Chlorophyll Conundrum: Can factors affect chlorophyll levels in plankton samples?

Overview

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

Reeling in CTD Data

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

Identifying Sea Ice

Students will undertake three different activities to help them identify a variety of Antarctic ice types.

Objective

To provide sensory experiences that will move students toward conceptual understanding of the types of sea ice found in Antarctica.

Preparation

It is suggested that teachers survey the Resources section before beginning this series of three classroom activities for background information
