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
The PolarTREC expedition places the teacher in the role of student. All aspects of the expedition ask the teacher to stretch her mind and reach beyond her comfort zone. This stretch presents itself to the teacher in having to learn new technology, new science, new presentation formats, and meet, live and collaborate with
Data collected from experimental manipulations of ecological processes can help us understand the natural world, and perhaps even help scientists predict how complex systems may change. At CiPEHR, (Carbon in Permafrost Heating Experimental Research) located near Denali National Park, scientists have collected and analyzed seven years of data to learn how increases in soil temperatures influence the carbon
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
