Sensory Evaluations: There will be 11 chocolate tastings, 10 are counted in your grade. The
eleventh one will be counted as extra credit or replace one if you miss a class. You will not be
able to make up a missed tasting.
Tests: There will be 2 quizzes during the quarter, each worth 30 points. They can be multiple
choice and short answer. The final will be much the same format worth 100 points.
Group projects and evaluations: You will work in groups of 4 to create an idea for a chocolate
product and marketing of that product. At the end of the quarter your group will present the idea
(about 5 minutes) to the class. Each group will turn in a 1 page report and a package or label (20
pts) for your product the day that you present to the class The report should include: Product
manufacture (20 pts), Ingredients (15 pts), Marketing (20 pts), and a Company Mission
Statement (15 pts). Your presentation (10 pts) can focus on the marketing (like a commercial),
or you can present what the product is and how it is made. You may use PowerPoint for your
presentation, but it is not necessary. I expect all members of the group to contribute to the
project; however, you may choose one or two speakers to present if you wish. All members of a
group will receive the same grade for the project. After the presentation you will evaluate each
of your group members’ contributions to the project. Your points (out of 10) will be an average
of the points your group members award you.
