Interactive Fish Diet Analysis Activity
I originally designed this activity for a science convention aimed at children from underrepresented backgrounds in STEM. As a volunteer hosting an "activity booth," I wanted to create something highly interactive, adaptable to different age groups, and reflective of my work. The activity features paper Pacific cod that can be "stuffed" with cut-out prey items in various stages of digestion. These prey include benthic invertebrates, crab, and fish—some whole, others in parts (such as bones, jaws, claws, setae, otoliths), mimicking the types of remains we commonly find in actual stomach samples. Children spread the "stomach contents" on a table and use a mock key I developed to identify the prey, then record their data and measurements. I wrap up the activity by inviting students to share why they think this kind of work is important, allowing space for questions or reflections. For toddlers, the activity can be a simple matching game, while for older students, it incorporates math and critical thinking. Facilitating this activity at conventions, school science nights, class sessions, and fairs has sharpened my science communication skills. As an educator in these settings, it’s my responsibility to ensure the activity is both engaging and educational for a diverse audience. I’ve found that the more I understand each child’s unique needs, the more deeply they are able to engage with the activity.
