Review information on the cycling of matter throughout the spheres of Earth.

[Free Registration/Login may be required to access all resource tools.] Describes the three states of matter of water.

Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.

A suite of lessons focusing on the basic elements of climate and weather. Inquiry-based exploration of extreme weather events and the factors of weather including clouds, wind, air pressure, temperature, and the water cycle.

A collection of grid puzzles that cover a wide variety of topics in intermediate high school chemistry. These are excellent for topic review and reinforcement. The puzzles can be played online and also downloaded as worksheets. Answers...

Learn about the conservation of mass and energy as it applies to different living systems.

Given scenarios, illustrations, or descriptions, the student will describe the flow of matter through carbon and nitrogen cycles and describe the consequences of disrupting these cycles.

A detailed overview of global climate change, with explanations of Earth's climate change, the carbon cycle, ecosystems, and greenhouse gases, and how the movements of matter and energy impact on climate. All information is reinforced...

Learners analyze food chains, webs, and pyramids to determine how energy flows and matter cycles through ecosystems.

Where does food come from and where does it go next? This unit helps students figure out that they can trace all food back to plants, including processed and synthetic food. They obtain and communicate information to explain how matter...

In this activity, learners will extend their knowledge of matter and energy cycles in an organism to engineering life cycle assessment of a product. Students will learn about product life cycle assessment and the flow of energy through...

Fourth graders will explore states of matter and the water cycle by bringing water to life with their bodies. By enacting the changes that water molecules experience, 4th graders will learn scientific information kinesthetically.

Investigate the changing states of water as you help Steve stay alive while in the Arctic. Includes background information about changing states of matter and about the water cycle, as well as a quiz.

Ecosystems contain two kinds of commodities: matter (nutrients) and energy. Nutrients cycle through the ecosystem, available for repeated use by organisms. These cycles of use and reuse are called biogeochemical cycles. Energy instead is...

Mercury in the geochemical cycle ultimately affects the food chain. Learn about this and its effect on the Everglades.

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

A collection of teaching resources that look at the carbon cycle and its role in a changing climate.

Review some of the cycles that recycle matter through Earth's biospheres.

[Free Registration/Login Required] An informational text about paper money as it cycles through the economy. A question sheet is available to help students build skills in reading comprehension.

Life on Earth is possible because energy flows one way through ecosystems, while matter cycles endlessly. Water and elements, such as carbon, nitrogen, phosphorous, and sulfur are examples of matter that cycles through ecosystems.
