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 introductory lesson, students read an article about Arctic Ocean ecosystems and then play a board game in which they take on the role of researchers.
Objectives
The purpose of this introductory activity is to:
* Identify the main components of complex arctic ecosystem and describe predator/prey relationships between phytoplankton, ice algae, zooplankton, bowhead whales, polar
In part one of this two-part lesson students work in pairs to explore the effects of salinity on ocean stratiļ¬cation using a simple plastic shoebox-sized container in which they create a mini-ocean environment. Students will apply what they learn in the lab setting along with information gained in several online articles to a basic understanding of the Global Conveyor
PolarTREC teacher Nell Herrmann writes a compelling article for Town and Gown, the local newspaper in her home town of State College, PA. Nell reports on her adventures with a team of scientists in Antarctica and the profound way in which her journey has influenced her both personally and professionally. Note: The online article starts on p. 50 of the
Listen in to this radio interview on National Public Radio's program, "All Things Considered" with PolarTREC teacher Nell Herrmann. Nell describes her excitement about traveling to Antarctica and her role in a study of Antarctic seafloor organisms and their response to changes in water acidification and temperature. Nell outlines her plans for sharing the research team's findings with her students
