This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
Article in Polar Record written by ARCUS staff and PolarTREC alumni educators that shares impacts of participating in a Teacher Research Experience.
Abstract: PolarTREC-Teachers and Researchers Exploring and Collaborating (PolarTREC) has provided the opportunity for over 160 K-12 teachers and informal science educators from the USA to work directly with scientists in the Arctic and the Antarctic. As a Teacher
Students will examine sunspots and track them at different latitudes on the Sun.
This activity is adapted from the Tracking Sunspots activity on NASA’s Solar and Heliocentric Observatory (SOHO) website (2009): https://soho.nascom.nasa.gov/classroom/for_students.html.
Objectives:
Students begin to familiarize themselves with solar activity by tracking sunspots at different latitudes on the Sun.
This activity is designed to get students thinking about
When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
This 1-hour webinar was part of the C-ISE online course being offered by PolarTREC and the University of Alaska Fairbanks. The presentation theme was earth science, and discussed climate change in the arctic and how scientists are using glacial features to study arctic change. The presentation was conducted by PolarTREC Teacher, Mark Goldner, researcher Ross Powell, and Research Experience for
PolarConnect event with Mark Goldner and the REU students and PI's that are in Norway. Three REU students presented on their experiments. A good introduction to the research questions and the area.
