Soil Microbiology- Nitrogen cycle

When learning about several different processes at a time, it can be difficult to differentiate between them. In the resource found here, you can see what your kids know about some of Earth's systems including the carbon, hydrologic,...

Students study the nitrogen cycle by participating in a lab.  In this liquid nitrogen lesson students divide into groups and compare their edible items to the nitrogen cycle. 

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...

Young scholars investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the lesson plan. Students define the nutrient that is often limiting to plant growth...

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...

This short presentation provides a convenient introduction to the nitrogen group in the periodic table of elements. A graphic displays where they are placed in the periodic table. The nitrogen cycle is mentioned and ammonia is explained....

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...

You will get much mileage out of this resource. It is three presentations in one! Standard general ecology information is included within these 69 slides. The first segment deals with levels of organization, biotic and abiotic factors,...

Students design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.

Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...
