Corn starch (like silt)

Dry ground coffee �(to simulate organic matter)

Tools:

• Spray bottle
• Cups to sort out your scoops
• A piece of cardboard roll to build the rock IN
• Piece of Newspaper to build the rock ON

Part 2: Diagram

Make a diagram of what your rock looks like INSIDE the paper towel roll.

• Label all the ingredients
• Put them in the order you layered them
• Make different patterns or textures for each substance.

1. Write period # and table # (or one person’s name if you’re not at a table)
2. Take your rock/ newspaper to your class’s storage location.
3. Wipe down your table top with a damp rag (not paper towels!)
4. Wash your hands and rinse out the sample cups you used.

1. Look at the actual sedimentary rocks you have, and consider your model. How is it similar to and different from the actual sedimentary rocks?
2. When your model was completed, did it appear how you expected? Describe what would be needed to make your model more similar to actual sedimentary rocks.
