Rock Cycle “Crayon” Lab Activity Questions
PART A:
Paste the “close up” photograph of your lab partner’s hands while
they perform the process of weathering the rock/crayon
below. Adjust the size of the photo as necessary. (4)
PART B:
Paste the “close up” photograph of your deposited sediment
below. Adjust the size of the photo as necessary. (4)
PART C:
Paste the photograph of your newly created clastic sedimentary
rock below. Adjust the size of the photo as necessary. (4)
Part A-C Analysis Questions (Please respond with a complete
sentence claim and supporting details):
1. In part A, you used the file to “break down” the crayons into
smaller pieces. Which type of weathering (mechanical or
chemical) does this represent? Be sure to explain the
reasoning for your response. (5)
2. The crayon shavings represent sediment. In part C, what has
to happen to the crayon sediments before it becomes rock? Be
sure to explain the processes in detail in your response. (5)
PART D:
Paste the photograph of your newly formed metamorphic rock
below. Adjust the size of the photo as necessary. (4)
Part D Analysis Questions (Please respond with a complete
sentence and supporting details):
1. How is the metamorphic rock process of pressure
represented in Part D of this lab? Be sure to explain the
reasoning for your response. (5)
2. How did the pressure that was needed to create the
sedimentary rock differ from that which was needed to
create the metamorphic rock? Be sure to explain the
reasoning for your response. (5)
PART E:
Paste the photograph of the newly formed igneous rock below.
Adjust the size of the photo as necessary. (4)
Part E Analysis Questions (Please respond with a complete
sentence claim and supporting details):
1. How are the igneous processes of melting and hardening
(solidification) represented in Part E of this lab? Be sure to
explain the reasoning for your response. (5)
2. Using the crayon example from this lab, describe how it is
possible for this “igneous rock” to change into another type
of rock (igneous, metamorphic, or sedimentary)? Be sure to
explain the reasoning for your response. (5)

Going Further Questions
1. Find Bergen County on the Geologic Map of New Jersey.
Which physiographic region is Bergen County a part of?
What specific rocks are most commonly found in this region
and what rock category are they a part of (igneous,
sedimentary, metamorphic)? Make sure that your response
includes an answer for each part of this question and
provides claims along with appropriate evidence. (5)
2. Looking at the maps, what are the two most common rocks
found in the New Jersey Highlands? Pick one of these rocks
and clearly explain the processes of the rock cycle that led
to their formation in New Jersey’s geologic past. Make sure
that your response includes an answer for each part of this
question and provides a claim, evidence, and reasoning. (5)
