This content has been created with the intent for the teacher to develop it to best suit their classroom setting. In its most basic form, students are asked to analyze wet and dry berry data to determine how water content changes (or doesn’t) for several berry species over the course of one season.
This lesson has multiple stages or
The night before I left Alaska I stayed up chatting with some of the scientists in the Toolik dining hall talking about my return to “normal civilization”. We spoke about the little habits that you pick up while at the field station and aren’t sure you’re going to let go (wearing sunglasses 24/7) as well as
This is the archive of the PolarConnect event with teacher Liza Backman and the team from the Phenology and Vegetation in the Warming Arctic 2021 expedition who presented live from Toolik Field Station in Alaska on 15 June 2021.
News article on teacher Liza Backman and her experiences preparing for a trip to the Arctic to work on the phenology of arctic plants in a warming climate.
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
