Jean Lab Conclusion
In this lab we asked the question, “What is the best bleach and water solution to bleach denim jeans?” We found that the 25% bleach solution worked the best. 100% was over bleached and purely yellow. While the 50% bleach solution was a lot less yellow but had a yellow color in the center of it. 25% was just right because the entirety of the squares was an equal and lighter color. The 12.5% was to weak and had no real effect on the jeans. 0% was just water so thing happened but we used this as a control..Our other pears used too much bleach and we know bleach drains color so they severely damaged the jeans. We thought that the more bleach we added, the lighter the jeans will be.
While our hypothesis was supported by our data, there could have been errors due to unreliable measurements and spills. We could improve this mistakes by being more careful and being more precise with our measurements. We did no really have any major mistakes so it did not really end up in any errors in our data.
This lab was done to show us the scientific method and conduct an experiment. From this lab I learned how to conduct a basic experiment that helped me with organizing tables and graphs in class. Based on this experience from this lab I can apply this to future classes of setting up graphs and tables as well as setting up simple experiments.
