In this lab, we asked the question: What concentration of bleach is best to fade the color out of new denim material in 10 minutes without visible damage to the fabric? We found that no matter what concentration of bleach we used, there was no significant visible damage to the fabric, however the color did change. The rankings of color removal were significantly higher for the larger concentration of bleach than those with a lower concentration. But, unlike what we expected, there was no visible damage to any of the fabric. Bleach is already known to break down substances and make them a lighter color. This data supports our claim because the jeans with a larger concentration of bleach got lighter.
Our data was unexpected because of some errors we made. We accidentally kept the wrong time by a few seconds for the soaking time and drying time. We also didn't label correctly all the time and got confused as to which jeans were with which concentration of bleach. We also accidentally soaked one batch in bleach instead of water for a few seconds until we realized. This all probably affected the outcome of the lab. In future experiments, we will read the directions carefully and be organized with our labeling.
This lab was done to demonstrate the scientific method, how it works, and how to use it effectively. From this lab I learned to make a hypothesis based on known information, which helps me understand the concept of the scientific method. Based on my experience from this lab, I now know how to solve problems using the scientific method and can apply this to even more problems.
