The SI Microscopy labs are designed to be used with or without a physical microscope. Lens paper and slides will ONLY be included in your kit if your instructor has opted for you to use a physical microscope. If you do not receive lens paper or slides and they are not on the materials list for your course, your instructor has selected to use our digital microscope, the Virtual Microscope. The V-scope can be accessed using the link in any microscope-based lesson.
