From site:  The K-12 web-site was constructed to assist science and biology teachers in the K through 12 grades interested in developing interactive laboratories and demonstrations that teach the basic principles of science and the scientific method.

K-12 Teacher’s Guide to Lessons and Laboratories
A description of interesting and tested experiments and lessons that demonstrate scientific principles in relation to the microbes that exist in our everyday environment using plant pathology. Each exercise includes background information, grade level recommendations, learning objectives, study questions and answers, and a list of materials and supplies (with suppliers) that will be needed.
