This is a radio interview with WESA (Pittsburgh Public Radio) on "The Confluence" with PolarTREC teacher Mike Penn and Kevin Gavin. Penn's interview starts at approximately 18:05.
Using photos from a variety of websites, including the PolarTREC and SCINI websites, students will identify organisms to phylum and/or class level (e.g. polychaetes, starfish, brittle stars, sponges) and then research the primary foods that these organisms eat. They will then develop a simple food web for these organisms.
