Dyes, Fibers, and Paper: A Botany Lab Exercise for Non-Biology Majors
Egan, Todd P.; Meekins, J. Forrest; Maluso, Diane
Bioscene: Journal of College Biology Teaching, v30 n1 p15-18 Mar 2004
This laboratory exercise affords students a hands-on experience learning about traditional dyes, fiber strength, and paper making. It is economical, simple to prepare, provides satisfactory results, and is student friendly. Dyes were extracted from plant leaves, stems, roots, and fruits. Hard-boiled eggs were place in the dyes for 15 minutes to determine what color each dye would produce. Colors of the eggs differed from the colors of the dye solutions. Fibers were procured from different materials (cotton, jute, hemp, etc.). Filaments were removed from the twine and a stress test was used to determine the strength:weight for each fiber type. Twine from each fiber type was used to make rope using the rope maker from the Boy Scout's Pioneering merit badge pamphlet (1993). Paper was made from recycled fibers suspended in water. A homemade deckle was used to collect and press the fibers to make a sheet of paper. Students found the exercise interesting and stimulating. (Contains 1 table.)
