Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
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
In this article, PolarTREC teacher Elizabeth Eubanks recounts her experience bringing her students - three eighth-graders and two seventh-graders to a week-long research conference in Alaska. "Having my students present at an international professional science conference is above and beyond any experience that I can offer them as a science teacher".
Elizabeth Eubanks M.Ed (working with Angela Gilmour, Anne Jensen, Danielle Dickson, Leslie Pierce, and Rachel Potter) connected with PolarTREC and NOAA TAS. This lesson is inspired by the need to share the importance of the Bowhead Whale in relation to the culture of arctic people. It is a portion of an entire collaborative unit to be utilized between
Elizabeth Eubanks PolarTREC teacher 2008 – Arctic Tundra Dynamics created this lesson to introduce her students to a wide variety of polar scientists and their research. Students will use the PolarTREC and other websites to learn about the various research projects that are going on at the poles. After students have tracked 10 polar scientists they are then
