Cookbook Recipe
Dr. B's Big Soft Ginger Cookies
Submitted by: Better Homes & Gardens
CHEMISTRY INFORMATION: The pure substances are baking soda (NaHCO3), salt (NaCl), and sugar (C12H22O11). The ingredients that are homogeneous mixtures are all-purpose flour, ground ginger, ground cinnamon, ground cloves, butter, and molasses. The fully mixed batter is also a homogeneous mixture. The heterogeneous mixtures are the egg, the batter before it is mixed, and the cookies after they are finished baking. The butter warming up after it is taken out of the refrigerator, and the dough being formed into balls are both physical changes. The puffing up of the cookies and the change in aroma as they bake both indicate that chemical changes are taking place. NUTRITION INFORMATION PER COOKIE: 142 calories, 2 g protein, 21 g carbohydrates, 6 g fat, 11 mg cholesterol, 118 mg sodium, 56 mg potassium

Cookbook Recipe
Noah S’s Magic Cookie Bars ( Modified From All Recipes.com Eagle Brand)
CHEMISTRY INFORMATION: My recipe does not have any pure substances. But, the water that you use to clean up after you bake the cookies is a pure substance (H2O). A homogenous mixture in this recipe could be the sweetened condensed milk. Another one could be the nonstick spray that coats the pan. The last one could be the half a cup of melted butter. These are all homogeneous mixtures because, you can’t see the different substances in the ingredients and objects. There are also some heterogenous mixtures too. One of these could be the cookie bar when it’s all done. Another one could be when you layer the chocolate chips and the coconut and they don’t mix. The last one is when the milk and graham cracker crumbs are added. All of these things can easily be distinguished. One physical change that occurs is when it is all cooled and you cut it into the different shapes. Another one could be when you firmly push all the ingredients together with the fork. One way that you can tell a chemical change is occurring is when the bar turns from a bright white to a different color when you take it out of the oven. Another way you can tell is when you watch it bake the, ingredients are rising. Submitted by: "Noah S"

Cookbook Recipe
Sara’s Great Big Soft Sugar Cookies! Modified from Cooks.com
This is the chemistry information from my recipe. The pure substances that are in Sara’s Great Big Soft Sugar Cookies recipe are, baking soda (NaHCO3), and sugar (C12H22011). The ingredients that are homogeneous mixtures are butter, almond extract, and all purpose flour. The ingredients that are heterogeneous mixtures are the egg before it is beaten together, the batter before everything is mixed together, and the cookies after they are fully cooked. Two physical changes that occurred are one, when you mix the egg altogether, and its color changes that is a physical change, and two, when you melt the butter, and it turns into a liquid, that is a physical change too! Two clues that there are chemical changes that occur when making the cookies is one, having the cookies rise in the oven from the baking soda, and two, the smell of the cookies changing while they are cooking! Submitted by: "Sara S"

Cookbook Recipe
CJ S.’s Apple Crisp (modified from Apple Oatmeal Crisp - allrecipes.com)
This is the chemistry information for my recipe. The pure substance is table sugar (C12H22O11). The homogeneous mixtures are all-purpose flour, brown sugar, ground cinnamon, and the melted butter. The heterogeneous mixtures are the apples, the rolled oats, and the finished product. The butter warming up in the microwave, and the apples being chopped up into little pieces are both physical changes. The browning of the apple crisp and the change in aroma as it bakes are both clues of chemical changes. Submitted by: "CJ S."

Cookbook Recipe
Alexandra’s Chocolate Gooey Butter Cookies (Modified from Paula Dean)
Recipe Backstory: CHEMISTRY INFORMATION: In my recipe I do not have any pure substances, but an example of one would be sugar (C12H22O11). Some homogeneous mixtures in my recipe would be the 1 brick of cream- cheese, the 1 stick of butter, the 1 tablespoon of vanilla extract, the 1 box of moist chocolate cake mix, and the confectioners’ sugar. These would be homogeneous mixtures because I can’t see all of the different things that make up these ingredients; they all look the same throughout. The heterogeneous mixtures in my recipe would be the one egg because I can see all of the different things that make up the egg, the batter before it is mixed, and the cookies after they are done baking. The 1 stick of butter being warmed up and the dough being formed into ball are both physical changes. One sign of a chemical change in my recipe would be when the cookies start to smell when they are being cooked in the oven. Another sign of a chemical change would be when the when the cookies are puffing up and getting bigger because of the baking soda. Submitted by: "Alexandra M."

Cookbook Recipe
Zachary H’s delicious Apple Pecan Cobbler (modified from Christine Cahill)
CHEMISTRY INFORMATION: The pure substances are sugar (C12H22O11), and salt (NaCl).

Krystian W’s Fried Dough, modified from the experts of Food.com
The pure substances in the Fried Dough are Salt (NaCl), and Sugar (C12H22O11). The ingredients that are Homogeneous mixtures are Flour, Milk, and Baking Powder. The Heterogenous mixture in this food is the Shortening. At the point when you have a nice thick mixture in the bowl, you can see its a heterogeneous mixture because it still has some clumps of dough. Its fine if you have it like that, but if you want it crushed up more, you can do that. The dough being formed and the dough getting a different texture when it is rolled on a lightly floured surface are both Physical Changes. There are two signs of chemical changes when you’re making the fried dough. The first one is the dough turning a golden brown color when you fry it. The second chemical change is the nice odor formed after the golden brown dough is made and taken out of the pot. It has that nice, bread/cake smell. Submitted by: "Krystian W"

Faith G's Blondies (modified from www.foodnetwork.com
Recipe Backstory: CHEMISTRY INFORMATION: The pure substances are baking soda (NaHCO3),salt (NaCI),granulated sugar (C12H22011) Ingredients that are homogeneous mixtures are pure vanilla extract, all-purpose flour, brown sugar, semisweet chocolate chips, and butter. Heterogeneous mixtures are the egg and walnuts. My two physical changes are when you mix the dry ingredients with the wet ingredients, and when you flatten the batter in the pan changing the shape. One sign of a chemical change is after the bars have been cooked they turn brown before burning. When they inflate it will produce carbon dioxide,making the holes in the bars. This is a sign of a chemical change. Submitted by: "Faith G."

Max’s Brownie Recipe Modified Version from NESTLE® TOLL HOUSE COCOA MIX
Pure substances are sugar(C12H22O11), water(H2O), and salt(NaCI). Homogeneous mixtures are flour, butter, cocoa mix, baking powder, and vanilla extract. Heterogeneous mixtures are nuts and eggs. When you crack the eggs open this action causes a physical change because its physical shape is changing. When you mix the flour in with batter this causes a physical change because you are mixing it into a different shape and texture. When you bake the batter in the oven this creates more gases which is a sign of a chemical change. Another chemical change is during the cooking process when the brownies turn slightly a different color. Submitted by: "Max L."
