The document describes the process for making overnight cinnamon rolls. It begins by explaining the smells that wake someone up on a Sunday morning due to cinnamon rolls baking. It then lists the ingredients needed for the dough, filling, and icing. The ingredients are classified by physical state and type of mixture. The document discusses the physical and chemical changes that occur in making the rolls. These include whisking, kneading, shaping, rolling, and cooking. Laws of conservation of mass and energy apply as the ingredients combine without being created or destroyed. The seven step process to make the rolls is outlined.

OVERNIGHT CINNAMON ROLLS

2. Imagine that you are sleeping in bed on a Sunday morning. As you wake up,
you realize that a wonderful aroma has diffused into your room from the kitchen. As you
get closer to the kitchen, you realize that the scent you could smell were cinnamon
rolls. As you take the first bite of your Sunday morning treat; you probably do not realize
that many physical and chemical changes had to occur in order to result in your
delicious cinnamon roll. So today we will examine everything that must happen in order
for you to enjoy what you once thought was just a simple snack.

3. Our Ingredients
 Dough:
 4 large egg yolks, room temperature (liquid) (pure)
 1 large whole egg, room temperature (liquid) (heterogeneous mixture)
 2 ounces sugar, approximately 1/4 cup (solid) (pure)
 3 ounces unsalted butter, melted, approximately 6 tablespoons (liquid) (heterogeneous mixture)
 6 ounces buttermilk, room temperature (liquid) (pure)
 20 ounces all-purpose flour, approximately 4 cups, plus additional for dusting (solid) (homogeneous
mixture)
 1 package instant dry yeast, approximately 2 1/4 teaspoons (solid) (homogeneous mixture)
 1 1/4 teaspoons kosher salt (solid) (pure)
 Vegetable oil or cooking spray (liquid) (homogeneous mixture)
 Filling:
 8 ounces light brown sugar, approximately 1 cup packed (solid) (homogeneous mixture)
 1 tablespoon ground cinnamon (solid) (homogeneous mixture)
 Pinch salt (solid) (pure)
 3/4-ounce unsalted butter, melted, approximately 1 1/2 tablespoons (liquid) (homogeneous mixture)
 Icing:
 2 1/2 ounces cream cheese, softened, approximately 1/4 cup (solid) (homogeneous mixture)
 3 tablespoons milk (liquid) (pure)
 5 1/2 ounces powdered sugar, approximately 1 1/2 cups (solid) (pure)

4. Our ingredients
Acids Bases
 egg yolks  sugar
 eggs  all-purpose flour
 unsalted butter  Yeast
 buttermilk  Brown sugar
 Kosher salt  Ground cinnamon
 Cooking spray  Cream cheese
 Salt  Milk
 Powdered sugar

5. Physical and Chemical Changes
Physical Chemical
 Whisking the eggs.  Whisking all ingredients to create dough.
 Yeast making the dough rise.
 Kneading the dough.
 Shaping the dough.
 Rolling and cutting the cinnamon rolls.
 Cooking the rolls.

6. Using a Glass Container
pros cons
 It won’t melt unless under  It could crack, break, or
extreme pressure. shatter.
 It doesn’t stick to things
easily.

7. Conservation of mass
 Definition: Law of Conservation of Mass is a relation stating that in a
chemical reaction, the mass of the products equals the mass of the
reactants.
 We proved the law of conservation of mass because our ingredients
combined weighed the same as our finished product.

8. Energy Transfers/ conservation of Energy
 The first time energy was transferred was when the yeast made the dough rise.
 The second time energy was transferred was when the boiling water made the dough rise. Heat
was involved in the form of the boiling water.
 The third time energy was transferred was when the cinnamon rolls were put in the oven. Heat
was involved in the form of the oven.
 The law of conservation of energy states that energy cannot be created or destroyed.
 We did not create or destroy energy, we used already existing energy to carry out our cooking
experiment.

9. 1) Mix the dough 2) Shape the 3) Let the dough
dough rise
4) Store in the 5) Set over boiling
fridge overnight 6) Bake the cinnamon
water
rolls and frost.
