I. Abstract: The overall objective of the two labs was to allow students to become familiar with the microscope and use it to observe the different characteristics of the fibers acetate, nylon, and wool. The purpose of lab one was identify major characteristics of the previously mentioned fibers based on the longitudinal view. The purpose of lab two was to examine two fibers (nylon and wool) based on the cross-sectional view. This was accomplished by threading the sample fiber through a small piece of cork. The observations of both the longitudinal and cross-section view were recorded as well as sample drawing was recording as well. II. Introduction: Labs one and two are designed to help students get a better understanding of the microscope and how it functions. Lab one primarily focuses on using the microscope to view physical characteristics of the longitudinal view of a sample fiber. Lab two allows students to again use the microscope. This time it is used to view characteristics of the cross-sectional view of a sample fiber. III. Objectives: Lab One: The objective of laboratory one is to familiarize the student with the compound microscope and its use with ordinary light in viewing textile fibers. Lab Two: The objective of laboratory two is to help the student develop a technique for making fiber cross-sections by the cork method. IV. Materials and Equipment: Lab One: - Nikon Binocular Microscope - 10x objective piece - 40x objective piece - Seven rectangular glass slides - Seven cover slips for glass slides - Cotton fiber sample - Nylon fiber sample - Acetate fiber sample - Oil - Water - Cutting Block - Razor blade Lab Two: - Nikon Binocular Microscope

- Two pieces of Cork - Two rectangular glass slides - Wool fiber sample - Acetate fiber sample - Needle - Two pieces of thread - Cutting Block - Razor Blade V. Procedure: Lab One: 1. The microscope was turned on and inspected to make certain all the pieces were working properly. 2. The microscope was set to the 10X objective lens. 3. The materials were collected. 4. The first sample was prepared by placing a large portion of acetate fibers on the cutting block and using the razor blade to separate a small sample. 5.
