Antarctic ecosystems are undergoing change at unprecedented levels. In this lesson, students will use real data to evaluate the effect of climate change on Antarctic fish. Denise Hardoy created this lesson plan after joining Dr. Anne Todgham’s team studying Antarctic Fish Development Under Future Ocean Conditions in October/November of 2019.
Denise Hardoy created this resource after spending five weeks embedded with Dr. Anne Todgham’s team studying the effects of climate change on Antarctic fishes in 2019. This lesson addresses one of the most difficult aspects of science for students - making sense of data.

Success Criteria
* Given a graph, students will write an analysis paragraph of a
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
Students will learn about adaptations that allow fish to survive the frigid waters of Antarctica and will make calculations to demonstrate how they survive these conditions.
Objective
* Students will determine how much antifreeze an Antarctic fish needs to lower the temperature of it's body fluids to -2.5°C. *
* Students will develop an experimental procedure to conduct their
