Oreo Cookie Lab – Mitosis
Supplies:
6 Oreo Cookies
Sprinkles
Chromebook
Paper Towels
Scissors
Objective: Be able to model the phases of Mitosis and understand what occurs during each specific phase.
Procedure:
1. Have one person from your group obtain supplies for the Oreo Cookie Lab.
2. Use Chromebook to view the diagrams of Mitosis
3. Assign jobs to each member of the group:
a. Sprinkle Sorter- In charge of picking out the necessary sprinkles.
b. Sprinkle Placer- In charge of placing the sprinkles on the icing of the Oreo Cookies and
spreading icing.
c. Director- In charge of using Chromebook to make sure the sprinkle placer is putting the
sprinkles in the proper place.
4. Start by gently twisting off one of the “outside” chocolate cookies from every Oreo cookie leaving only
the “middle” or white icing and a chocolate cookie on the bottom.
5. Now you will be creating models for every phase of Mitosis and Meiosis included below (think about
genetic recombination and crossing over):
- Interphase (use icing to write 2n on icing of 1 Oreo)
- Mitosis
o Prophase (1 Oreo)
o Metaphase (1 Oreo)
o Anaphase (1 Oreo)
o Telophase (1 Oreo and use 1 of the leftover “outsides” and spread icing in between the two
cookies)
o Cytokinesis (2 Oreos – end product with two cookies)
6. Put the Oreos on the next page under the correct phase and write a description of what is happening
during that phase. You will need to take a picture with your Chromebook of the Oreos and description
and will be using this for your lab reports.
7. Once you have completed the lab and taken the picture and shared it with all group members, you may
eat your Oreos and cleanup your area.

Oreo Cookie Lab Questions:
1. During what phase do the sister chromatids move to opposite sides of the cell?
2. How many chromosomes are there in each cell when you are done?
3. What are the benefits of Mitosis?
4. What is the end result of Mitosis?
5. When is the DNA/chromosomes copied?
6. What is chromatin?
