Nitrogen Rides a 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...

High schoolers explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and...

Students study the basics of soil science. They research and gather data through readings, videos, and performance of laboratory investigations. As a team they generate oral and written recommendations for the amendment of soil.

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...

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....

Expose your class to the steps of the nitrogen cycle with this short clip. Colorful computer imagery and animation explain how nitrogen travels from the atmosphere as a gas into plants and soil, where bacteria convert it into nitrates....

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...
