The Carbon Cycle
When it comes to the carbon cycle, the sky really is the limit. The activity begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles.

Oxygen Cycle
Students run clockwise around a track in the gym, pretending they are the blood that carries oxygen through the body. They go to the "mouth" station where they take three breaths and pick up an object that represents oxygen. Students...

The Nitrogen and Phosphorous Cycles
How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...
Curated OER
Dissolved Oxygen and Temperature
Young scholars are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

The Cycle of Matter
An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form.
Virginia Department of Education
The Cycles of Nature
Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid depicting the chosen...
