An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability

Students study the advantages and disadvantages of bacteria.  In this bacteria lesson students draw and label the different types of bacteria.

Two pages of questions provide a brief overview of plant nutrition. Biology or botany brainiacs describe how plants absorb and transport nutrients, they explain the role of different bacteria, and they describe a variety of unusual...

How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...

This plant structure and function PowerPoint addresses the main organs and the factors that affect its development as well as going into detail about the specializations at a cellular level.   The cell functions and system...

We wish you a happy, healthy, and phosphorus school year! A video explains the importance of getting the nutrients that are needed and focuses on the nitrogen and phosphorus cycles. It includes discussions on the importance of...

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this...

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...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.

Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the...
