3-D Cell Model Rubric (Score Sheet)
Directions: Create a 3-D cell model.
As you work through the activity use the attached rubric as a guide to earning your grade. TURN THIS
PAPER IN WITH YOUR PROJECT
Procedure
1. Use materials to build a plant or animal cell model. Your model should be three dimensional , not
flat. Follow the materials guidelines below.
2. Your model must show cellular organelles in their approximate sizes and numbers. Use the pictures
of the cell provided to know the sizes and numbers of the organelles.
3. Build your model so that the size is no larger than 1 meter by 1 meter.
4. Complete the key on the back of the paper or create your own key that you attach to your project.
5. Present to the class.
Material Guidelines


To hold your cell use boxes; plastic bags; clear plastic containers (NO GLASS).
Dry foods such as seeds, beans, nuts, pasta (NO SUGARS/FOODS THAT SPOIL).
Small items such as beads, pipe cleaners, straw, buttons, batteries, thread, ribbons, shoestrings, yarn,
elastic.
Materials such as sponges, clay, fabric, cardboard, newspaper.
(NO LIQUIDS OR GELS that can make a leaky mess).
Clay (optional)
Use your creativity and imagination.
