COOKIE LAB
Problem: How do cookies compare to rocks?
Objectives:
A. Identify different rock types using special characteristics.
B. Identify cookies as if they are rocks.
C. Understand the Rock Cycle
D. Be able to think outside the box, be creative!
Procedure:
1.
Analyze the cookie samples. Place them into different categories based on the
characteristics you see present. Use these characteristics to determine if it would be a
sedimentary, igneous or metamorphic rock. (there are NO wrong answers). Once you decide
which rock type the cookie represents write a detailed description of the cookies and the
characteristics you saw that made you decide it was that rock type. Characteristics useful may
include: Crystal Size, Grain Size, Origin, Mineral Content, Banding, Fossils...
2.
Compile a data table and include as much information as possible.
3.
Write and answer 5 ‘thoughtful’ questions related to rocks (NOT cookies) and answer
them.
Conclusion:
You must type up a well-organized lab report which summarizes what you did in this activity.
Your report must include the following information, and be in chronological order as listed
below.

Observations: Use the ESRT to identify specific characteristics in your ‘rock’ sample that lead you to
conclude what type of rock it is and the exact Rock Name for the sample.
Observations should include: Texture, Grain Size, Crystal Sizes, Foliation, Banding, Fossils, Layers,
