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 this introductory lesson, students read an article about Arctic Ocean ecosystems and then play a board game in which they take on the role of researchers.
Objectives
The purpose of this introductory activity is to:
* Identify the main components of complex arctic ecosystem and describe predator/prey relationships between phytoplankton, ice algae, zooplankton, bowhead whales, polar
Students will use the TAMMNET project and accompanying PolarTREC resources to learn about seismology in the Antarctic, culminating in the creation of an annotated map using google maps.
Objective:
Students will understand the different ways mountain ranges are formed, and appreciate the questions unanswered about the Transantarctic Mountains. Students will also appreciate the ingenuity required for doing research in
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
Mount St. Mary's College in Los Angeles profiles one of its alumni, teacher Cristina Solis who also happens to be a PolarTREC alumnus. Read about her journey to become an educator and her participation in a PolarTREC study of microbial activity in thawing arctic permafrost near Barrow, Alaska.
Students will investigate what a carbon footprint is and calculate their own personal carbon footprint. Finally, students will develop ways to reduce their carbon footprint.
Objectives
Students will know that the principles of chemistry underlie the functioning of biological systems.
Students will know that carbon, because of its ability to combine in many ways with
Powerpoint presentation given at 2012 North Carolina Science Teachers Association professional development conference "Catch the Wave". Co-presenters Nick LaFave and Susan Steiner presented their PolarTREC experiences and information about PolarTREC.
Presented Powerpoint slideshow including two interactive activities for two 90 minutes sessions of North Carolina New Schools Common Practices Symposium. The presentation included activities I've used in the classroom based on the PolarTREC experience, as well as images from the summer at Toolik.
