Food Packaging

(Complete Item Description)

Abstract:: This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or aid in the physical and chemical changes that can take place in a food, and identify a food appealingly. Then, in the associated activity, the students will have the opportunity to become packaging engineers by designing and building their own food package for a particular type of food.

"Kitchen Chemistry, Spring 2009"

(Complete Item Description)

Abstract:: " This seminar is designed to be an experimental and hands-on approach to applied chemistry (as seen in cooking). Cooking may be the oldest and most widespread application of chemistry and recipes may be the oldest practical result of chemical research. We shall do some cooking experiments to illustrate some chemical principles, including extraction, denaturation, and phase changes."

Online Science-athon: The Chocolate Melt

(Complete Item Description)

Abstract:: The Online Science-athon offers elementary and middle-grade students opportunities to discover the science in their daily lives. Presented as challenges, the Science-athon asks students to investigate their world in ways that are engaging and fun, easy for teachers to incorporate into their teaching, and instructive. Students doing the Chocolate Melt decide on a container-tin can, cardboard box, plastic bucket, paper bag, or similar object-to use as a solar cooker. Then they consider how to melt a refrigerated standard-size milk chocolate chip that has been placed on the end of a toothpick inside the cooker in as short a time as possible. This includes figuring out how to reshape the container so that the heat from the sun is concentrated on the chocolate chip, deciding what colors and textures to use for lining inside surfaces and insulating the cooker, examining where to put the chocolate chip, and identifying how to point the cooker at the sun. Reviewing scientific information helps students improve the effectiveness of their cooker designs and make predictions about the ones they think will cook the most rapidly. On Chocolate Melting Day, students collect and record data to share with other students doing the challenge.

Package those Foods!

(Complete Item Description)

Abstract:: This activity provides students with the opportunity to create a food package for a specific food. The students have three components to focus on in the design of their food package. The package will have to keep the food clean, protect or aid in the physical and chemical changes that can take place in the food, and identify the food appealingly.
