Impacts of a field experience on teaching high school science
Early in my teaching career, I learned that authenticity is essential in creating working relationships with my high school students. By showing them that I am a human being with experiences, ideas, dreams, and opinions, I’m able to connect in ways that invite their attention as I teach skills
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
Newspaper article related to outreach at the Mystic Aquarium Women in Science Day. URI researchers and PolarTREC teacher Cara Pekarcik were interviewed about their upcoming research trip to Antarctica.
Quincy Access Television interview: PolarTREC teacher Cara Pekarcik talks with Joe Catalano on the Currently in Quincy Program. The conversation includes descriptions of the PolarTREC program, a description of the research project and day-to-day activities as well as a discussion about student and community outreach.
Article from the Patriot Ledger (Quincy, MA) introducing the Southern Ocean Diatoms PolarTREC expedition. The article focuses on a presentation for North Quincy High School students by Dr. Bethany Jenkins. Jenkins, as well as graduates students from the University of Rhode Island spoke to students about diatoms, life on the R/V Nathaniel B. Palmer and specific tools and techniques related
This one hour webinar is part of the International Polar Week celebrations sponsored by APECS, ARCUS and PEI. The presenters are young scientists that work in the Polar Regions. They shared information about their work as well as how they became interested in polar science.
This one hour long event features researchers Karita Negandhi, Brittany Potter, John Lenters, and Reny Tyson. Karita has a marine biology background but currently studying Arctic thaw ponds, while Brittany and John study lakes in Barrow, Alaska and Reny studies humpback whales in Antarctica. This webinar is hosted by ARCUS and the Association for Polar Early Career Scientists (APECS) for
Glaciers are slow-moving masses of ice that exist where more snow falls than melts. They occupy about 10% of the Earth’s land, mostly in Greenland and Antarctica. Here, glaciers can be as much as 2 miles thick and weigh more than millions of tons. As they move, glaciers can widen and deepen valleys, flatten forests and grind boulders
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
