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
At Summit Station, Greenland, science technicians measure the snow conditions of the runway to determine if the LC-130 aircraft which brings supplies and people in and out of Summit can land and takeoff safely.
Students can use data taken by technicians at Summit Station, Greenland and develop a model to determine if snowpack conditions on the runway are sufficient
In this set of lessons, students have the opportunity to think like scientists as they examine actual data related to Arctic ground squirrels, organize it in logical ways, and make inferences based on the data.
Objectives
Students will develop an understanding of some of the ways scientists use and organize data.
We want students to develop the habits, traits, and qualities of effective scientists. What better way for them to learn what these traits are than by hearing from actual scientists? In this lesson, students watch video interviews with four Arctic scientists from the University of Alaska, notice what types of work scientists do on a daily basis, and make
PolarTREC teacher Alicia Gillean shares her impressions of the Arctic tundra and details about her expedition to Toolik Lake, Alaska to study arctic ground squirrels.
Article in the Oklahoma Jenks District Gazette about PolarTREC participant Alicia Gillean's experiences and arctic impressions following her expedition to study ground squirrels at Toolik Lake, Alaska.
PolarTREC teacher Alicia Jenks is inspiring her students with her expedition to Toolik Field Station, Alaska. She will be studying Arctic Ground Squirrels.
Just as the increase in atmospheric CO2 is causing the global air temperture to rise, the container with the added CO2 will trap more heat inside and will show a higher internal temperature.
Overview
This activity/demonstration can be used directly following lessons on greenhouse gasses and their effects on warming the atmosphere by allowing shortwave UV energy
