that this is a directed rather than dictated student inquiry, the activity will vary based on discussions and recommendations suggested by each class. (Contains 12 figures and 3 online resources.)
