Scientifically oriented question – What is the estimated size of an oil molecule?
Evidence – The volume of the oil drop is 0.045mm^3 and the area of an oil drop is .196mm^2. The calculate thickness of the oil layer was .331mm.
Explanation- After finding the volume of an oil drop we calculated to find (0.065mm^3) the area of an oil drop (.196mm^2) our next step was to find the thickness of an oil drop (.331mm) personally finding the thickness was the hardest part of the whole lab. We the noticed all of theses measurements show the size of an oil molecule and I concluded that the size of an oil molecule is .331mm because that is the length.
connection- i remember you speaking to the class about a health situation with your father. As i remember correctly your father is on a blood thinner which has a form or rat poison in it. With having that deadly chemical in the medicine if they are even one decimal off the medicine will be ruined and your father will fall to serious medical conditions. also another connection is nanotechnology, this process is becoming to be used more and more in todays world. Medicine and sports are a big fields of nanotechnology.
communication- this always helps with hands on actvities. it gives you a better understanding of exactly whats going on in the class. also i can then help other students who are struggling with the lab.
Reflection – My group all calculated the same diameter because we added the same amount of oil and baby powder. Most of the other groups got different results because they did the lab a little different, but all the groups got very similar results. The formulas were all the same we just input different numbers. alot of the lab was some waiting for the oil to expand. eventually the oil expands to the whole diameter
