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
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.
As part of a migratory bird study conducted with my bilingual second graders in Washington, DC, the students in my elementary science class spent four weeks getting to know all about birds! We initially focused on birds that migrate from our Mid-Atlantic forests to the tropical forests of Central America (an area where many of them are from)
This lesson came out of a desire to connect the plankton research that I did during the 0902 Healy cruise with my young "researchers" back in Washington, DC. I wanted them to understand that plankton not only feed the Arctic but that much of the world relies on these little critters that come to life for us when we look
Students will become familiar with the anatomy/physiology, habitat and lifestyle of puffins. On the 2009 Healy Icebreaker expedition the wildlife survey team was primarily interested in bird diversity and population in the Bering Sea. Puffins were spotted during the cruise, especially feeding in and around Dutch Harbor, Alaska.
Objective
* Students will learn about the unique nature of puffin
