Required Supplies: Bound laboratory notebook (the kind with duplicate pages); if not in bookstore, find online at: amazon.com laboratory notebook Laboratory safety goggles Calculator Graph Paper download free from http://pharm.kuleuven.be/pharbio/gpaper.htm) Laboratory Course Objectives: To supplement the course theory with hands-on experiments which demonstrate and reinforce the theory. To familiarize the student with the general laboratory procedures. To train the student in the art of scientific observation and objective data evaluation.

Instead, your lab grade is worth 23% of your Chem110 grade, and you must earn a minimum score of 70% in the laboratory to pass the class. If you attend all the labs, perform all of the experiments, turn in all of the assignments on time with correct calculations and correct answers to the questions, and follow safety regulations and university policies you can pass this laboratory course. It doesnt matter whether or not your experiment worked. Of course, it WILL work because you will plan ahead and follow directions. Laboratory grades will be based on 150 possible total points earned from the following categories: GRADING The grade in this course is assigned largely on the basis of points accumulated of a total of approximately 150 points in the following categories: Prelab 10% Lab report 80% Copy of that day's lab data from the notebook 10% SAFETY: The laboratory is a place to learn, but also a place of inherent danger. Proper preparation is imperative and required. Lack of preparation, including inappropriate attire or an incomplete/nonsensical pre-lab, may result in nonparticipation and a grade of zero. Approved eyewear must be worn at all times in the laboratory portion of the room whether you are performing an experiment or not. Food and drink is prohibited in the laboratory. Safety goggles are required. PRE-LAB. Before you walk in the lab. You must have the following 1) The title of the experiment, your name, laboratory section number, and date at the top of the page of your notebook. 2) Pre-lab report including experimental principle and a flow chart of the procedure of the experiment. 1) The principle of the experiment The principle of the experiment will include the reaction mechanism and the application of the experiment methods to study the biological questions. 2) The procedure of the experiment You can not copy directly from the lab manual. You have to write in your own words. NOTEBOOKS: An individual laboratory notebook is required to be kept by each student, and it must be with the student in the student work area at all times. All relevant calculations, measurements, and observations must be recorded. Errors should be noted as such, and retained. Notebooks must be kept up-to-the-minute during lab. ATTENDANCE: At the end of each lab period, students must turn in a copy of that day's lab data from their notebooks, with their name, the date, and any applicable data. Policy Regarding Late Lab Reports Lab reports are due at the beginning of your next scheduled lab session, unless otherwise instructed. Point deductions will be taken for late or incomplete reports. You must hand in PRINTED reports. All components of reports should be of high quality, as if for inclusion in a published paper. Grading template for CHE110 lab report Principle (2points) Mechanism of reactions (1 point) The purpose of doing this experiment (1 point) Procedure: (1 point) You need to draw a flow chart to get the full credit. Written paragraph wont get credit for the procedure part. Results: (5points) Evidence to support your results (4.0 points) Including everything you observed from your experiments, color change, precipitation (0.5point), pictures (0.5point), table (1 point) and