Learning about living things should feel just like the things you are studying… “alive”. Activities should be hands-on, not just flat on a worksheet, and they should always aim to demonstrate the interconnectedness of science. Inside Out’s 3-D paper dissection models help students to connect the living thing to the concept, allowing students to explore anatomy and biology with an interactive, eco-friendly twist. They’re mess-free, reusable, and a fantastic tool for making abstract concepts tangible. All this to say, dissection models aren’t just for your classification and human body units! Here’s how you can incorporate paper models into all seven major life science topics with three easy to implement activities you can adapt to any grade level. Check it out!
Scientific Method
Paper models can be used as the “specimen” for a real investigation. Have students practice forming questions, designing experiments, measuring and collecting data using their models. Here’s a few ideas to try:
⭐ Observation Challenge
-
Before learning about an organism, give students an unassembled model and have them write only observations — no guesses — about its parts.
- Then have students think-pair-share and come up with some inferences about the function of each part based on their observations.
-
Once students build the model, have them compare their results to the reality of the structures. Discuss how careful observation leads to better hypotheses.
⭐ Hypothesis Testing
-
Pose a question like: “Does the size of the organ affect its function?” or “Does the length of the small intestine impact nutrient absorption?”
-
Have students create a hypothesis, then research and present their findings with evidence from the model.
⭐ Variable Swap Investigation
-
Give each group of students a paper model, then pose a question like “does the number of folds in the small intestine impact nutrient absorption?” or “if all the chambers of the heart are the same size, will the heart pump more efficiently?”
-
Have students change one variable on their model to address the question (draw larger/smaller organs, add/delete features, alter connections using sticky notes).
-
Students can write a hypothesis about how the change would affect the function.
- Each group presents their ideas to the class for a great discussion about how altering one variable at a time affects overall outcomes.
Cells
Paper models show the whole organ or organism, but that doesn’t mean you can’t take it to the cellular level. Try these activities to show how cellular function contributes to the overall function of the entire organism.
⭐ Scale Connection
-
Have students assemble an organism and choose an organ or another structure from their model.
-
Students then draw what they imagine the cells inside the structure might look like, based on the function of the structure.
-
To sum up the activity, you can create microscope stations where your kiddos can observe cells from those structures and compare their hypotheses with the real images.
⭐ Organelle Match-Up
-
Give each student an organelle to research and have them present how it relates to an organ in the model (e.g., mitochondria as the “powerhouse” for muscle cells in the heart).
⭐ 3-D to 2-D Translation
-
Have students choose and trace an organ from the model, then in a larger diagram, have them draw and label its cellular layers as if creating a textbook diagram.
Human Body
This should be a no-brainer. Paper dissection models are chock full of organs and organ systems and can be the perfect introduction or summation to your human body unit. While the organ systems may not look exactly the same, they’re great for comparative anatomy discussions and for exploring how and why the body is arranged the way it is.
⭐ System Connections
-
Compare two models and have students notice the similarities and differences between the organ systems.
-
Then have students map out how certain functions are carried out: for example, respiration in a grasshopper versus respiration in a frog. How are they alike, how are they different? What structures are the same? What structures are different? What path does air take through each?
⭐ “If This Broke…” Scenarios
-
Present a case study to the class where one organ or organ system is not functioning correctly or is injured.
-
Have students use the model to explain the cascade of effects throughout the body.
⭐ “Life Without…” Creative Writing/Drawing Activity
-
Assign each group a specific organ of the body, with the assumption they have prior knowledge about its function.
- Have students write a short narrative, create a comic strip, or draw and label a diagram explaining what life would be like without it.
- Let students share their findings with the class to spark some great discussions.
Classification
Having an arsenal of models at your fingertips is perfect for your classification unit. Students can compare organisms from across the kingdoms, across phyla and even within the same taxonomic groups.
⭐ Sorting Challenge
-
Provide students with several different types of organisms and have. them classify them according to their kingdom, phylum, class, etc.
