Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
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
President Obama recently named 102 researchers as recipients of the Presidential Early Career Awards for Scientists and Engineers, the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their independent research careers. Researcher Samantha Hansen, who worked for two field seasons in Antarctic with PolarTREC teacher Brian DuBay will be one
This video clip from from Alabama TV 13 News profiles PolarTREC researcher Dr. Samantha Hansen's work studying the history of landforms in Antarctica. Dr. Hansen will be one of a hundred scientists to be awarded the Presidential Early Career Awards for Scientists and Engineers.
While in Toolik Lake, Alaska, PolarTREC teacher Susan Steiner worked with a robotic platform that traversed sections of tundra collecting information on a variety of different environmental variables. This article describes the sensors and instrumentation used on the platform in greater detail.
