I know… I’ve been where you are. You want to give your students the excitement of a real dissection — minus the budget headaches, chemical smells, and risk of finding a stray specimen part under a desk three days later thanks to the chaos of dissection days. That’s where hands-on paper dissection models come in. Dissection can be hard just in and of itself, and I get it… and then there’s all the other stuff…
- Maybe your school can’t afford enough specimens for every student, or even enough for you to dissect in groups.
- Maybe there’s a few kids in your class who refuse to or can’t participate for personal or religious reasons.
- Or maybe you’re a homeschool parent who’d love to bring real science into your house without wearing all the hazmat gear and disposal nightmares.
It’s for these reasons and more that Inside Out Science continues to design paper dissection models for every learner. The hands-on, anatomically accurate experience you crave, with the ability to be used anytime, anywhere. Now you can give your students an authentic, interactive anatomy experience without the mess, expense, or time constraints of traditional labs.
What’s Inside a Paper Dissection Model Lesson
What do you get with your purchase of one of Inside Out’s hands-on paper dissection models? Great question! Each lesson comes with everything below and is created to mimic a real dissection process from start to finish – all the way down to how the organs are layered and how you would cut open a real specimen. IOS models allow students to learn the internal and external anatomy of an organism through:
-
Student-friendly readings that explain structure and function or each organ within the organism in depth
- Differentiated graphic organizers that are both blank and prefilled
-
Black-line and color templates for each paper model, perfect for differentiating by ability level and helping out your kiddos with executive function deficits
-
A guided PowerPoint presentation that walks students step-by-step through coloring, cutting out, and assembling their model
-
Extension questions that push critical thinking and bring in real-world connections
The best part? Each model comes with organs that apply to both male and female organisms, so you can have your students choose which they’d like to assemble. Every model uses the same organ colors across species so students can instantly see anatomical relationships between organisms, creating a true comparative anatomy experience. And since the models are reusable, students can “dissect” them over and over again without a single scalpel blade.
Use them for:
-
Dissection-free exploration for those who opt out
-
Pre-dissection preparation so students know where to make incisions and what they’re looking at throughout their entire experience
-
Summative assessments for anatomy units in class or at home
Why Teachers (and Students) Love Them
Mess-Free Learning
Dissections are one of those milestone activities that all students either look forward to or dread when they hit middle school; however, they can be a lot. From the smell of preservatives to the scramble for goggles and gloves, making sure there’s only one pair of hands in a tray at a time, to trying to figure out what you’re actually looking at – there’s plenty that can distract from the actual learning.
With hands-on paper dissection models, the focus stays on anatomy—not cleanup. And when dissection day finally arrives, your kids know what they are looking at and where to find it. One middle school teacher said that after switching to paper models for prep, “there were no groans, no wrinkled noses, and definitely no ‘flying organs.’ Just kids leaning over their desks, debating which part of the circulatory system went where.”
Friendly to Small Budgets
Specimens, gloves, replacement blades, trays – it all adds up quickly. Imagine a world where you buy a specimen ONCE and reuse it year after year. That’s the beauty of paper models – they only require a printer, some paper, glue and scissors – standard classroom supplies. You can even laminate models before assembly and reuse year after year, saving hundreds over time.
A homeschool parent once said she used a model as part of her science portfolio and it doubled as a beautiful work sample to share with her district contact. “It looked so good,” she laughed, “it almost felt like cheating.”
Environmentally Conscious
How about not having to harm any animals, avoid the chemicals, and the subsequent disposal of all the byproducts of dissection? When dissection isn’t always necessary, paper models allow you to bypass the animal harvesting and skip the preservatives entirely – no formalin, no phenol, no chemical waste. Finished models can be recycled, so your “lab waste” is just a stack of colorful paper.
Anatomically Accurate
These aren’t just arts-and-crafts projects. They’re anatomically correct, meticulously researched models, complete with organs layered and oriented exactly as they are in the real organism.
That accuracy means students can compare multiple species and see how structures evolve across different forms of life. Boom. Comparative anatomy at your fingertips.
Flexible for Any Teaching Situation
Whether you’re using them before a live dissection, as an alternative for students who opt out, or in place of dissection altogether, these models adapt to your needs.
One teacher said she used them with her 7th and 8th graders before an actual lab:
“By the time we started dissecting, students knew exactly where to cut and what they were seeing. It completely changed the pace and quality of our lab time.”
Notebook-Friendly
Every model folds up to fit into a folder or a spiral or interactive notebook. No missing pieces. No lost instructions. Just a complete anatomy lesson that students can revisit anytime. Over the years, I often have students reach out telling me that they still have their model from when they were in seventh grade. These things make the time capsule, every time.
Teacher Tips: Getting the Most Out of Hands-On Paper Dissection Models
📌 Tip #1: Pair the model with real-world visuals.
Even if you’re not doing a live dissection, you can show students photos or videos of the real organism so they can make the connection of the paper version to authentic anatomy.
📌 Tip #2: Make it a team sport.
Have students work in pairs or groups throughout the process. Talking through the build (“Wait, isn’t that the liver?”) helps to cement their understanding.
📌 Tip #3: Use consistent color coding.
Since IOS models keep organ colors/systems consistent across species, creating a classroom “color key” poster can help make systems instantly recognizable.
📌 Tip #4: Add compare-and-contrast challenges.
Have students compare one completed model to another species, analyzing how anatomy changes based on diet, habitat, or evolutionary adaptations.
📌 Tip #5: Turn it into a lab practical review.
This was a staple in my lab practicals to ensure students did the work on the model before the actual dissection. As you set up the real specimen, add a few finished models into the rotation as stations, number different structures, and have students identify each part and its function.
📌 Tip #6: Keep a “dissection notebook.”
Encourage students to collect all models in their interactive notebooks – by year’s end, they’ll have their own personalized anatomy reference guide. How cool is that?!
The Result?
Instead of spending days and days just teaching students how to dissect, you can really hone in on what they need to know – connecting form and function.
Students end up talking about organ systems, not just “eww, that’s gross.” One teacher shared that listening to her students debate the function of a certain organ was “one of those rare classroom moments where you just stand back and smile.”
With paper dissection models, you can teach any organism – from earthworms to more complex vertebrates – and give every student a chance to explore biology in a way that’s humane, budget-friendly, and easy on the planet.
