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 different % of bleach can cause different damages to the jeans. The data shows 100% of bleach can remove all the color from the jean, but with only 12.5% of bleach there was hardly and color removed. scientist have done experiments involving bleaches effect on jeans, and they got a lot of different results depending on the % of bleach used. This data support our claim because if you do the same experiment then you will get the same result.
Our data was unexpected because we did not put in 3 cut outs of jeans at the same time. We also took some out to early. These errors will effect the result because timing is important in a lab. My recommendation is to read the instructions carefully and don't skip any of them. My second recommendation is that help and ask for help in your lab group.
This experiment was great i don't think it need improvement at all. This lab was important in understanding biological concepts because it helps the student in understanding the scientific method. This lad was done to demonstrate the effects of different solutions of bleach on cut outs of jeans.
from this lab I learned how the scientific method is properly used in a lab which helps me understand the concept of a good experiment procedure. Based on my experience from this lab I will be prepared to make an excellent experiment for my next lab.
