Inside the Animal Cell – How I Built This 3D Model That Brought Science to Life
SCIENCE
In 7th grade, I created this 3D model of an animal cell, and it helped me understand something a textbook never could: how cells actually work as tiny, organized machines inside our bodies.
I made this for a school science project, and while I already enjoyed biology, this hands-on experience helped me visualize and memorize every organelle. It wasn’t just a project; it was my first real step into thinking like a future scientist.
What This Project Teaches Students
This cell model project is a core part of the middle school life science curriculum. It’s usually taught during a unit on cells and body systems.
Through this project, students learn:
The major parts of a cell (organelles) and their functions
How a cell is structured and organized
That each part of a cell has a job, just like parts of a city or body
How to label biological structures clearly
Creative thinking + hands-on application of biology concepts
It’s a perfect blend of STEM + creativity and gives students a fun way to retain vocabulary through design.
Key Learning Outcomes (7th Grade Science Standards)
Differentiate between the nucleus, mitochondria, ER, ribosomes, etc.
Understand how cells are the building blocks of life
Use models to describe structure and function
Practice labeling diagrams, which prepares students for higher-level science
Supplies I Used to Build This Model
You can use many different materials, but here’s what I used to make mine:
Material Use: Foam half-sphere (blue), Base for the cell body, Foam or clay (various colors) to shape organelles (Golgi body, mitochondria, etc.)Toothpicks + paper labels For name tags Paint + markers To add color and definition Hot glue or craft glue To stick everything in place Black base ring To hold the model upright
Everything was easy to find at craft stores like Michaels, Walmart, or even Amazon.
Final Thoughts
This project made me appreciate how every part of our body starts at the cellular level. It’s one thing to see a diagram, but building the structure yourself helps you remember it, and more importantly, respect how complex and amazing biology is. If you’re a student working on this now, take your time and be creative. It’s not just a school project, it’s your first chance to build something that exists inside you.
