In this activity, students will use IB-style data-based questions centered around graphs made from data collected about arctic ground squirrels by researchers at Toolik Field Station in northern Alaska. Activity levels of ground squirrels are analyzed in relation to solar radiation and ambient temperature. Students work individually or in pairs to answer the questions.
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
Students will collect soil samples and analyze them with some of the same procedures used by researchers in the McMurdo Dry Valleys, Antarctica. Soil microfauna (e.g. nematodes) will be extracted from the samples using a Baermann funnel. Students will compare their own data to published data from researchers working in Antarctica.
PolarTREC has been an amazing experience, wow! The heart of the PolarTREC program is the field expedition, which allows the teacher to be embedded in a field research team. STEM educators are passionate about what they teach but often lack access to meaningful opportunities to participate in basic research. Programs like PolarTREC provide that missing
Teacher Josh Heward discusses research with the "Tough Tardigrades Team" in the McMurdo Dry Valleys in Antarctica where they search for tardigrades and other microorganisms that live in the soil.
Alicia Gillean discusses her 2013 Arctic Ground Squirrel Studies expedition at Toolik Field Station, Alaska, and how it impacted her personally and professionally.
Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
In this set of lessons, students have the opportunity to think like scientists as they examine actual data related to Arctic ground squirrels, organize it in logical ways, and make inferences based on the data.
Objectives
Students will develop an understanding of some of the ways scientists use and organize data.
