Soil Microbiology- Nitrogen cycle

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...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

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...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Young environmentalists examine the biogeochemical cycles: carbon, nitrogen, phosphorous, and water. Explanatory notes and colorful diagrams are presented for each, followed by a blank diagram that is filled in click-by-click as a...

AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and...

A respectful resource is available to support your ecology lecture. Introduce the population concepts of limiting factors and carrying capacity and then examine the example of a deer population in northern Arizona. Take a look at the...

We wish you a happy, healthy, and phosphorus school year! A video explains the importance of getting the nutrients that are needed and focuses on the nitrogen and phosphorus cycles. It includes discussions on the importance of bacteria...

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...
