Encourages students to think like scientists as they develop meaningful understandings about science concepts related to the traditional methods of food preservation. The unit focuses on the preservation of fish, but could easily be expanded to other foods. Students gain insight through direct experience with the process of science and through interaction as members of a cultural community.

At the heart of the unit, based on the Alaska State Standards, are these understandings:

1. Traditional food preparation methods can be examined and explained through scientific investigations
2. Science is a process of solving real problems
3. The importance of traditional foods is more than how food is prepared and eaten; it is also reflected in social protocol and interactions
