Remove the fiber from the glass microscope slide, remount the fiber on a quartz microscope slide, and cover it with a quartz cover slip using glycerin as the mounting medium. Synthetic fibers (man made) tend to be smooth and uniform, and some may have long extrusion lines on the outer layer. in this investigation, you will identify the fiber on your shirt by doing a microscopic analysis and perform a burn analysis on known fibers. 4.1 the basic activities involved in a fiber examination include case assessment, the search for and collection of fibers, preparation of the sample(s) for analysis, analysis using appropriate techniques, and evaluation of results. Group work (15 20 minutes): students will use microscopes to analyze the different fiber samples. see the premade student lab report as a possible example of student work.
