Overview
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.
Objectives
- Students will use data collected from arctic researchers about arctic ground squirrels.
- Students will learn how scientists use the data they collect to answer their research questions.
Lesson Preparation
- Students should have a good working knowledge of Microsoft Excel. Some background about hibernation and the Arctic is helpful, but is not necessary.
- Photocopy the handout for each student.
- Reserve a computer lab or have students bring in their laptops.
Procedure
Students should work through the data-processing individually or in pairs, and ask for help as needed. They should make the graphs and either print them out, or sketch them in their notebooks, depending on teacher preference.
Extension
Students can use the second data set to compare and contrast the results between two male arctic ground squirrels to look at individual differences.
Resources
An excel file with data from two arctic ground squirrels is included, along with the worksheet and an answer key.
Assessment
Answers can be self-assessed during class discussion, or can be collected and graded.
