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.

Students will independently explore the PolarTREC expeditions, and reflect on the scientific questions, discoveries, and outcomes of the work that is or has been done.
Description
Students will visit the PolarTREC website at www.polartrec.com, where they will find a teacher who is in the field presently, or was already in the field. You may select one expedition
Craig Kasemodel is joining researcher Lee Cooper aboard the USCGC Healy in the Bering Sea. This live event highlights some of the research and activities taking place on board the ship. There were about 11 parties who joined the event, and there were about 60 students.
Students are presented with an actual series of tundra photos, which they use to develop a hypothesis for which sort of ground cover will have the most/least permafrost depth. Then they are given a set of actual data and use this to test their hypothesis
Objective
Students will:
* understand what permafrost is and how it develops
This lesson was modeled after some of the routine activities undertaken by the geologists on the Kuril Island Expedition.
Complete the following activities:
* Day 1 To measure a simple topographic profile with a level instrument or hand level and stadium rod.
* Day 2 To use the measurements from Day 1 (and/or actual measurements from the Kuril
