Since 1996 the Minnesota Microscopy Society (MMS) has had several different opportunities to use the “Microscopic Explorations” [1] handbook that has been developed by MSA in collaboration with the Lawrence Hall of Science [2] as part of their Great Explorations in Math and Science (GEMS) series. Initially we used a beta-test version of the manual and worked with several different schools in the St. Paul's school district. Since then we have broadened the range of our outreach, and have interacted with different school districts, as well as local museums and other youth and community organizations - including church youth groups, scout groups and local governments. One of the strengths of the manual is that it can be used in many ways, and is adaptable to the particular learning situation available. These opportunities can span the range from essentially uncontrolled interactibns with the general public, with its large age range and ability spectrum, to the very carefully structured setting of an ongoing, single-age class program.
