FABRICS AND FIBER KIT

Students perform four experiments analysing fabric and fibre types to learn to characterize them. First, students determine if each sample is animal,
vegetable, mineral, or synthetic in origin by subjecting fibres to a burn test and evaluating fibres for protein and for the presence of sulphur. Then,
students observe fibre samples to identify general microscopic characteristics and subject them to chemical solubility and stress and strain tests. After
learning techniques for proper collection of fibre evidence, students test three unknowns to determine their identity. Includes instructional manuals
and student worksheets. Required, but not included: microscopes, alcohol or Bunsen burners, matches, test tubes, 1-hole stopper, test tube clamp, and
distilled water. Designed for 24 students working in groups of four. Meets national standards for grade levels 10-12.
