Students gain skill in the design, implementation, and reporting of a scientific research project using the scientific method. They set up an experiment to determine the effect of adding the Rhizobium bacteria to one group of legume seeds. Students plant seeds in containers containing vermiculite and after the seeds germinate, they take the pots home to continue the project.
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.
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.
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, biomes, biodiversity, and the flow of energy. The second section focuses on nutrient cycles. The final installation examines population dynamics with an emphasis on problems accompanying overpopulation. The font may be considered "cute." This is easily altered if this is not to your liking. Otherwise, this is a terrific resource!
An in-depth introduction to biological classification is presented at the opening of this presentation, dividing life into six kingdoms. Although it does not address the currently accepted level of domain, it is an outstanding exploration of the criteria for each kingdom and the unique characteristics of archaebacteria, eubacteria, protista, and fungi. Diagrams, graphics, and high-quality color photos enhance learning. Watch out for the final fungi photo; It is disgusting!
The nitrogen cycle is the focus of a well-designed science lesson plan. 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.
A lot of learning is packed into these 23 questions about ecosystems. Advanced biology classes apply their knowledge of communities, productivity, biogeochemical cycles, and human impact on the environment by writing short answers for each. Assign this as homework for your environmental, ecology, or AP biology classes.
Let there be light! When your physics learners take this midterm exam, light will be their focus. They will show what they know about electromagnetic waves, interference, refraction, reflection, lenses, prisms, and more! The test is comprised of eleven vocabulary matching questions, eight multiple choice, and three complex problems to solve.
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 plant adaptations when nutrient conditions are low. There are diagrams and flow charts to help explain the concepts. The 53 slides of information will require a few class sessions to dispatch.
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, phosphorus, and nitrogen cycles. Middle and high schoolers fill in the blanks to test their understanding of these mechanisms.
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.
