Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of animal cells, and shows them the importance of being able to construct a tangible model of something that is otherwise difficult to see.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standard Network (ASN), a project of JES & Co. (www.jesandco.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.
Click on the standard groupings to explore this hierarchy as it applies to this document.

- colored pencils
- tape and scissors
- different colored paper
- Animal Cell Coloring Sheet, one per student, available at http://www.biologycorner.com/worksheets/cellcolor.html

|cell membrane:||A semi-permeable membrane that encapsulates a cell's cytoplasm.|
|membrane protein:||A protein molecule attached to the membrane of a cell or organelle.|
|organelle:||A structure in a cell that performs a specified task or function. Found in eukaryotic cells.|
Before the Activity
- Gather materials and make copies of the Animal Cell Coloring Sheet, available at http://www.biologycorner.com/worksheets/cellcolor.html.
- Obtain from the University of Utah's Teach Genetics website the instructions and templates for the Build-a-Membrane activity at http://teach.genetics.utah.edu/content/begin/cells/. Make enough copies of the templates for all students. Either print out the instructions, or have students read them online.
With the Students
- Distribute the materials and worksheets for the cell coloring page.
- Make sure all students read the instructions carefully. This is a wonderful student-directed activity, so let them investigate and only provide instructions and guidance as they ask questions.
- Once students have completed the coloring portion, divide the class into small groups and direct them to the Build-a-Membrane exercise, following the instructions found at http://teach.genetics.utah.edu/content/begin/cells/print/BuildAMembrane.pdf.
- Conclude by assembling together the "membrane-pieces" with those from other groups in the class to form a large cell membrane model. Ask students the Investigating Questions.
- What are some of the structures within a cell?
- What are their functions?
- What is nanoscience, and how does it relate to studying cells?
- Why is it important for engineers to build models of cells?
