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.
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.
The students' task is to produce a brochure for both the Arctic and the Antarctic. These brochures will be used by the representatives of "Here We Go Travel" to advertise the virtues of traveling to both polar regions. The students will produce a 45 second radio spot that they will write and record as part of their overall
Students will undertake a long term project to evaluate the effectiveness of different local forecasters, match the forecast with the actual weather and analyze which forecaster is best.
Objective
Students will compare the accuracy of different weather forecasts. Students will compile and analyze their own data gaining a better understanding of the challenges involved in weather forecasting
Finish newspaper, Maaseudun Tulevaisuus, published this article about Micheal Wing and the archaeology team working in Yli-Li. Attached is the translated article (by Reija Shnoro).
This activity is designed to make a connection between a group of scientists and the students.
Objective
Students will learn that scientists are people too.
Preparation
The teacher will need to contact a group of scientists to make sure they would like to participate in the project and to explain to them the goals of the
In this activity, students diagram the hydrologic cycle. Most of the concepts will already be familiar to middle and high school students, but this activity is a good way to prepare for making the far more challenging carbon cycle and energy NON-cycle diagrams.
Objective
* Students understand that the total amount of water on Earth is constant
In this activity, students diagram the flow of energy through the Earth's ecosystems. A lot of the concepts presented here are necessary in order to fully understand the greenhouse effect and global warming. This lesson is presented as an activity to do before embarking on a study of the greenhouse effect and global warming. Unlike water or carbon
