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.
Teacher Betsy Wilkening and researchers publish an article in the Journal of Geophysical Research stemming from their work on the PolarTREC OASIS project.
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska. (See Ocean Atmosphere Sea Ice and Snow (OASIS) Project at www.polartrec.com)
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interactions) study these pollutants in the Arctic. Students will learn about actions that they can take to
Excerpt:
Almost every student at Wilson has probably heard of Mrs. Wilkening, a seventh grade teacher with a mad passion for science. She keeps her science classes alive with her eccentric and fun lessons. Mrs. Wilkening also has had two kids go through Wilson herself. Patrick, her son, was actually part of this school's first kindergarten class, and Jeannie, her
