AP Biology Edible Cell Model Extra Credit Project –

Tuesday, January 4th, 2016

v  The challenge is to create the most accurate edible cell for extra credit.

v  The edible cell models must comply with the attached rubric. The goal is to create the most accurate model of a plant OR animal cell in terms of structure and be able to identify and describe the function of each structure when asked by the teacher.

v  Rules for Model Preparation

1.  The model must include all of the structures listed below and all materials used must be completely edible.

2.  The model must be three dimensional. In other words, it CANNOT be a flat icing drawing on top of a cake. However, cake can be used as a construction material.

3.  You must be able to identify each organelle on your model and describe its function without any notes during judging.

4.  The organelles should NOT be labeled on the models.

5.  The following organelles must be included in your model to receive full credit for the project.

Cell Parts to be included in the Edible Cell Project

Animal Cell

1.  Plasma Membrane

2.  Centrioles

3.  Mitochondria

4.  Golgi bodies

5.  Nucleus

6.  Nucleolus

7.  Smooth ER

8.  Rough ER

9.  Vesicles

10.  Lysosomes

11.  Ribosomes

12.  Cytosol

13.  Chromosomes

Plant Cell

All of the above EXCEPT for number 2: centrioles! Then add the following.

1.  Cell Wall

2.  Chloroplasts

3.  Vacuole

The Rubric

SCORES / 3 / 2 / 1 / 0
Accuracy of Model / Has all required 13 cell parts for an animal cell or 15 cell parts for a plant cell. / Has 9-12 cell parts for an animal cell or 11-14 cell parts for a plant cell. / Has 6-8 cell parts for an animal cell or 8-10 cell parts for a plant cell. / Has 5 or less parts for an animal cell or less than 7 parts for a plant cell.
Creativity / Highly Creative – unique ideas, colorful, high attention to detail / Somewhat creative – average ideas, colorful, some attention to detail. / Limited Creativity – not much attention to detail, parts are not distinctive, limited originality. / Lacks any form of creativity.
Knowledge of Functions / Knows all the cell parts and their functions. / Knows 9-12 cell parts and their functions for an animal cell or 11-14 cell parts and their function for a plant cell. / Knows 6-8 cell parts and their function for an animal cell or 8-10 cell parts and their function for a plant cell. / Only knows half or less of the cell parts and their functions.

A score 8-9 will earn the student 2 extra credits points on the marking period grade.

A score of 5-7 will earn the student 1 extra point on the marking period grade.

Any score below 5 will not earn any extra credit.
