Modeling Mitosis
Name: ___________________________________
Period:
Problem: To demonstrate that cells repeatedly divide to make more cells for growth and repair.
Background information: Mitosis is a process of cell division which results in the production of two
daughter identical daughter cells from a single parent cell. The daughter cells are identical to one
another and to the original parent cell. There are 4 phases of mitosis: prophase, metaphase, anaphase,
telophase; followed by cytokinesis.
Materials:
 4 chocolate cream filled cookies
 Ice cream sprinkles
 Twizzlers
 colored pencils
Procedure:
1. Twist the cookies apart very carefully so that you have 4 sides with cream on them, and 4 sides
without cream.
2. The cookies & cream will represent the cell; the ice cream sprinkles will represent the centrioles
and the twizzlers will represent the chromosome pairs
3. Use the cookie and the sprinkles to make models of the following phases of cell mitosis:
 Prophase
 Metaphase
 Anaphase
 Telophase
4. Use different colors of sprinkle to represent different chromosome pairs.
5. Have your teacher check your models.
6. Diagram & label your models in the data section. Labels include: chromosomes, spindle fibers,
cytoplasm, nuclear membrane, nucleus, centromere, centrioles and cell membrane.
7. Answer the questions about mitosis when you’re finished with your models & diagrams.
