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
Free community viewing of Taking Earth's Temperature -Delving Into Earth's Past followed by Q & A w/contributor Dr. Jason Briner. Organized by PolarTREC teacher, Tina Ciarametaro in her home community after her expedition to Greenland. Learn more here about the documentary Taking Earth's Temperature.
This one hour webinar is conducted by PolarTREC alumni Missy Holzer. She highlighted her work with the High Arctic Change expedition 2008 and bringing inquiry-based science into her classroom. This webinar is part of the C-ISE online professional development course.
In this one hour webinar, PolarTREC teacher Susan Steiner and researcher Michael Weintraub explain the science, research questions, and results of their work at Toolik Field Station.
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
This lesson allows students to use online mapping tools to investigate global snow cover changes. Students develop a problem statement about global snow cover and then use mapping tools to investigate their problem or question.
Objective
Students will become familiar with the data and tools used to analyze snow cover changes in order to answer questions pertaining
