Jean Lab

In this lab we asked the question: What concentration of bleach is the best to fade color out of new denim material in 10 minutes without visible damage to the fabric. We found that the the best concentration of bleach was 50%, which provided the best fade of color without damaging the fabric. There was a significant color change in the 50% bleach, but didn't drain the color completely, and in addition did not damage the material very much. The 100% bleach drained the color completely while the 25% and 12.5% did not drain the color significantly. This data support our claim because it shows the perfect amount of bleach concentration in order to get the perfect color fade without damaging the denim.

While our hypothesis supported the data there could have been errors in our procedure. While we were bleaching all our denim squares at the same time, we could not take them all out at the same time, creating possible errors in the procedure. At the same time had some timer problems and we had to reconfigure to give us the right time to submerge the denim squares, therefore the squares may have been submerged a little to long or short. Due these errors, in future experiments I would recommend a more accurate timer and submerge less denim squares at a time, in order to get more accurate measurements.

This lab was done to demonstrate the scientific method and how we could use the scientific method in a real lab. From this lab I learned each step of the scientific method and what to do in each step in order to get an accurate and verifiable result, which helps me understand overall the concept of the scientific method. Based on my experience from this lab, I learned how to use and apply the components of the scientific method in an experiment to achieve accurate, verifiable results.
