In this activity, students will use data collected about two male arctic ground squirrels by researchers at Toolik Field Station in northern Alaska. Each squirrel had a lightlogger to record light intensity (lux) and an implanted data logger to record internal body temperature (°C). Students work individually or in pairs to analyze the data sets and interpret the results
This lesson focuses on adaptations as a driving force in evolutionary diversity. Adaptations are characteristics within a species that enhance its chances of survival and reproduction. Adaptations can be behavioral, structural, or functional. Students must understand that these adaptations are not acquired in the course of the organism’s lifetime, but are inherited traits that have been passed down
