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
IMOLD is a highly interactive website designed by Drs. Michael N. Weintraub and Daryl L. Moorhead in collaboration with the Center for Creative Instruction at the University of Toledo. Susan Steiner, PolarTREC teacher with Dr. Weintraub on the expedition, Tundra Nutrient Seasonality, collaborated on IMOLD’s design. Other teachers have contributed wonderful classroom activities that can be found posted
In this set of lessons, students have the opportunity to think like scientists as they examine actual data related to Arctic ground squirrels, organize it in logical ways, and make inferences based on the data.
Objectives
Students will develop an understanding of some of the ways scientists use and organize data.
We want students to develop the habits, traits, and qualities of effective scientists. What better way for them to learn what these traits are than by hearing from actual scientists? In this lesson, students watch video interviews with four Arctic scientists from the University of Alaska, notice what types of work scientists do on a daily basis, and make
This lesson was written for the 2012 Arctic Ocean Ecosystem Workshop and was inspired by the research work conducted off the coast of Barrow, Alaska by researchers Steve Okonnen and Patricia Yager with PolarTREC teachers Lollie Garay and Chantelle Rose. Students will engage in a series of exercises to investigate seasonal change in the Arctic ecosystem based on authentic
Small groups of students will establish their own phenology plots for long term study. Students will make a field sketch of a sample plot and turn it into a scale map. The map will accurately place plants the students have identified for tracking phenophases, so that the plots can be monitored long term. Phenology is a vital part of
This versatile activity was inspired by my own Antarctic voyage (Lollie Garay, Oden Expedition 07) and The Amazing Race. As my students followed the journey through the Antarctic Seas on a USGS map, I realized what a great opportunity this was for them to "see" where I was in a part of the world so foreign to us
