Biochemical Cycles: Recycling Carbon and Nitrogen

Not original, but nicely organized, this worksheet reviews the four biogeochemical cycles: carbon, nitrogen, phosphorous, and water. Youths are asked to draw a diagram and then answer questions about each cycle. This worksheet can be...

An interesting lesson takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third lesson in a series of 21 discusses...

The four cycles in Earth's biogeochemical system are covered in this activity. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

Humans can have a big impact on the environment, specifically the influence they have on the carbon cycle. First, the class will define and discuss each of the earths four major spheres, the biosphere, hydrosphere, atmosphere, and...

Explain the two-step process of photosynthesis to your high school biologists with a focus on the Calvin cycle. Using adorable animation, a video likens the cycle to a tiny, sustainable factory. Even though the enzyme-bird rubisco and...

A woman had a job crushing cans at the recycling plant; it was soda pressing. Video focuses on the ways our environment recycles, including the water cycle, carbon cycle, nitrogen cycle, and the phosphorus cycle. It also describes the...

A comprehensive lesson on product life cycle, energy consumption, and personal carbon footprint is described in this resource. Lead high school environmental science buffs through the complex process of product production and discussions...
