Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
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
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
PolarTREC teacher Chantelle Rose wrote a guest column for the The Urbana Daily Citizen. This is the final installment in a series of guest columns planned to cover the local teacher's trip to the Arctic.
This data plotting lesson compares different stratospheric ozone data collected at the South Pole in September 1969, September 1998, September 2008, January 1999, and January 2008. This ozone comparison activity allows students to make conclusions about the annual and seasonal ozone hole as well as overall ozone concentration changes over Antarctica. Students use authentic data collected at the
This data plotting lesson is about temperature changes throughout the atmosphere. The data was collected together with the ozone data in January 2008.
The temperature vs. altitude profile allows students to make conclusions about annual and seasonal temperature changes in the atmosphere up to about 35 kilometers in the stratosphere. The best part of this lesson is using
