I built WRA STEM Kits because I want to help students learn science by holding it in their hands, not just reading about it in a textbook. I designed the kit to be affordable and reusable, so that as many teachers and students as possible, anywhere in the world, can use it in their classrooms.
A plant cell you can take apart.
A 12-piece, 3D printed plant cell model for middle school. Students take it apart and rebuild it to explain how each structure contributes to the function of the cell as a whole.A 12-piece, 3D printed plant cell model for middle school science.
Plant Cell Kit · Grades 6–8 · Designed to align with Next Generation Science Standards* MS-LS1-2
12 custom-designed, 3D printed pieces.
Each organelle sits in its own custom-designed slot. Students lift a part out, name it, explain its job, and set it back: a working model of the cell as a system of parts.Each organelle sits in its own custom-designed slot, held by magnets.
Reusable by you, and by the classes and students to come.
Why I built it
The quick rundown
- The kit
- 12 pieces11 cell structures, all custom-designed and 3D printed
- Reusable
- For yearsNothing gets used up, so one kit serves class after class
- For
- Grades 6–8Middle school life science
- Standard
- MS-LS1-2Designed to align with the NGSS
- Comes with every kit
- Teacher toolsStandards AI, and a worksheet generator for middle school science, grades 6–8. A worksheet editor is coming soon.
- Named to align with the NGSS
- The nucleus, chloroplast, mitochondrion, cell membrane and cell wall are the five parts MS-LS1-2 names, and the kit uses the same names.
- Each worksheet
- 3 pages + answer keySix sections, from labeling the cell to short written answers. Every question uses only the five structures named in MS-LS1-2 and comes from a fixed bank of 43.

- How it fits the NGSS
-
Students build and use a model. MS-LS1-2 asks students to “develop and use a model” of a cell. The kit is that model: they take it apart, put it back together, and explain what each part does.NGSS practice: Developing and Using Models
Every part has a job. Each structure in a cell does something specific, and the cell membrane controls what goes in and out. Each piece of the kit is one of those structures.NGSS core idea: LS1.A Structure and Function
The parts work as one. A cell works because its parts work together. Fitting each piece back into its slot shows how the parts make up the whole cell.NGSS crosscutting concept: Structure and Function
- Where things stand
- The kit is printed and the worksheet generator works. Before any student uses them, a science teacher will check every question. Neither has been tried in a classroom yet.
