This film, produced by SEATOR walks students through how toxins that cause Paralytic Shellfish Poisoning get into your food and how the Sitka Tribe of Alaska has created a program to monitor HABs and toxins throughout Southeast Alaska. The film shows how to properly take care of shellfish you’d like to get tested, and how to deliver those shellfish to the Sitka Tribe of Alaska’s Environmental Research Lab.

Alaska Sea Grant Seas & Watersheds: Ocean and Beach Food Webs
In this unit from the Alaska Seas & Watersheds Curriculum, students investigate marine and intertidal food webs, then collect and observe plankton, and observe food web interactions during a beach field trip. After the field trip, students observe plankton using microscopes and do research to extend their learning about food chains and webs. They construct a model of a food web based on their research and evidence collected on the field trip.
Bigelow Laboratory: Fitting Plankton Into the Food Web
In this lesson from Bigelow Laboratory, students learn about the basics of food webs and trophic levels. Then they compare more familiar terrestrial food webs with marine food webs, using cards with information about various marine organisms to create their own model of a food web.
