UCAR Center for Science Education The Nitrogen Cycle Nitrogen is an element that is found in living things like plants and animals, dead things like fallen leaves and dear animals, and non-living things like air and water. The nitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems.
Energy Flow Through Ecosystems Summary:The objective of this lesson plan is to give students a basic understanding of how energy flows through an ecosystem by introducing them to the concepts of food chains and energy pyramids. Included in this lesson are two small group activities and a power point presentation. The power point presentation provides the students with fundamental knowledge about one way that organisms in an ecosystem interact and depend on one another. By using the power point lecture, the students are able to visualize food chains and energy pyramids. It is hoped that through the small group activities, the students will help each other gain a better understanding of how energy flows through an ecosystem.
Would You Eat That? The Game of Naming What's in What You Eat Getting the most out of what you eat takes knowing what's in your food. While packaged and prepared food can save time, it takes a lot of chemistry to keep those items edible on the long trip from the factory to your face.

Climate Discovery Teacher's Guide Welcome to the Climate Discovery Teacher's Guide! This teacher's guide was produced by the National Center for Atmospheric Research as a companion to the Climate Discovery exhibit at our Boulder, Colorado laboratory. Each unit contains lessons appropriate for grades 5-9 on a variety of Earth system science topics that facilitate student learning about our planet's climate system. The lessons in each unit can be viewed using Adobe Acrobat Reader and may be reproduced for educational use. Note: This project is in development.
Environmental Data Explorer - The Environmental Database (search United Nations Environment Programme environment for development Environmental Data Explorer Population Issues & Facts - Population Connection When Population Connection was founded as Zero Population Growth, or ZPG, in 1968, there were 3.5 billion people on the planet. Since then, our world population has doubled – with no end in sight. The United Nations projects that world population will reach 9.6 billion by 2050, and nearly 11 billion by 2100. Why does it matter? One in eight people is hungry.
