Providing Nutrients for your Body
Grades 6-9

Through building a life-size model, investigating enzymes, and examining actual specimens,
students visualize the process of digestion and become familiar with the organs involved in
transforming the food they eat into the energy their cells need to function. Students apply the
scientific method by determining the location in the digestive system where the digestion of
starch occurs. Students explore the role of detergents such as bile salts in the digestion of fats.

Biology of Food
Connecting Nutrition to Cell Biochemistry
Grades 6-9

Evaluating a healthy diet begins with an understanding of the biochemistry of the cell. The
structure of the major macromolecules and the role each play in the functioning of the cell is
outlined. Different food groups provide for the various needs of the cell as it grows and functions.
The roles of other nutrients such as vitamins and minerals are explored. A variety of lab activities
and model building are used to provide hands-on laboratory experiences to develop these concepts.
