Most students, regardless of their grade level, live “in the moment,” concerned only with factors and issues that have an immediate and direct impact on their lives. This is, to a large degree, understandable given the pressures, demands, responsibilities and constraints placed on students during their high school academic years. However, as teachers, we are required to not only
To begin the process of educating my students on my upcoming expedition to Antarctica, I introduced an activity entitled, “Questions about Antarctica…It’s What’s for Dinner.” In this assignment, small groups were asked to develop a list of 10 questions about anything - weather, clothing, wildlife, geography, geology, oceanography - related to Antarctica. Each question was worth up to 10 points
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 part two of this two-part lesson students work in pairs to explore the effects of temperature 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

This lesson investigates the impact of melting and freezing arctic sea ice on the properties of salinity, temperature and density that contribute to the stratification of ocean waters. This lesson combines several learning approaches including a hands-on lab, a web-quest and collaboration with other students.
Objectives
1. Students will be able to explain and demonstrate how Arctic
