| This lesson was drawn from the second lesson in Science and Our
Food Supply: Investigating Food Safety from Farm to Table: Teacher's
Guide for Middle Level 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
curriculum that you will be using draws only from public health
lessons—not laboratory lessons—which are also available
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. |
