Summary
Student groups are challenged to create food packages for specific foods. They focus on three components in the design of their food packages; the packages must keep the food clean, protect or aid in the physical and chemical changes that can take place in the food, and present the food appealingly. They design their packaging to meet these requirements.Engineering Connection
An entire industry is devoted to packaging engineering and this industry is expanding as more and more products are created. Packaging engineers focus on the same components as students in this design challenge, which includes research, design, production, marketing and analysis.
Pre-Req Knowledge
Prior to this activity, students should have a basic understanding of the following:
- Physical properties of matter: mass, volume, melting point, boiling point and texture.
- Chemical properties of matter: combustibility, solubility, flammability.
- Physical changes: phase change, shape change.
- Chemical changes: oxidization, evolution of gas.
Learning Objectives
After this activity, students should be able to:
- Identify three key functions of a typical food package.
- Explain how each food package design works.
- Identify the chemical and physical changes different types of materials prevent or facilitate.
- Explain what a food packaging engineer does.

Introduction/Motivation
One specialty in engineering focuses on the food packaging industry. Food packaging engineers produce packages for all types of food that are both marketable and functional in selling the food.
Today, you have been contracted by the biggest food company, Food Kings, to create a package for one of their food products. However, you only get paid if you create a package that makes Food Kings lots of money. So prepare for your first task as a food package engineer!
Vocabulary/Definitions
boiling point: The temperature at which a substance changes from liquid to gas.
melting point: The temperature at which a substance changes from solid to liquid.
phase change: A transition between liquid and gas or liquid and solid.
solubility: The ability for a substance, the solute, to dissolve in a solvent.
Procedure
Background
Three important functions of food packages, as taught in the Food Packaging lesson, are:
- To keep the food clean.
- To protect the food product from unwanted physical and chemical changes (such as oxidation and destruction from insects) and to facilitate in desired physical changes (such as heating or cooling).
- To identify the product and provide sales appeal.
The challenge is for groups to strive to have their packages fulfill these three functions.
Students must first choose what types of materials they want to use to make their packages. They can research this through the food packaging materials worksheet as well as the Internet, based on how extensive the teacher want the research to be. The materials must correspond to the physical and chemical changes that are involved in the group's food.
In addition to choosing package materials, students must also choose the structural designs of their packages. Following are a number of structures and their characteristics and purposes:
- Cartons are rigid and provide support for fluid foods.
- Boxes are usually used as a secondary package to store foods that are sold in quantities larger than one, but are individually wrapped and give structure and support.
- Bags are flexible so can be stored easily.
- Cans hold liquids and carbonation well and can be stacked well.
- Bottles hold liquids and carbonation well and are resealable.
- Wrappers are light and do not take up too much space.
Before the Activity
A day or two before the activity:
- After going through the Food Packaging lesson, divide the class into groups of two or three students each.
- Assign each group a food to create a package for and have them brainstorm the design and types of materials they will need, with help from the Food Packaging Materials Worksheet.
- Give the students the Food Packaging Rubric so that they know what is expected of their package.
- Assign students to bring from home the materials that they plan to use.
The day of the activity:
- Gather materials that you are providing (glue, tape, etc.). Make sure you have enough for every group of two to share.
- Gather the foods that you assigned to the groups.
With the Students
- Give each student or group of students the food that was assigned to them along with the Food Packaging Rubric.
- Check to make sure each of the students/groups brought their own unique materials with them, and pass out the materials you are providing (tape, scissors, etc.)
- Give students 20 to 30 minutes to create their packages.
- Once completed, ask each group to share their package with the class as a 2-3 minute presentation to Food Kings on why their package works.
Worksheets and Attachments
Assessment
Pre-Activity Assessment
Food Analysis: Ask students to describe the physical properties of their foods and identify the chemical and physical changes that they need to pay attention to in the creation of their food packages.
Activity Embedded Assessment
Student Package Evaluations: Students use the attached Food Packaging Evaluation Worksheet to evaluate their food packages as well as the food packages of three other groups. Have groups each place their package on a desk with a brief description. Then, have all the students walk around individually to fill out their evaluations on different packages.
Post-Activity Assessment
Teacher Package Evaluations: Use the Food Packaging Rubric. to evaluate and grade the groups' designs.
Activity Extensions
Prior to this activity, have students create their own food that requires packaging. The creation can involve design, analysis of the nutritional content of the food, discussion of the genetic modification of foods, among other scientific aspects of food engineering.
Activity Scaling
- For lower grades, require fewer food package functions as design requirements. For example, students could focus more on shapes and aesthetic designs of the structure than the materials used to make it.
- For upper grades, require more food package functions be met. For example, students could engage a fourth function: for the package to be inexpensive, both in its materials and transportation. They could also look more thoroughly into the chemical changes and properties of the food and packaging materials. In some cases, they could test their designs.
