notebooks, reports, graphing, exp 14, etc.

[Robert Zellmer]

I've received several questions concerning the notebooks, reports, etc.,
I decided to send something to everyone.

1)  There is no pre-lab for exp 14.  You MUST have the notebook prepared
     for lab this week.  There are some hints and changes to the manual 
(particularly
     for the mass of dichromate in part A).  Go to the following link 
and scroll
     down to exp 14.

2)  For those of you who haven't done it yet, you should have your 
notebook prepared.
     Take a look at the syllabus and the following link for an idea of 
what should be in there,

*Chem Lab Notebook Exercise - Guidelines for Lab Notebooks* 
<http://undergrad-ed.chemistry.ohio-state.edu/labnotebook/index.html>

     If you took 1210 you did the notebook exercise (found at the link 
above).  If you didn't
     take 1210 you want to look at the link.  It has some examples of 
good and bad notebooks.
     It should be rather obvious which is which.

     The next link shows an example I did for the first 2 steps from the 
lab manual for exp 12,

3)  Exp 14 is a FULL report.  All the reports are FULL reports

     If you want to know what a FULL report is look at the following two 
links,

*Chem Lab Report Exercise - Guidelines for Writing a Lab Report* 
<http://undergrad-ed.chemistry.ohio-state.edu/labreports/index.html>

*Lab Report Format - My Lab Report Example* 
<http://chemistry.osu.edu/%7Erzellmer/chem1210_sample_lab_report.pdf>

         The 2nd one is my example of what it should look like with what 
should go into
         each section.

     a) The procedure section in the report is simply a bibliographic 
reference unless
         you made any changes (which there will be in Part A for exp 14 
if using the
         potassium dichromate).  Any changes you make should go in this 
section below the
         bibliographic reference.  Otherwise we do NOT want any details 
of the
         procedure in the report.

4) Each week you must have your notebook prepared when you walk into lab.
     The TA will come around the lab in the first 10 minutes or so and 
check to
     see if you have the notebook prepared.  If not you can loose up to 
6 pts
     depending on what you have done.

     Any data you take in lab or anything you do related to the exp 
should go in
     the notebook.  Do NOT write in the manual or on another sheet of paper
     (even if you intend to copy it over to the notebook later).

     Record values to the correct sig. fig. and include units.  Use 
tables when possible.

     Always in PEN (report too).  If you make a mistake put a single 
line through it and
     write the correct data next to it.

     The TA will grade your notebook (worth 10 pts) and tell you how to 
improve it.


5) Exp 14 help

     a)  Go to the "Helpful Tidbits" link on my class web page (not 
Carmen) and you will
         find a link for exp 14 which should help with the lab itself 
and the report.  Read it
         before going to lab and then again before writing the report.

*Helpful Tidbits for 1220* 
<http://www.chemistry.ohio-state.edu/%7Erzellmer/chem1220/faq/faq_1220.htm>


     d)  Everyone should receive examples of good graphs in lab.  In 
case you don't,  you
         can find them at the link below.  The first graph doesn't take 
up the full page since
         I had to shrink it so I could write on it.  The 2nd graph shows 
an example when you
         have more than one set of data plotted.   You can bring the 
legend inside the graph
         area to allow the graph to spread out and occupy the whole 
page.  You don't need
         a legend when there's only one set of data plotted (as for 
graph 2 in exp 14).  You
         do NOT need grid lines for most of the graphs this semester.

         There's also a link you can use to help get you started with 
Excel if you've never
         used it before.  It's a simple example for a density graph. Go 
to the following link
         and you will find this, along with other useful links.

*Using MS Excel for Reports* 
<http://chemistry.osu.edu/%7Erzellmer/excel/excel.htm>

         Many of my examples use an older version of Excel (Excel 
2003).  I have a link
         explaining the major differences between it and the newer 
versions.  Again, click tabs,
         right-click, etc. and explore what it can do and where to find 
things.  Look at the
         links for my exp 14 example from Excel.  Also, look at the exp 
12 Excel example
         to see how to do certain things (calculations, more than one 
data set on a graph, etc.)


I hope this and my on-line help file address the majority of your 
questions.  If not ask.
