Questions about the start of the term:
I already have an InterChemNet (ICN) code/account and/or a notebook from another semester. Do I have to purchase a new ICN access code and notebook?
Yes. ICN access is granted on a per course/semester basis. In general, if you register for the lab course, you need to obtain a new ICN code and a notebook. An exception is if you took an incomplete in lab and will be completing the lab course in the next semester. See Robert Kirk, laboratory manager (229 Aubert Hall)
When do general chemistry labs start?
The General Chemistry lab courses (CHY 123 and 124) start the first week of classes. During the first week, you will attend a mandatory safety training and lab orientation meeting scheduled at the time of your lab session.
I get an error when trying to activate my ICN account, what do I do?
If you are having issues with your ICN barcode, please contact firstname.lastname@example.org
Are there recitations during the first week of classes?
Often yes. Please check with your instructor .
Questions about retaking, dropping, or changing a class or laboratory section:
I am retaking the class. Do I need to retake the lab?
Students who have taken the general chemistry laboratory in the last four years and have gotten a grade of C or better do not need to retake the lab if they retake the class.
I plan on dropping class, can I stay in lab?
No, for safety reasons we do not allow students who withdraw from class to continue in lab. However, we can offer to facilitate your completion of the lab when you retake the general chemistry class. If you have received six or more lab grades of at least 90% you can request to be excused from these experiments when you take the course again. We will need to see all your graded lab reports and your lab notebook. Contact the lab manager, Robert (B0b) Kirk, at the beginning of the semester you retake the class and lab and he will be able to help you.
I want to change my lab section, what do I do?
It’s possible to change your lab section, since we offer a number of lab sections throughout the week. However, movement between sections depends on available space. Start by visiting the chemistry main office (154 Aubert Hall) and asking Jean DesRochers if there are any openings in the section you’d like to move to. Robert (Bob) Kirk, the laboratory manager (229 Aubert Hall), can also sometimes help in changing sections, but only after you’ve first checked with the chemistry main office.
Questions about laboratory course safety:
Can I wear contact lenses in lab?
No, because it is not safe. In lab, there can be very low concentrations of chemical gases that normally are drawn out of the room by fans. At these low concentrations, the gases are safe. However, if you wear contact lenses, since they are (usually) gas permeable, the moist interface between the contact lens and your eye can become an area that concentrates the chemicals – leading to an unsafe condition. There are also additional reasons. For example, even though you wear protective goggles – there is always a chance that a chemical solvent can get into your eyes. If this happens when you are wearing contact lenses, they may prevent you from being able to safely wash the chemical out of your eyes. Hard contact lenses also have safety issues. Thus, our rule is based on safety considerations. Please wear your glasses in lab – it is really for your protection.
Where can I find out additional information about lab safety?
Visit the General Chemistry Website at http://umaine.edu/general-chemistry/ and follow the link to Policies. You will find there a link to a pdf file that has additional information concerning safety.
Questions about missing labs, make-up labs, and arriving late:
What do I do if I need to leave early or arrive late for a lab? Can I just get data from my lab partner to finish my lab?
No. You are expected to complete the lab experiments yourself and be there the entire time. Even if you are asked to pair up and be part of a group, you are required to participate during the entire lab. Many times in lab, things don’t go as planned or are not as straight forward as you first thought. As a rule of thumb, if you miss more than 15 minutes of lab, you should plan to make up the lab at another time. See the FAQ section concerning making up a labs.
I missed or will miss a lab. How can I make it up?
1. Consult the schedule of times that laboratory meetings are held. Contact the laboratory instructor of this section and ask if there is space in the section for you to make up a lab. Tell them which lab experiment you wish to complete.
2. Complete the pre-lab assignment and carefully read the procedure of the lab.
3. Arrive early to the room (at least ten minutes) where you have scheduled a make-up session and check in with the instructor before lab starts. If the materials you need to make up the lab are not present, you will need to go collect them from Bob Kirk (room 229). If you do not ensure the materials are in the room before the start of lab, you may not be able to make up the lab during this session.
4. At the end of lab, obtain the laboratory instructor’s signature on your lab notes.
5. DO NOT hand in laboratory notes or laboratory reports to this instructor. Get them to your own laboratory instructor as soon as possible.
Be advised that you may not be able to hand in a laboratory report that is more than two weeks late. See the UMaine General Chemistry Laboratory Manual for more information about policies on late work.
Can I always make-up a lab?
No. (a) Due to the large number of students enrolled in lab classes, a request to make up a lab during any given lab period is not guaranteed and is at the discretion of Bob Kirk and the lab instructor with whom you will make up your missed lab. (b) If you attempt to make up a lab two or more weeks after it has been given, you need to initiate a discussion with Bob Kirk well in advance of the lab period you will make up the lab. This is because you may have to help prep the lab (make up solutions or find equipment).
Questions about InterChemNet (ICN):
I am not able to download a procedure that I need for lab. How can I fix this?
You may not have completed the online post-test questions at the end of the previous lab. Go back and check. When you have completed these questions, the next lab will become available. If the questions are complete or there are no questions, e-mail your instructor and indicate which lab you need (WELL AHEAD OF TIME). They may be able to e-mail you a copy. If the problem persists contact Robert (Bob) Kirk.
I’m having trouble viewing the film clips. What should I do?
This could be due to a broken link or your security settings on your computer may be set too high. If you are using Windows XP, before reporting a possible broken link, first try the following: go to Control Panel, SecurityCenter, Internet Options, Security, Default Levels, move the slider from High to Medium. Then try the movie again.
Questions about doing well in general chemistry:
I seem to learn differently than other people. Can I learn more about this?
You can get feedback on your learning style by taking a simple learning styles quiz. The quiz is found on various sites on the internet. Here is a site that was active on September 15, 2011: Learning Styles.
How can I get off to a great start in chemistry?
Attend class, keep up with assignments, and find other students you can ask questions and study with. If Peer Led Teaming Learning is offered, participate. If electronic homework is used, use it to strengthen your understanding of course materials. If you have questions about class or lab, contact your instructors.
I think I am going to need extra help. What should I do?
Make sure to collect the contact information provided by your professor and laboratory course instructor at the beginning of the semester. Be sure to find out where their offices are and what times they are available for providing extra help to students. They also may be able to direct you to students that provide private or group tutoring.
