2. Let’s Review, What is a rock?
1) Rock: a naturally occurring solid mixture of one or more _______ and _______ matter.
It is classified by __________ & __________________.

3. It may be hard to believe, but rocks are always changing
It may be hard to believe, but rocks are always changing. 2) rock cycle- The continual process by which new rock forms from old rock material Rocks are made through this continuous cycle that never ends. Metamorphic to sedimentary to igneous… Igneous to Metamorphic…

4. Rock Cycle Basics Let’s start Basic: Overview of 3 Rocks and their life in the Rock Cycle!

5. Rocks may follow various pathways in the rock cycle
Rocks may follow various pathways in the rock cycle. As one rock type is changed to another type, by variables. 3) variables of the rock cycle: time, heat, pressure, weathering, and erosion may alter a rock’s identity. The location of a rock determines which natural forces will have the biggest impact on the process of change. For example, rock at the Earth’s surface is primarily affected by forces of weathering and erosion, whereas deep inside the Earth, rocks change because of extreme heat and pressure.

6. There are many ways to review this process, from simple to complicated.

The sequence of events in the rock cycle depends on variables, such as time, weathering & ________, ________ & pressure, and heating & _________, that change the rock material. 3)
_________ and ________ are two characteristics that scientists use to classify rocks. •
The composition of a rock is determined by the __________ that make up the rock.
The texture of a rock is determined by the ________, _______, and positions of the grains that make up the rock.

12. Rock Cycle Simulation Part I - Making Sedimentary Rock (___________)
Goal: To simulate the rock cycle using crayons to represent rocks.
Materials:
Crayons (Igneous Rock)
Coin
Aluminum Foil Square
Paper Towels
White squares of paper
Part I - Making Sedimentary Rock (___________)
Weathering and Erosion
In nature, rocks are broken down by the forces of nature. In this
simulation, the crayons represent rocks and the coin
represents weathering (wind, sun, ice, rain)
that causes rocks to break down into smaller pieces.
1. Weather your rock. In other words, use a coin to shave your crayons into
small pieces (sediment) on a square of paper. One color per person!
One person per table will use a pencil sharpener instead.

13. 2) Erode the rock (moving the sediment from one place to another) by collecting the desk partner’s individual shavings and placing them together on a white paper towel. Be as neat as you can.
3. Answer these questions about your weathered and eroded rocks: (Use your science tech terms!)
a. What do the different colored crayons represent & why?
b. Are the fragments (sediment) all the same size or shape? Describe.
c. Would this be true of rock fragments in nature? Why/Why not?   
d. What are some of nature’s tools used to erode rocks?

14. Deposition
1. Once rock fragments have been created, they are usually moved by some force of
nature, like gravity, and dropped in a new location (DEPOSITION). Here you will act as a depositional force.
2. Take your paper towel with crayon shavings and pile you and your lab partner’s rock fragments in a neat pile in the center of the aluminum foil. You have just moved and lain down (DEPOSITED) the rock fragments.
3. Answer the following questions:
a. Describe the shape and size of spaces between your rock (crayon) pieces. Are they large/small and irregular/regular shaped?   
b. How does nature move and lay down (DEPOSIT) rock?

15. Compaction / Cementation
1. This part of the simulation requires you to understand the cementation process. Spaces between the fragments are reduced in size by pressure (COMPACTION) and filled in with cementing agents (CEMENTATION). This simulation will not add cementing agents. It will only simulate compaction. The compaction process occurs as sediment layers are continually covered by new layers of sediments. The lower layers become compacted by the weight of the new layers above.
2. Carefully fold the loose layers of crayon shavings inside the aluminum foil. Make a closed packet!
3. Bring your folded packet to the front of the classroom for your teacher to compact your eroded rocks (crayon shavings). Use one red science book to push down on your foil packet. This is your compaction/cementation.
4. Answer the following questions:
