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 stratification 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
1) Why is it important to collect large quantities of research data?
2) How can photographing a subject be similar to scientific observation?
3) How can one plot photographic data on a map?
Introduction:
This lesson was written for a Photography I course, to be taught in a lab with access to either a darkroom or computers/printers. The
Antarctic educator, Mark Walsh, created this video for the PolarTREC 2013 spring online professional development course. This video uses the concept of Density to explore how mountains are built as well as how to throw a good Cinco de Mayo party at McMurdo Station Antarctica. He uses the Dr. Samantha Hansen's Transantarctic Mountains work as an example of mountain building.
Students will use the TAMMNET project and accompanying PolarTREC resources to learn about seismology in the Antarctic, culminating in the creation of an annotated map using google maps.
Objective:
Students will understand the different ways mountain ranges are formed, and appreciate the questions unanswered about the Transantarctic Mountains. Students will also appreciate the ingenuity required for doing research in
Working at Terra Nova, Antarctica. This is the Italian Base where PolarTREC teacher Brian Dubay and his team continued their study of the Transantarctic Mountains.
