The Dry Valleys Ecosystem project (a Long Term Ecological Research program - LTER) has been a continuous line of research since the inception of the McMurdo Dry Valley LTER since 1992. This project seeks to test hypotheses regarding the response of Antarctic biotic communities to changes in climatic conditions over time. I participated in the 30th
Teacher Bill Henske describes the science and fieldwork behind the Dry Valleys Ecosystem Study from McMurdo Field Station in Antarctica. This presentation took place on 24 January 2023.
Through this demonstration and review of the attached research documents and the expedition PolarConnect event archive you will better be able to visualize how warming deep ocean currents undermine the ice sheets of Antarctica.
Objectives
To determine, through a demonstration and review of a scientific abstract, how warm water currents speed up ice sheet loss and sub-ice
Models are great to use to make a concept easier to understand, to visualize a process or outcome, and also to allow a scientist to test selected variables. IMOLD is a great model of leaf decomposition, because it allows the students to interact with two variables affecting decomposition rates, and test those variables in many more ways than they could
This lesson describes how decomposition happens, and the role of microorganisms in this process. The animation, which runs for 3:23 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the animations, students can engage in a dialogue with the
The purpose of this lesson is to highlight the importance of the structure of a leaf at its implications for how it decomposes. The animation, which runs for 2:03 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the
The purpose of this lesson is to highlight the importance of the Carbon Cycle in the natural cycles of photosynthesis and respiration. It also models how human activity can alter the carbon cycle. The animation, which runs for 2:56 minutes total time, covers a large amount of information that students may or may not be familiar with. Here is one
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
As a teacher on the NB Palmer Totten Cruise in the winter of 2014, I successfully traversed the Magnetic South Pole. This is a wandering point on the Earth’s surface where geomagnetic field lines are directed vertically upwards. As an Outdoor Educator I utilize compasses regularly to navigate. The traverse of the Magnetic South Pole inspired this lesson
