Dive into arthropod anatomy! This Crayfish Scienstructable 3D Dissection Model ® now makes its home at Inside Out Science, where humane, hands-on learning takes center stage. Perfect for introducing students to arthropod structure and function, this 3-D paper dissection model brings freshwater biology to life in a creative, eco-friendly, and stress-free way.
This crayfish dissection model lesson includes a student-friendly reading that explains major organs and systems, color and black-line templates for differentiated learning, and a step-by-step PowerPoint presentation that guides students through coloring, cutting, and assembling their own realistic 3-D crayfish. Students will see exactly where to cut, what to look for, and how each organ connects to the bigger biological picture—no lab prep or cleanup required.
Designed to mimic a real dissection, this Scienstructable paper model works beautifully as a pre-lab prep activity, dissection-free exploration, or comparative anatomy assessment. Teachers love how it helps students visualize arthropod systems—like the open circulatory system, exoskeleton, and segmented body plan—while students who opt out of traditional dissections still gain an authentic, tactile learning experience.
All Inside Out Science dissection models use a consistent organ color system and include templates for both sexes (where applicable), allowing students to compare internal anatomy across species and make meaningful connections through comparative biology.
Humane, reusable, and richly detailed, this Crayfish Dissection Model helps students grasp invertebrate anatomy in a way that’s clean, kind, and unforgettable.
