Solubility tests are one method used to identify fiber content of fabric. Throughout this lesson, students will work in groups to learn about solubility tests and conduct a lab where they complete solubility tests to identify fibers. This lesson is designed to take one 50-minute class period. To grade this assignment, I like to use their justifications for why they think it was a certain fiber, instead of just assessing if they selected the right fiber for the sample. For this lab, you can either conduct the tests as a class and have all of the students observe one set of samples OR you can have groups of students conduct the experiments. It just depends on the size of your class and the volume of supplies, swatches, chemicals, and jars you have available.
