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 activity based on the provided background information to make the activity complete.
The nitrogen cycle is the focus of a well-designed science instructional activity. 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.
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.
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.
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 lesson culminates as the class creates informational posters describing the cycle, ways humans negatively impact the carbon cycle, and ways they can improve it.
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 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 reinforcement. After teaching the cycles, time is spent on limiting nutrients and eutrophication in aquatic ecosystems. This commendable PowerPoint will educate and arrest the attention of your high schoolers.
