Understanding Marine Ecosystems and Classification

Erin Lomax, an education specialist at the Smithsonian Marine Ecosystems Exhibit, introduces a module on using dichotomous keys, aimed at students in grades 5-8. The module includes a video overview, a dichotomous key activity for identifying seashells, and a photo key for those without seashells. Erin explains the importance of classifying organisms and provides examples, such as distinguishing between two similar shrimp species using a dichotomous key. The video concludes with instructions for the activity and contact information for further questions.
