Recitation and Lab Announcements

Week 13: April 3, 2017
What to turn in: The Alum report (pages 9 & 10) and abstract. Click here for the abstract rubric.

What you need to do to prepare for lab: Read the “Solutions and Titrations Lab”. This lab has two components, but you will only do the part for “Week #1”. To prepare for the prelab quiz, read the lab, answer the prelab questions, and look at the ChemPages modules on the following topics:

 

Week 12: March 27, 2017
What to turn in: "Molecular Shapes” report pages 5-8.

How to prepare for lab: Read Experiment 7 (Alum from Waste Aluminum Cans) and answer the prelab questions. Please review the ChemPages module on "Filtration, Vacuum" since you will be using similar equipment in this week's lab (you may skip the part on "Connecting the trap" since you will not be using a trap, but you will be using a water aspirator, so pay particular attention to those parts). Also, you will need to bring in a piece of aluminum can that has been cleaned/scraped of the outer plastic/paint coating. Using a piece of sand paper, steel wool, or a brillo pad works well. See the lab manual for details (step 1 of the procedure). Doing this procedure BEFORE lab will save you quite a bit of time.... Also, heads up! You’ll be writing an abstract for this experiment. Your instructor will give you the rubric, but here it is again, in case you lose it.

Week 11: March 20, 2017
NOTE THE LAB MIDTERM EXAM WILL BE IN RECITATION THIS WEEK!!! HERE IS THE EXAM TOPIC LIST HANDED OUT IN LAB

What to turn in: The Periodic Properties Lab (pages 9-12) AND two graphs assigned in lab. Be sure to COMMENT on the periodic trends that you see and credit the source (book or website) of your information.
How to prepare for lab: Read the Molecular Shapes lab and answer the prelab questions. No ChemPages, but there will be a prelab quiz.

Week 10: March 13, 2017
What to turn in:
“Determination of the Atomic Mass of Magnesium” pages 9-10, spreadsheet, and formula page.
How to prepare for lab: Read “Periodic Properties”, answer the prelab questions, and read the appendix of the lab manual and view the ChemPages module on the “Gas Burner” (see the "Safety 2" in the Additional Topics of ChemPages). Expect a prelab quiz. NOTE ABOUT THE LAB MIDTERM EXAM! While it was originally scheduled for March 27, it will be moved up a week to March 20th. An exam topic list was given in lab this week (and posted here).

Week 9: March 6, 2017
Spring Break! No labs this week.

Week 8: February 27, 2017
What to turn in: "Hydrogen Emission" experiment (pages 9-12) AND the calibration curve (Excel plot--this needs to look nice with a title, labeled axes, equation of the line, R2 value, removal of white space, etc.)) AND the energy level diagram (use the graph paper in the lab manual).

How to prepare for lab: Read the experiment “Determination of the Atomic Mass of Magnesium”, answer the prelab questions, and view the ChemPages on the “Gas Burner” (all sections and “Safety 2” in the Additional Topics) and “Balance” (all sections, but pay particular attention to the Additional Topics on “Weighing Hot Objects”). An additional page on the Bunsen Burner is on the next to last page of the lab manual—please read this before recitation. Note that you will perform two analyses of the metal, so be sure you overlap the procedures (i.e., while the first sample is cooling, the second one is being heated). Also, since there is copious use of a Bunsen burner in this lab, be sure to tie back long hair.

 

Week 7: February 20, 2017
What you need to do to prepare for lab:
Read Experiment 4 (Hydrogen Emission), answer the prelab questions, and view the ChemPages modules on "The Spectroscope, Hand-Held" and "Vernier Scale" (inside the "Scales" module). Expect a prelab quiz!

What to turn in:
The Physical Properties Lab report (pages 5-7), spreadsheet, formula page, and graph (be sure there is a proper title, axes are labeled, white space on graph has been removed, etc.).

