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. To purchase a CD-Rom version of K-12 online materials and the illustrated glossary, click here.

Illustrated Glossary

Resource Guide to Materials Related to Plant Path-Ways to Science
An annotated list of publications, videos, books, supplies and other links and resources for students and teachers interested in additional information.

Mentors
A list of mailing and electronic addresses of volunteer mentors who are willing to provide some assistance or suggestions to teachers regarding the materials, plans, classroom visits or simply to help and advise teachers needing additional information or clarification. The mentors are identified by the type of information or assistance they are able to offer.

Bulletin Board. 
Forum. This monitored section of the bulletin board provides an opportunity for teachers who have used the information and who have conducted some of the experiments described in the Teachers Guide to post a summary of the experience or to ask questions related to items within any part of the K-12 website.
Post-It. This monitored section of the bulletin board provides an opportunity for K-12 teachers to inform teachers and site managers of experiences with the lessons they have tried, or of previously unlisted events, workshops, or resource materials.
