{MLU: Minimizing length measurement uncertainty. For example in lab 3, you can use higher values of m so you measure larger distances with ruler so you have less relative uncertainty. How do you measure the thickness of a piece of paper using a ruler?}
{TH: When explaining the theory, try to be more clear about where the formulas come from and sketch a proof based on assumptions of the theory. For example, in lab 3, instead of saying that because light is acting wave-like we get the formula ... try to explain how one can drive that formula. Even if you don't know how to carry out the calculations, explain the physical interpretation you have in mind for the formula.}
{MAX: When there are both instrumental and random uncertainty for a measurement you must use the maximum of two as the uncertainty. If you think about it in few examples it will be clear why.}
{U: Units are missing or use units more often. I know sometimes it is too redundant to put units everywhere, but you need to use units more often. At least use them on the finishing point.}
{H: How did you get these values? The source of any numerical value you are reporting must be clear. Usually in our lab it is either based on a measurement or a calculation. Be more clear about where a value comes from.}
{AM: Any value that you measure must be reported in your lab report. For example, in lab 3, if you are measuring m=37 you must report the measured distance with ruler for m=37, then go on with calculations. Otherwise you cannot understand how much uncertainty you have for m=1 distance.}
{T: Use tables to report the measurements.}
{N: A page, figure, table, or ... missing numbers.}
{C: A figure, table, or ... is missing caption.}
{NU: No uncertainty given for a reported value.}
{LSF: The least significant figures for a value and its uncertainty must match. For example, you cannot only use 36 cm with instrumental uncertainty of 0.05 cm. It means at all your measurement you got exactly 36.00 or 45.00. That is really unlikely or you have a larger uncertainty that 0.05 cm.}
{TM: Too many significant figures used for the uncertainty. Use one or at most two. If you use one, you can easily estimate the uncertainty calculations in your head.}
{V: Vague and non-scientific use of language. Use more specific statements. For example, "human error" does not mean much. The question is to find where the error or source of uncertainty can be. Saying "human error" is almost as bad as saying "somewhere". As a rule of thumb, if you cannot imagine how one can test something that you are saying, try to think more.}
{NM: When the values which must match, doesn't, explore to see where you went wrong. Repeat the experiment. Ask your partner to repeat the experiment or calculations. This is the essential part of science. Usually you do mistakes first time experimenting or measuring. How you think and find the mistakes (like how to debug the code) is usually the most crucial part. So take advantage of your mistakes. A general heads up. In Physics 230 lab the experiments usually follow the theory with 10% error or less. If you get differences more than 10% usually means you are not using your setup properly or your prediction has problems. Some experiments like lab 3, if done correctly, has errors less than one percent!}
