Nitrogen Cycle-Stream Side Science
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...
Curated OER
The Nitrogen Cycle
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...
Curated OER
Nitrogen Fixation, OR What a Gas!
Learners illustrate the adaptation and co-evolution of organisms. They examine set up an experiment to determine the effect of adding the Rhizobium bacteria to a group of legume seeds.
Curated OER
Dynamics of Ecosystems
A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...

Classroom Aquaponics: Exploring Nitrogen Cycling in a Closed System
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...
Curated OER
Biochemical Cycles
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,...
Curated OER
Nitrogen Fixation, OR What a Gas!
Young scholars 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...
Curated OER
The Nitrogen Cycle
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...
Curated OER
Photosynthesis
In this photosynthesis worksheet, students complete 20 various types of questions related to photosynthesis. First, they match each description in the first column with the correct vocabulary term in the second. Then, students explain...
Curated OER
Matter and Energy
In this matter and energy worksheet, students will complete 10 questions about the transfer of energy through a food chain, the steps of the water cycle, and how the nitrogen cycle works.
Curated OER
Biochemical Cycles: Recycling Carbon and Nitrogen
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.
Curated OER
Bacteria: Friend or Foe?
Students examine a variety of environmental and industrial roles of bacteria. explore where bacteria can be found and distinguish bacteria from other organisms.
