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
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
In this one hour presentation, PolarTREC teacher John Wood explains the scientific work in the Carbon Balance in Warming and Drying Tundra expedition from Healy, Alaska.
Even in Antarctica ice will melt. As the sun stays higher and higher in the sky as summer progresses, the warm sun causes the ice to melt. The questions that we are going to ask are: 1) Does clean ice (no sediment) or dirty ice (has sediment mixed in it) melt faster? and 2) Would the ice melt if
The local on-line newsletter interviewed Mr. Wood over the phone and talks about the upcoming expedition to the interior tundra of Alaska and how it will involve the students at Talbert Middle School in Fountain Valley.
We know that we have lots of microorganisms growing where we live, but can microorganisms like bacteria also live in the harsh, cold, dry climate of Antarctica? Part of our research project in Antarctica is looking at the microorganisms that live in the Taylor Glacier. We are taking dirty ice (ice with lots of dirt/sediment in it) and
For this experiment, we are going to melt dirty ice (ice with lots of sediment/dirt in it) and clean ice (ice without sediment) from the Taylor Glacier. After we melt the ice, we are going to test the melt water for pH and conductivity, and then determine how much salt is actually in our ice samples. There are
Students will engage in a hands-on activity to help them consider what students in a tropical climate do to prepare for recess compared with students who live in the interior of Alaska.
Objectives
Students will:
* Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska.
* Learn
Through activities, video observation, experimentation and the construction of a Remotely Operated Vehicle (ROV) students will learn about the chemical and physical properties of sea ice.
Objectives
Students will be able to answer main questions of where sea ice is, how it is formed, why the ice is important, how it is classified by indigenous people and scientists, how
The title of this lesson, 'Ssssno Seals' is a play on words. Will the ice seals survive? Yes or No? Paul Lukosi is a high school teacher in the lower Yukon River Delta, 6 miles from the Bering Sea...as the slough goes. The village he teaches in is heavily focused on family and culture, and has survived for thousands of
