Build a model of a prokaryotic cell using any material of your choice. In your model be sure to include all the structures appropriate to your cell. You may model a bacterial cell or an archaea. You will model at least 4 structures in any model.
Next, build a model of a virus using the same type of materials. You may choose any type of virus but be sure you can illustrate the key features of a virus (head shape for example).
Once complete, take multiple photographs of your models from all angles. Include these images in a document that also contains the following completed table format. You may need to add rows to your table depending on the type of prokaryote you model.
| Structure | Model Key | Function | Found in Virus | Different in Virus |
Once your model is complete, write a brief description of your cell and your virus. Emphasize features that are absent in viruses that classify them as non-living. You can refer to specific structures in your table in this explanation.
Some suggestions for 3D models include Legos, a decorated cake with candy toppings, or standard Styrofoam base with appropriate pieces attached. You can also draw or illustrate a model.

| Criteria | Ratings | Pts | ||
|---|---|---|---|---|
| Prokaryotic model provided | Model includes nucleoid, DNA, ribosomes, and cell membrane and other structures such as cilia, flagella or cell wall | Model includes nucleoid, DNA, ribosomes, and cell membrane | Model does not include nucleoid, DNA, ribosomes, and cell membrane | 3 pts |
| Viral model provided | Model includes nucleic acid, coat, shaped head, and tail | Model includes nucleic acid, coat, and tail | Model does not include nucleic acid, coat, and tail | 3 pts |
| Table is fully completed | All structures include a key and detailed function description; viral structures are also included/labeled | All structures are not fully described or functions are incomplete | Not all structures are included or viral differences are not noted | 3 pts |
| Written description | Written description fully outlines and discusses both models and emphasizes the features of viruses that classify them as non-living. Specific features of the models are referenced in description | Written description is brief or terse but does address required points | Written description is incomplete or absent | 3 pts |