-
Create a Venn diagram showing which traits each organisms share.
⭐ Traits Detective
- Provide your kiddos with a few different paper dissection models (frog, fish, mammal, etc.).
-
Prepare a traits checklist with observable features such as: number of limbs, presence of lungs or gills, skin covering (scales, fur, skin), type of heart (2-, 3-, or 4-chambered), reproductive method (egg-laying, live birth), etc. and provide it to your students.
- Have students carefully examine their model and record each trait on their checklist.
-
Once they have their traits, groups can share their findings with the class. Compile their lists on the board.
-
As a whole class (or in small groups), students work to decide which organisms share traits and how they could be grouped.
⭐ Missing Link Debate
-
Give students a fictional “mystery model” with a mash-up of traits and have them figure out where it fits in the classification system.
Evolution
Models are great at helping students gather evidence of how mutation and adaptation lead to changes over time, establishing a record of evolutionary history. They’re also perfect for comparing and contrasting structures which help us to trace back to a common ancestor.
⭐ Adaptation Hunt
-
This activity has students identify features/adaptations in a model that help the organism survive in its environment. You can choose to guide students in this hunt by selecting a specific function (like movement or reproduction).
-
Once they’ve identified their feature(s), have them compare their findings to other species’ models.
⭐ Fossil Reconstruction
-
Have students begin by selecting a model and have them research a brief timeline of evolution of that organism, looking for the advent of major structures or changes in behavior.
-
At each major junction of evolution, have students hypothesize what the organism looked like at that time and why.
-
Have them recreate the fossil record by drawing what the organism looked like at each major stage.
⭐ Comparative Anatomy Race
-
Review homologous structures (e.g., forelimbs) and then have students use models to compare those structures across various species and discuss their evolutionary significance.
Genetics
You might think that paper models aren’t a great fit for teaching genetics, but they actually make a great tool for developing Punnett Squares or visualizing mutations.
⭐ Trait Tracking
-
Students choose several traits from their models and create Punnett square problems based on those traits.
- Have students trade their problems and solve them.
⭐ Mutation Scenarios
-
Give students a “mutated” version of a model part using a paper alteration.
-
In groups, students discuss how that mutation would impact the organism’s survival.
⭐ Build Your Own Hybrid
-
Let students get creative by combining parts from two models to create a hybrid organism.
-
Have them explain the genetic reasoning behind the combination and how the new hybrid will be better suited for its environment.
Ecology
How do all of these things work together? Models are great tools for exploring habitats and exploring an organism’s role in various ecosystems.
⭐ Food Web Build
-
For each model, assign them an ecological role as a producer, consumer or decomposer.
-
Connect each model in a web using string. Add in any other organisms that might fit into the food web.
⭐ Habitat Match-Up
-
Create habitat cards showing various places where organisms can live.
-
Provide students with models and have them examine them, noting various traits that may indicate where they might need to live.
-
Have students match the models to each habitat based on their adaptations and present to the class why they made their choices.
⭐ Model Ecosystem Mapping
-
Provide each group of students with a model and a large sheet of chart paper divided into three labeled sections: trait (from the model), function (what it does for survival), and the ecological connection (how it affects the ecosystem).
-
Have students choose at least three traits from their model to list on their sheet (ex. frog: moist skin, lungs, hind legs)
- Students then identify the function of those structures and then brainstorm how that functions matters in the ecosystem (ex: moist skin – gas exchange – must live in moist environments – indicator of ecosystem health).
- Once they have their ideas, they’ll populate their chart paper and then come together with other groups to create a master “map” showing how different organisms’ anatomical traits connect to the balance of the overall ecosystem.
Why This Works
A lot of life science is unfortunately memorizing facts about living things, and sometimes that info just doesn’t stick. By combining hands-on 3-D models with core science topics, students get a multi-sensory learning experience that builds both their content knowledge and their curiosity. They aren’t just memorizing — they’re investigating, connecting, and thinking like scientists. It’s a win-win.
