Earth science experts learn about the roles of nitrogen by taking a virtual journey through the nitrogen cycle. Completing a passport worksheet along the way, they move from place to place around the classroom by the toss of dice. Each stop represents a nitrogen reservoir. Where this activity demonstrates how nitrogen molecules move, it does not provide much explanation of how. Make sure to teach a lesson based on the provided background information to make the lesson complete.
Learners identify the main concepts and ideas of the nitrogen cycle. They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical cycles.
A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry skills and nitrate sampling kits to detect the concentration of nitrate in stream water. This is comprehensively written, making it an ideal time saver when it comes to planning lab activities.
The nitrogen cycle is the focus of a well-designed science lesson. In it, learners see that plants and animals produce waste products and decompose after death. Many of the waste products include nitrogen which is absobed by other organisms. After a teacher-led demonstration, pupils are given nitrogen cycle cutouts and they create a nitrogen cycle based on what they've learned in class.
Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.
Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs create a nitrogen cycle.
Students investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the lesson. Students define the nutrient that is often limiting to plant growth through conducting research.
Students study the nitrogen cycle and construct a diagram.  In this Earth Science lesson students use role play to see the various paths. 
An inventive and interesting lesson on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved in the nitrogen cycle and the carbon cycle. They construct an abstract water cycle and place life forms onto an existing carbon or nitrogen cycle.
Fifth graders identify organisms and processes involved in three cycles: the water cycle, the carbon cycle, and the nitrogen cycle. They produce a pictorial or abstract water cycle, and appropriately place life forms onto an existing carbon or nitrogen cycle.
Tenth graders investigate two related scenarios that examine human impact on the nitrogen cycle. In the first example, 10th graders examine farm fertilizer runoff and its effect on a lake. Both of these examples strengthen students knowledge of ecosystems.
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.
Young scholars demonstrate and understanding of the nitrogen cycle by taking roles and interacting with others in a simulation activity.
Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place under-gravel filter in bottom of tank and cover with 5-10 lbs. of gravel.
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 lithosphere. Then, they will turn their attention to the carbon cycle as it is influenced by human choices and how human choice interacts within each of the four spheres. The instructional activity culminates as the class creates informational posters describing the cycle, ways humans negatively impact the carbon cycle, and ways they can improve it. 
Students are given guidelines to college level nitrogen budgeting. Students brainstorm the campus links to nitrogen budget. Students pick topics or subtopics for individual or group research. Students develop research plan, keep good records, report progress and report findings. Students submit final presentation both orally and written.
Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what carbon is and how it moves through each of Earth's spheres. They show how carbon moves by drawing a card and acting out the movement of the carbon as described on the card. This is a great visual way to represent the carbon cycle!
Young scholars create an ecosystem in a jar to show a model of the water, carbon, and nitrogen cycle. Working in small groups, they research and present orally the information they find on this cycle.
Students explain the role of different organisms in the food web. In this ecology lesson, students participate in a game to simulate mineral cycling through the web. They discuss the importance of recycling minerals and resources.
Students explore the cycles of an ecosystem.  In this environmental science lesson, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Students prepare a PowerPoint or other visual aide to be presented to the class.
