Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

If you teach a man to fish, he will never go hungry—or he will overfish and permanently damage the ecosystem? Address the traditional biomes as well as the human-included ecosystems and contrasts the biotic and abiotic factors in each....

Website from Global Learning and Observations to Benefit the Environment (GLOBE) Program with comprehensive learning and field study resources on the biosphere in which students use materials and data to make observations and learn about...

A learning guide about the biosphere. Includes information about the National Science Education Standards. Requires Adobe Reader [PDF].

[Free Registration/Login may be required to access all resource tools.] Earth's biosphere is introduced to demonstrate what the Gaia Theory does for the environment. Students will also understand what homeostasis is.

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 3 of 3 in the series titled "The Biosphere."

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 1 of 3 in the series titled "The Biosphere."

[Free Registration/Login may be required to access all resource tools.] Discover the hierarchal system found in the biosphere which helps scientists break down and delve into different aspects of ecology.

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of...

The carbon cycle is one of the most important cycles. It is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. This cycle is important because it...

Try considering the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere....

This tutorial will investigate the levels of organization from the atom to the biosphere.

In this lesson, you will learn about how the Earth formed as well as the composition and structural layers of the Earth's interior.

Energy is neither created nor destroyed - and yet the global demand for it continues to increase. But where does energy come from, and where does it go? This video examines the many ways in which energy cycles through our planet, from...

This site provides information and activities for classes to learn more about ozone depletion and UV radiation.

While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological...

Learning module introduces students to the human dimensions of global environmental change: human actions that initiate changes in the structure and operation of the biosphere; the consequences of these actions on terrestrial ecology;...

[Free Registration/Login may be required to access all resource tools.] This lesson explains the levels of organization within the biological world. It looks at the cell to organism hierarchy, and at the population to biosphere...

[Free Registration/Login may be required to access all resource tools.] Like water and carbon, nitrogen is also repeatedly recycled through the biosphere. This process is called the nitrogen cycle. Learn more about the nitrogen cycle in...

Bobbi Seleski catalogs biology from our body and beyond, tracking how unicellular organisms, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and our biosphere build off of each other and work together....

[Free Registration/Login may be required to access all resource tools.] Explains the cycle of carbon through the atmosphere, geosphere, and biosphere.

A detailed overview of the Earth's climate, with explanations about the difference between weather and climate, dendrochronology, palynology, and how Earth's climate has changed over time. All information is reinforced through pictures,...

A comprehensive ecology learning module where students assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems.

[Free Registration/Login may be required to access all resource tools.] Covers interactions between organisms.
