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 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...

Students 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...

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 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.

Learners examine how to use ecological analysis to animal production systems.  In this sustainable agriculture lesson 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.
