Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
This Live from IPY! event was part of the International Polar Week in October 2009. The theme of the week was was 'What happens at the poles affects us all'. This live event was held with PolarTREC teacher Cristina Galvan and the University of Wyoming polar bear research team on 8 October 2009. They were working on the USCGC Polar

This short article is an U.S. Fish and Wildlife Service fact sheet about Ursus maritimus, the Polar Bear. It covers basic information, including: appearance, feeding habits, reproduction, adaptations, and protection.
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).
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
