Explore echinoderm anatomy from every arm and angle! Formerly part of Getting Nerdy, this Sea Star (Starfish) Dissection Model has found its new home at Inside Out Science, where humane, hands-on learning meets classroom creativity. Perfect for studying echinoderm structure, starfish anatomy, and water vascular systems, this 3-D paper sea star dissection model helps students investigate organ function and radial symmetry in a clean, eco-friendly, and budget-friendly way.

This sea star dissection model lesson includes a student-friendly reading that introduces in-depth echinoderm anatomy and physiology, black-line and color templates to support all learning levels, and a guided PowerPoint presentation that takes students step-by-step through coloring, cutting, and assembling their own realistic, reusable paper sea star.

Created to mimic a real dissection, this Scienstructable 3-D paper model can be used as a dissection-free exploration, a pre-lab preparation tool, or a post-lab comparative anatomy assessment. Teachers love how it highlights echinoderm features such as tube feet, radial canals, and digestive systems, while students who opt out of traditional dissection enjoy a hands-on, authentic anatomy experience that’s kind to creatures and the planet.

All Inside Out Science models (formerly Getting Nerdy’s Scienstructable Dissection Models) maintain a consistent organ color system and include templates for both sexes (where applicable), allowing students to visualize anatomical relationships, build comparative biology connections, and understand the essential relationship between structure and function in living organisms.

Reusable, humane, and beautifully detailed, this Sea Star Dissection Model lets students explore ocean life and learn from the inside out—one arm at a time.
