Programs As we all know terrestrial invertebrates are valuable teaching tools. They are often used in public programs, classes, and as a main component of outreach programs. In addition to being the exoskeleton of many an educational program, many institutions provide fact sheets, teacher packets and curriculums using invertebrates as a main focus. In this section of the web site we would like to provide a resource for the sharing of information about programs and material that TITAG members present.
