About these Webinars:
The ROLE Model webinars provide scientists with the opportunity to interact with educators and present their research in a non-traditional format - through multimedia concept maps created with the Concept Map Builder and presented through the Ocean Climate Interactive. [more]

About this Scientist:
Linda Kalnejais is an Asst. Professor of Oceanography at the University of New Hampshire. She researches the generation, cycling, fate, and effects of contaminants in the environment. She is especially drawn to studying the coastal zone because of the complex processes that occur in this densely populated region, and which, therefore, receives most of the contaminants carried by the terrestrial water cycle.

About this Educator:
Sharon Gallant teaches environmental science at Gardiner Area High School in Gardiner, ME, where she is also known as the "Queen of Green" for her role in encouraging students to adopt an environmental stewardship ethic. She received her M.S. in geosciences from Mississippi State University and was a participant at the COSEE-OS Educator-Scientist Climate Change Workshop at the Darling Marine Center in November 2008.

WEBINAR RECAP
Great Bay Natural Estuarine Research Reserve
Oceanographer, Linda Kalnejais, explained how unique estuaries are as ecosystems, and how important they have been to human societies: 22 of the 32 biggest cities in the world are on estuaries. As a result a significant number of pollutants enter these systems, which is the focus of Linda's work. For her talk, she focused on nutrients. These include chemicals like nitrogen, phosphorous and iron, which are necessary for the survival of organisms. However, when they accumulate in excess, nutrients can endanger the health of the organisms by creating poor water quality conditions, even dead zones. Linda's map offers links to a wealth of teaching resources.

High school science teacher, Sharon Gallant, presented an enlightening introduction to concept mapping. She explained what concept maps are and why they are such useful teaching tools. She threaded seamlessly into her talk numerous concept maps created by her students that illustrated different uses and purposes for mapping, and showed varied thinking styles and levels of understanding.
