The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...

Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Students identify the different biogeochemical cycles on Earth. In this biology lesson plan, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.

Students state the physical, chemical or biological processes associated with these environments: Pelagic ocean zone, California coat Cave, Indiana Barrier island beach, North Carolina Sand dune, Dunes National Park, Colorado Wetland and...

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

Learners explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Students identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

Students examine how to use ecological analysis to animal production systems.  In this sustainable agriculture instructional activity students examine where the nutrients flow in a system and complete several activities. 

Sixth graders collect soil samples and record the location of the samples by using GPS.
