2 Laboratory (SCM) Scientific Measurements Expected Learning Outcomes Introduce laboratory glassware (pipet and buret) to practice technique .Compare and contrast accuracy and precision using experimental data Perform calculations with mixed operations, accurately reporting signifi- cant figures in each step of the answer Summarize experimental findings in appropriate visual representations (tables, charts) Introduction Suppose that you have a glass measuring cup. The volume of water present inside the measuring cup is indicated by lines marked on the outside of the glass. You read the initial volume using these markings, pour some of the water into a mixing bowl, and then read the final volume. With these two values you can calculate the volume of water that you transferred to the bowl. Would this measured volume of water that you transferred from the glass to the bowl then be equivalent to the actual amount of water transferred? This may sound like a silly question. You may think, "Of course it is the actual amount, I just measured it!" But what if the lines that are marked on the glass are not very accurate? What if you were sloppy when reading the volume, or when ring the water? It is quite possible the measured volume and the actual volume pour are different, and the amount of water added to the bowl is not what you initially thought it was. 15
