Learn how ocean currents are vital to humans and marine life. The eighth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program, focuses on ocean currents and how they affect global climate. The...

A deep ocean current circles the globe at a force that is greater than 16 times all the world's rivers combined. Groups analyze the effects of submarine topography on deep ocean current speed. They then determine how this speed affects...

Students use satellite data to see the correlation between sea temperature and sunlight in the Gulf of Maine.  In this phytoplankton instructional activity students use Excel to analyze data. 

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

For this conversion factors worksheet, students convert 15 measurements from one unit in the SI system of measurement to another unit. Students show their work and indicate the unit of measurement. Conversion factors are given.
