My PolarTREC expedition to the Dry Valleys of Antarctica was an experience of a lifetime. Notice I did not use the word “trip” of a lifetime. This was far more than a trip. It was an experience that is a life-changer. It has been a life-changer for myself, my students, my family, other educators, and other folks
Ice is a medium that nearly everyone is familiar with. We put it in drinks, skate on it for hockey and scrape it off our windshields in winter. Ice can be turned into sculptures and can even make for some fantastic winter scenery. Ice can also turn into a kaleidoscope of color and patterns under the right circumstances. Science
This lesson is intended to help students make connections to polar science while discovering how and why sea ice drives deep ocean currents. Students will also learn key terminology related to sea ice and using actual salinity content charts, will graph a typical sea ice core’s salinity as it relates to depth.
A little over 1 year ago, I received a phone call that changed my life. I had been selected to become a PolarTREC Teacher and would be heading to Antarctica in the fall of 2017. Words cannot adequately describe the joy and excitement I had in that moment. I knew I was headed for
My experience at McMurdo Station involved the study of neutrons caused by cosmic radiation from the sun. The sun can be very active. Changes in the sun's active surface can result in the ejection of high energy particles (from solar flares, coronal mass ejections, or related phenomena). Some of these particles can get sent toward the earth
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
The report is written by teacher participants upon return from their field expedition portion of the PolarTREC program. It summarizes the benefit of the expedition to the teacher, a description of activities, and a summary of how teachers plan to link this experience in classrooms and communities. This is a public document that will be posted in teacher portfolios and
Oceanography is the study of the ocean. It covers a wide range of topics from marine life to the geology of the sea floor to the physical properties of the ocean. Physical oceanographers study the physical components of the ocean including light, waves, tides, currents and the composition of sea water. The physical properties of the ocean can
