You may already be familiar with Microslide Lesson Sets from other classroom work. Microslide Lesson Sets have been used by over 187,000,000 students so there's a good chance they may be somewhere in your school. These Lesson Sets are made up of strips of 35mm photomicrographs of tissues, and organisms seen through microscopes. Each strip is accompanied by an explanatory text folder and, usually a Student Worksheet. The 'film strip' is viewed with a special program called the Micro-Slide-Viewer.
