Science Shorts: Spoilage Science

Journal ArticleDigital resources are stored online in your NSTA Library.

Whether it’s fresh or processed, all food eventually spoils. Methods such as freezing, canning, and the use of preservatives lengthen the lifespan of foods, and we—and the modern food industry—rely on these methods to maintain our food supply. This month’s Science Shorts explores the concepts of food spoilage and prevention.

To understand food preservation and food preservatives one has to understand what happens as food spoil. The introduction to this activity is a good one for food spoilable and what is happening. The activity however deals with preserving food and is a good simple one for making observations. However, with this said I think children should first observe spoilage and that part is missing from this activity.
