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...

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...

Students 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.

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...

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...

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...

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 examine a variety of environmental and industrial roles of bacteria. explore where bacteria can be found and distinguish bacteria from other organisms.
