Energy Flow Through Ecosystems
Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...
Curated OER
The Nitrogen Cycle
Students study the nitrogen cycle and construct a diagram. For this Earth Science lesson students use role play to see the various paths.
Curated OER
The Nutrient Cycles
Students investigate the circle of sea life by creating nitrogen compound models. In this oceanography lesson, students discuss sea creatures and where their waste goes. Students identify nitrogen cycles in the ocean by viewing...

Greenhouse Gas Emissions – Natural and Human Causes
Part three in the series of seven has pupils discussing the different greenhouses gases, learning about the carbon cycle, and then watching a short video about the carbon cycle. Based on their knowledge, individuals complete a greenhouse...
Chicago Botanic Garden
Greenhouse Gas Emissions — Natural and Human Causes
What impact do humans have on greenhouse gas emissions? What are the natural causes of these gasses? Thanks to the carbon cycle, carbon dioxide eats away at the earth's atmosphere with the intensified help of humans. Young scientists...
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

Biochemical Cycles: Recycling Carbon and Nitrogen
Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.
Curated OER
The Carbon Cycle
In this carbon cycle worksheet, students will read about the carbon cycle and study a diagram showing what creates carbon dioxide and what uses carbon dioxide. Students will then complete 4 short answer questions.
