teacher note

This lesson was drawn from the third module in Science and Our Food Supply: Investigating Food Safety from Farm to Table: Teacher's Guide for High School Science Classroom (National Science Teacher's Association, (703)243-7100).

This innovative and supplemental curriculum introduces students to the fundamentals of microbiology while at the same time imparting important public health information.

The curricula found in Science Our Food Supply were developed in cooperation with the U.S. Food and Drug Administration (FDA). The curricula that you will be using includes two laboratory lessons and three public health lessons. In different formats, these lessons are in Science and Our Food Supply. The lessons have all been tested by an experienced team of middle level teachers and meet National Science Education Standards.
