Snake Dissection (3-D Paper Dissection Model)

The Snake Dissection (3-D Paper Dissection Model) brings reptile anatomy to life in a humane, hands-on way. Formerly a longtime favorite of the Getting Nerdy collection, now part of the Inside Out Science lineup. Suitable for exploring reptile anatomy, organ systems, and evolutionary adaptations, this 3-D paper dissection model gives students the thrill of discovery—without the mess, odor, or ethical concerns of real specimens.

This snake dissection model lesson includes a student-friendly reading that explores structure and function in reptilian systems, black-line and color templates for differentiation, and a step-by-step PowerPoint presentation that walks students through coloring, cutting, and assembling their own realistic paper snake model they can “dissect” again and again. Designed to mimic an authentic dissection, this Scienstructable 3-D paper model works beautifully as a dissection-free exploration, a pre-lab preparation activity, or a summative comparative anatomy assessment. Teachers value how it highlights key reptilian features like elongated organ placement, scaly skin, and specialized digestion, while students who opt out of traditional dissections appreciate the same authentic, hands-on learning experience that’s eco-friendly and inclusive.

All Inside Out Science dissection models maintain a consistent organ color system and include templates for both sexes (where applicable), helping students visualize anatomical relationships, compare across vertebrate groups, and make deeper connections in comparative biology and evolutionary anatomy. Humane, reusable, and classroom-friendly, this Snake Dissection Model lets students study vertebrate structure and function from the inside out—no scales required. Furthermore, this model adheres to modern Three Rs standards (Replacement, Reduction, Refinement), offering an eco-friendly and scent-free experience that accommodates students opting out of traditional dissections.
