The fate of Persistent Organic Pollutants

With an audience of educators from 20 states, last night's webinar was to our largest audience ever. A huge thank-you to the presenters for their engaging presentations and insights!

POPs around the world
Scientist and freshman chemistry teacher Penny Vlahos presented her concept map about Persistent Organic Pollutants (also known as POPs) last night - and shared some of the hard truths about some of the man-made chemicals that travel around the globe. These POPs can be anything from pesticides to cosmetics, flame-retardant sprays or packing materials - and have been used for a variety of purposes until they (or the chemicals that they break down into) were found to be toxic.

Penny gave us a great overview of some of the sources, the transport paths that these pollutants can take to enter coastal ecosystems. During the question and answer session, she also offered suggestions for teachers who want to discuss these compounds in their schools, and detailed her proposed work with schools monitoring chemicals in the oil spill.

The right connections
Sue Klemmer, high school teacher from Camden, ME was inspired to use concept mapping when she was taking a graduate course, and first read "Learning How To Learn" by Novak and Gowin. She shared some of the teaching strategies she uses with her students when they are learning to concept map. She uses concept mapping to increase their reading comprehension - also helping them to understand both the content and their own learning. She showed several example maps that illustrate misconceptions and allow her to know what topics she needs to spend more time on. Sue also shared the rubrics that she uses to evaluate student concept maps. These resources are available on her teaching wiki. Download Sue's slides here (Power Point, 923 KB).
