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

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

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:

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.

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?

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.
