I participated as an invited speaker for the 2020 Action Network Speaker Series on plastic. I had the opportunity to teach 3rd graders at Chautauqua Elementary School on Vashon Island about marine biology, how different marine organisms ingest microplastics, and how microplastics can pass through different ocean habitats and trophic levels.

The 3rd graders were several decades younger than my usual audience and it was a fun challenge to create a single interactive & hands-on activity that spanned multiple concepts. Some students acted out roles as orcas and sea lions while others were worms and mussels. I’ll let you guess which animals they were more excited by!
