Name: ___________ HR: _____
What is a metamorphic rock? Talk this over with your neighbor and give me answer below.
Recipe for M.M.M.R.C. (enough for whole class):
1 and 1/2 cup of flour 1 cup of milk
1/2 teaspoon of salt 2 eggs
3 teaspoons of baking-powder
1 tablespoon of shortening
Pam non-stick spray
Add ins: raisins, nuts, coconut, marshmallows, choco chips
Mix the flour, salt, and baking-powder, add the milk gradually. Beat the eggs until
light and fluffy in another container and then add to the flour and milk mixture. Add the
shortening. Now stir in the raisins, nuts, coconut, marshmallows, and choco chips. Be sure
that both sides of the waffle-iron are hot and have been sprayed with Pam. Pour a small
amount of mixture into each waffle mold and close the lid. Open the lid and check to see
if the waffles are cooked. Repeat until all of the batter is gone.
1. Examine the metamorphic rock cake in front of you. How did the heat and
pressure of the waffle iron change each of your ingredients? Be specific!
2. How is this similar to how metamorphic rocks are formed in real life?
The Minerals in Sand
Purpose: Experiment to determine what minerals are found in salt.
|hand lens (magnifying glass)|
|Minerals Common Color & Shapes Chart|
Step 1: Spread a small sample of sand on a piece of graph paper.
Step 2: Observe the particles using the hand lens.
Step 3: Use the mineral color and shape chart to identify the particles you
List what you see here:
Step 4: Use a toothpick to spread out sand into one square so that the grains
are touching, but not on top of one another.
Step 5: Count the number of grains in the one square of graph paper.
Record that number here: _________________
Step 6: Now, use the toothpick to separate the different minerals in that one
List the minerals and the number of grains of each below:
Name of Mineral Number of Grains
Step 7: Display the data about each mineral in a bar graph below. Be sure to
include a title, labels for both sides of your graph, and a scale. Remember, the bars on a
graph do not touch.
Step 8: Based on your data, which is the most common mineral in your sand
Step 9: Create a line plot that shows the most common mineral for each group.
Record your data below in the frequency table.
