    1. Tf

      I dont see an average Tf value, which would be good to have. You should probably explain how exactly to rearrange eq 1 to get the slope in your methods. You have a good discussion about what the error and precision mean, but it can be expanded on a little bit. Otherwise its a solid results and discussion section

    2. presentation

      The calculations section is a little hard to follow, and there is an instance of a present tense word in your methods. (paragraph 1, is). Other than that, it needs a little bit of shortening/taking out redundant words. But it is pretty solid.

    3. explained

      i is not 1 for weak electrolytes, because they still dissociate just not fully. We cant calculate i for weak electrolytes yet. Your introduction is pretty solid, but it needs a bit of succinctness. There are a couple types that need to be fixed too, such as "complexly"

    1. easy to follow

      Good introdduction section, except it is a little scattered and it might be better off with some shortening/ making it more concise.

    2. depression

      This report is pretty strong, but can use a little bit of work. Mainly just shortening up sentences to be more concise. Another thing to work on is to explain which points of data were important on the labquest. Otherwise good job.

    3. Freezing

      This report does a good job of explaining the results of the experiment, and thoroughly introduces what exactly a colligative property is. Good job.

    4. freezingpoint depression

      I would re-word this so that you use the words "freezing point depression" less. Maybe say "Tf represents the change in temperature from the initial freezing point"

    1. measured

      There is little background information on the subject. No equations or summary. A thermometer measure temperature changes, not a calorimeter.

    1. First subtractthe initial volume from the final volume, take the answer and input it into equation 1 asthe volume or β€œv” in this case, the result given is the density of the rod

      Not in passive voice.

    1. od by the finalvolume.

      This is incorrect, as the students should have used the difference between the final volume and the initial volume, to get the volume of the rod.