graph (1 point) calculations (1 point). Final results for your unknown samples: (1 point) Discussion: (2points) What you have learned from this experiment? What can be improved for the experiment you performed? Any errors you made that affected the ultimate outcome of your results. The score for the lab report will be posted on the blackboard. Late lab report results will not be posted. Sample lab report will be provided online    9<>GUY[_`adfijk~ƽƟxmgch4B h#0Jjhn'U hn'hn'hn'jhn'Uh'XhhqhzhUSuhUSu5OJQJhD5OJQJh5V#hR5OJQJh0J5OJQJh5V#h%5OJQJh5V#h `5OJQJh[95OJQJh5V#h'~i5OJQJh5V#hz5OJQJ&(9=>MZ[OO $$Ifa$gdUSukd$$IflF%(@ 0d&    4 la $$Ifa$gdc@ $IfgdUSugd%gd% Z[j  e`[[gdp9gdvkd$$IflF%(@ 0d&    4 la $Ifgd'X $$Ifa$gdUSu      > ? @ L | ~   R   ' - . } ƿ{tm h!&h+ hp95\h!&hp95\hh0JjhU hhjhUhh'Xhp9hB h!&hp9 h!&h6BhvCJaJh9CJOJQJ^JaJhagCJOJQJ^JaJh9CJOJQJ^JaJhUSuh?%  S T g  Z [ y " | }  & F gdLu & F gdp9 & F gdp9 & F gd'X & F gdp9 & F gdp9 & F gdp9gdp9gd'X   pggg $Ifgdp9kdH$$IflF$'06    4 la $Ifgdp9     : ; < = L M N n o p q }  "#$MNoppqüüǼǼüǼǼǸüǼǼüǼǼüǼǼüDZDZüDZDZüǼh  hN/h\h+ h!&h\hgh\*h!&h\5CJ KH OJQJ\^JaJ h\CJOJQJ^JaJ h!&h\CJOJQJ^JaJD   ; < yppp $Ifgdp9kd$$IflF$'06    4 la< = N o p yppp $Ifgdp9kdn$$IflF$'06    4 lap q yppp $Ifgdp9kd$$IflF$'06    4 la wnnnn $Ifgdp9kd$$Ifl^F$'06    4 la$MNoypppp $Ifgdp9kd+$$IflF$'06    4 laopypppp $Ifgdp9kd$$IflF$'06    4 laypggg $Ifgd>{ $Ifgdp9kdQ$$IflF$'06    4 la HIpypggg $Ifgd>{ $Ifgdp9kd$$IflF$'06    4 lapqypg^ $Ifgd>{ $Ifgdl> $Ifgdp9kdw$$IflF$'06    4 laypg^^^ $Ifgd>{ $Ifgdl> $Ifgdp9kd $$IflF$'06    4 la>?@OPQxWX_`  !"WX\c夠|h^CJOJQJ^JaJ#h^h^5CJOJQJ^JaJhWFh\`hZhx hp95h"bhp95hp9hp95hp9hp95\hU< hp9CJhp95CJ\ hp95\hp9hgh}h\hl> h!&h\-?ypg^ $Ifgd>{ $Ifgdl> $Ifgdp9kd $$IflF$'06    4 la?@Qxypg^U^ $Ifgd} $Ifgd>{ $Ifgdl> $Ifgdp9kd0 $$IflF$'06    4 la`ytttoet\O ^`gdp9`gdp9 dgdp9gdp9gdp9kd $$IflF$'06    4 la %[\j:;E~`;gd3 dgdSX dgdSXgd gdhgdhgdY|gdIydgdIygd^gdp99:;BE~`hp;no}oaYQMhSXhSXhSX5hSXhtP5h>8CJOJQJ^JaJh BCJOJQJ^JaJh CJOJQJ^JaJhd6CCJOJQJ^JaJ#hKOhd6C5CJOJQJ^JaJ hh5h`[2hh5hhhmd(hYhIy hIy5\ h5\hIyCJOJQJ^JaJh^CJOJQJ^JaJhzCJOJQJ^JaJPQcsǺԺԺudWRJE h]@5hp-2h45 h.5h6Eh6EPJnH tH !h6Eh6EB*PJnH phtH hb5PJ\nH tH h1h6E5PJ\nH tH hbOJQJ^JhjOJQJ^JhbPJnHtHhh{PJnHtHh-whhPJnHtHhh5PJ\nHtH'h-whh5B*PJ\nHphtHh-whh5PJ\nHtHh6h31`avw+,,Xgd4gdbgdhaj+,BClmh'!h!u5 hkYh4hbh4OJQJ^J hyrh4h@h45h4hp-2h45Cmgd'!gd421h:p/ =!8"8#$% $$If!vh#v(#v#v@ :V l0d&5(55@ 4DyK changqingforever@yahoo.comyK Dmailto:changqingforever@yahoo.com$$If!vh#v(#v#v@ :V l0d&5(55@ 49DyK 1http://proton.csudh.edu/laboratory/labintro.htmlyK bhttp://proton.csudh.edu/laboratory/labintro.html$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l^065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554$$If!vh#v#v#v:V l065554s666666666vvvvvvvvv666666>6666666666666666666666666666666666666666666666666hH66666666666666666666666666666666666666666666666666666666666666666p62&6FVfv2(&6FVfv&6FVfv&6FVfv&6FVfv&6FVfv&6FVfv8XV~ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@ 0@PJ_HmH nH sH tH D`D NormalCJ_HaJmH nHsH tHZ@Z p9 Heading 1$<@&5CJ KH OJQJ\^JaJ R@R  Heading 2 d@&5CJ$OJQJ\^JaJ$VV O Heading 3$<@&5CJOJQJ\^JaJNN O Heading 5 <@&56CJ\]aJHH O Heading 6 <@&5CJ\aJDA D Default Paragraph FontVi@V  Table Normal :V 44 la (k (No List B^B z Normal (Web)dd[$\$4U@4 z Hyperlink >*phD>@D %Title$a$CJ$OJPJQJaJtH JJ@"J %Subtitle$a$CJ$OJPJQJaJtH H2H OHeader  !OJPJQJaJtH `CB` $$Body Text Indent  hx^h OJQJ^JjSj }>Z Table Grid7:V0ob vCourse Descriptiond1$7$8$H$1B*CJOJ PJQJ ^J _HaJmH phsH tH ^Oar^ vCourse Prerequisite d:B*CJaJph2B@2 p9 Body TextxPK![Content_Types].xmlN0EH-J@%ǎǢ|ș$زULTB l,3;rØJB+$G]7O٭VvnB`2ǃ,!"E3p#9GQd; H xuv 0F[,F᚜K sO'3w #vfSVbsؠyX p5veuw 1z@ l,i!b I jZ2|9L$Z15xl.(zm${d:\@'23œln$^-@^i?D&|#td!6lġB"&63yy@t!HjpU*yeXry3~{s:FXI O5Y[Y!}S˪.7bd|n]671. tn/w/+[t6}PsںsL.
