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

This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