Week 6: February 13, 2017
What to turn in:
The PC lab sheets and post lab questions (pages 7 to 9) with the chromatogram stapled to page 8. There is no spreadsheet for this lab, however there *IS* an abstract that you must write. Be sure to read two documents in the appendix: Microsoft Word features for writing in chemistry and Considerations for writing abstracts; the latter document tells you what should be in an abstract as well as what shouldn’t be in an abstract, gives examples, and mentions some of the more important writing rules in science. A rubric specific to the Paper Chromatography experiment is here—be sure to look at this before you turn in your assignment!

What you need to do to prepare for lab: Read Experiment 3 (Physical Properties), answer the prelab questions, and, if you haven't already viewed the ChemPages modules on

do so before lab. There is no prelab quiz this week.

 

Week 5: February 6, 2017
What to turn in:
The BLT report (pages 15-17), spreadsheet, AND formula page. Be sure to use formulas for all calculated values on the spreadsheet. Keep track of those sig figs, too, this lab is heavily weighted for sig figs.

How to prepare for lab: Read the Paper Chromatography experiment, answer the prelab questions, and view the ChemPages module for:

You will have a prelab quiz that could include safety information, too.

 

NEW TO SPRING 2017!! This semester you are required to complete the online “Laboratory Safety Course for Undergraduates” at www.flinnprep.com. BEFORE lab on Jan 30. Sign up and make a student account, then enter the “Student Linking Code” (SLC) vlv9h for your account to be activated (this will cost you nothing!! DO NOT PAY FOR THE COURSE!). Your lab instructor will give you another five digit SLC to link your account to his/her “classroom”; enter that one, too. Watch all of the videos and answer the quiz at the bottom of the page. You must score at least an 80% to certify your safety training.

Week 4: January 30, 2017
BE SURE YOU HAVE LONG PANTS, SHOES THAT COVER YOUR ENTIRE FOOT, A LONG FORM LAB COAT, AND GOGGLES FOR LAB THIS WEEK!! See lab manual for acceptable clothing items.
Turn in:
Safety lab (pages 7 & 8) and the spreadsheet assignment (computed version, formula page, and the graph--have these printed BEFORE your lab meets).

Prepare for lab: Complete the Flinn Safety Prep course by watching videos and taking the 19-question quiz at the end. In lab, BE READY for a prelab quiz on the Basic Labs Technique (BLT) experiment. Note that safety information will be found on most/all of the prelab quizzes, so be sure to stay current with that information. Read the Basic Lab Techniques (BLT) experiment, answer the prelab questions, and view the ChemPages for:

Remember that the link for ChemPages is available through SpartanGreenSky; log onto the ChemistryBiology virtual desktop—the ChemPages modules are on the left side in the middle of the screen. If you are having trouble accessing the ChemistryBiology virtual desktop, contact the IT helpdesk (Helpdesk@uscupstate.edu or call 503-5257).

 

Week 3: January 23, 2017
Finally! Recitation and lab will meet! Recitation is the classroom hour that precedes the 21/4 hour laboratory meeting. Bring your lab manual, calculator (CASIO fx-260Solar), wear long pants and close-toed shoes, and bring a way to save data from a computer (USB drive is the easiest). You can prepare by reading the safety lab. You will need a full length lab coat AND goggles for next week’s lab, but if you have it at the first lab meeting, you can store it in your locked drawer.

Week 2: January 16, 2017
No classes on MLK Day. Instead, make it a day of service. Register for local service projects with the United Way of the Piedmont.

Week 1: January 9, 2017
For this first week, there are no labs or recitations, but do get the lab manual from the bookstore (available on Monday Jan 9th), along with safety goggles (not glasses), a full length lab coat (lab coats may be available from the Chemistry Club for a much discounted price, details soon), the course calculator (CASIO fx-260solar), and it is recommended that you have some type of device to save files from a computer (e.g., USB drive).
For the first lab you will need to be able to log onto the computers in the Smith computer lab--so check with IT before lab if you have a problem with accessing the on-campus computers.
