I need my students to learn that… The history of chocolate is related to the development of civilization. Using simple chocolate recipes you can identify fractions, mixed numbers, and improper fractions and solve the basic operations . The Cocoa Supply chain includes everybody who plays a part in producing chocolate ( from a cocoa bean to a chocolate bar). Chocolate plays an important role in the world’s economy. Chocolate exits in different states of matter. Chocolate has many versatile uses. (medical, cosmetic, culinary, currency, confectionery ) Chocolate has health benefits.

Task # 2: Social Study Connected Creation of a new route for Avianca Airlines to visit the countries involved in the Cocoa Supply Chain. Task # 3: Science Connected Conduct an experiment to create a new chocolate bar for Wonka’s Company and demonstrate that chocolate exists in more than one state of matter. Task # 4: Technology Connected Creation of a wiki to persuade aliens to utilize chocolates in their planet. Math Chocoholics Task Card #1 BACKGROUND Math is in every kitchen, on every recipe card. The mathematics of cooking often goes unnoticed, but in reality, there is a large quantity of math skills involved in cooking and baking. Most recipes give guidelines as to how much a single batch will produce. But what if you want more? It seems too time consuming to mix up another batch. What if the recipe makes only one dozen cupcakes and you need three dozen? Clearly, three dozen is three times more than 1 dozen, so you can multiply all the ingredients by three to make a larger batch. It is also important to understand how to multiply fractions. If the cupcake recipe calls for ¾ cup of milk and you want to triple it, you need to know that. So, you will need 2 and 1/4 cups of milk to make three dozen cupcakes. This knowledge of fractions is also helpful when we need to make our batch smaller. CHALLENGE The Ghirardelli Chocolate Company, one of the oldest chocolate companies in the United States, has hired you to adapt their brownies recipe, according to the number of costumers visiting their Chocolate shops. You must apply your fraction knowledge to half, double, triple, and quadruple the recipe and turn all resulting improper fractions into mixed numbers. Classic Chocolate Brownies Recipe Batch: 16 brownies Ingredients: 1/ cup Ghirardelli Semi-Sweet Chocolate Chips 2 4 ounces Ghirardelli Semi-Sweet Chocolate Baking Bar 1/ cup (1 stick) unsalted butter, cut into pieces 2 1 cup firmly packed light or dark brown sugar 1 teaspoon pure vanilla extract 2 large eggs 3/ cup plus 2 tablespoons all-purpose flour 4 1/ teaspoon baking powder 4 3/ teaspoon salt 8 http://www.ghirardelli.com/recipes-tips/recipes/classicchocolate-brownies Geo-Chocolovers Task Card #2 BACKGROUND The cocoa supply chain includes everybody who plays a part in producing chocolate. Even simplified, this is a long list, from framers, cocoa processors, chocolate manufacturer, exporters, and local buyers. To achieve meaningful change, all of these groups must collaborate effectively and prioritize farmer benefit at origin over competitive advantage. Many countries of the world play an important role in this chain, while governments and companies are helping to strengthen the supply chain as a whole and to move towards a more sustainable cocoa economy. Visit this link for more information: http://www.mars.com/global/brands/cocoasustainability/supply-chain.aspx#showall CHALLENGE Avianca Airlines has hired you to create a new route that stops in the countries involved in the Cocoa Supply Chain. To follow the journey from a cocoa bean to a chocolate bar, you must locate on a map the main countries in charge of the following processes: 1.Growing the cocoa and processing it, 2.Manufacturing the chocolate and exporting it 3.Consuming it. You must create a color key to label each process listed above. Bio-Chocoaddicts Task Card #3 BACKGROUND: Everything on Earth is made up of microscopic particles (molecules, ions, or atoms), and the speed and density of these particles determine which state of matter and object is. The properties of the three elements are very easily defined and identified. Solid A solid is anything that holds a particular size and shape. An apple, a block of wood, and a penny are all solids. The only way they can change their shape is by force (for instance, if you bite the apple with your teeth or chop the block of wood with an ax). Liquid A liquid is anything that has size or volume, but does not have a shape. Liquids must be contained in a cup, bottle, or receptacle in order to have a shape. Milk, water, and juice are liquids. Gas Gases are hard to identify because they have no color or shape. Take a deep breath and feel your lungs get bigger. Your lungs are filling up with air, and air is a combination of many gases. It has no shape or size. CHALLENGE Willy Wonka wants you to help him create a new chocolate flavor. In order to do this the following processes must be followed: 1. Melt a chocolate bar. 2. Mix the liquid with different ingredients of your choice such as fruits, peanuts, marshmallow pieces, etc). 3. Place the mixture in chocolate molds. 4. Store it in the freezer. Visit the following link: http://www.bbc.co.uk/schools/scienceclips/ages/8_9/solid_liquids.shtml After conducting the experiment, answer the following questions: 1. What happens to the chocolate when you heat it? 2. How does the chocolate move as a liquid? 3. After you store the chocolate in the freezer, what do you notice about the chocolate when you test it? 4. Once a solid has turned to a liquid, can it be changed back to a solid again? 5. Which moves more liquid chocolate or solid chocolate? Techno-Chocomaniacs Task Card #4 BACKGROUND: Chocolate has many versatile uses that fall outside of the traditional culinary boundaries. In the past it has been used as a medicine and currency; now it is sometimes molded into large chocolate sculptures or melted into chocolate fountains, or even used in cosmetics and extreme examples of fashion wear. Stories on the Health Benefits of consuming Cocoa Products have increasingly made the news. Research studies has found out the following benefits of consuming (dark) chocolate: • eating chocolate does not trigger migraine headaches, • eating chocolate reduces the risk of heart disease and cancer. • eating chocolate does not give someone acne or other skin eruptions, • eating chocolate boosts one's appetite, but does not cause weight gain, • eating moderate amounts of chocolate makes one live almost a year longer, • eating chocolate releases endorphins in the brain, which act as pain-relievers, • the sugar in chocolate may have a calming and pain relieving effect. CHALLENGE The world has been visited by aliens looking for new sources of energy. NASA has hired you to develop a wiki persuading aliens to utilize chocolate. You must let the aliens know where chocolate comes from, its main uses, and what are the benefits of consuming it. If you fail… planet Earth is in great danger.
