Final grades were posted to the Registrar at 11:15 am this morning (May 10, 2021). I will update your course scores in the next week. Please have a safe and wonderful summer. I have enjoyed working with you this semester. You will always be able to contact me via e-mail (, if you have questions or concerns.

Answers to Problem Sert 13 and 14 are now posted on your Personal Problem Set Page. Feedback for your answers to PS13 and PS14 is also updated.

From Dr. Iob, Director of Introductory Laboratories: Just a reminder that students can still check out tomorrow or any day next week (8:00 am to 5:00 pm). Last day for check out is Friday, May 7 (5:00 pm). If anyone contacts you, please tell them to come to PS 244 (or PS 243) during any of the specified dates and times. Otherwise, they will be charged $ 20 for not checking out plus additional fees for broken or missing items in their drawers.

BCE34 is now available on your Personal BCE Page. BCE34 is due before class on Friday, April 30, 2021. You may need a calculator for this BCE.

ACA36 is now available on your Personal ACA Page. ACA35 is due by 11:59 pm on Thursday, April 29, 2021.

I have posted a sample exam IV and a sample exam V on the Lecture Resources page at Wednesday, April 28th. Please note that I have added some questions to these sample exams so the time needed to complete these sample exams exceeds the time available to you during the final exam period. The exams you will be given on Thursday, May 6th will reflect a more reasonable expectation based on the time availaable.

PS14 is now available on your Personal Problem Set page. A subset of problems will be due on Tuesday, April 27, 2021 by 11:59 pm.

I have received official notification that we can have PS101 for Thursday, May 6, 2021 from 4pm to 5:50 pm for the CHEM 1515 Final Exam.

Average on EXAM III is 61. Awesome! I did end up changing a few exam scores. I have not updated the My Course Grades or the Grade Prediction pages yet.

Exam II average was 52. I have updated your Personal Grades page with more PS and Lab scores. If you have any questions or concerns I am happy to talk with you.

Exam I average was 57. This compares to Exam I averages of 63 (SP18), 58.6 (SP17) and 57 (SP16), so the average this semester is pretty consistent with past semesters. I will have more data after I get some lab scores from your TA. Once I have those I will be able to post scores on the My Course Grades link on your Personal Page. I will try to get that additional data ASAP. Still working on the BCE and ACA. Those should be posted soon.

I'm working on a new link to Lecture resources for class. You are welcome to make suggestions of what else I can place here. For now there is a link to an activity we will do in class on Friday to introduce intermolecular attractive forces (IMAF). Get it and bring to class.

The first thing you need to do to access materials for this class is to complete the Secret Identification (SID) form. Click on the SID#/Name link in the left frame and complete the form. You will receive an e-mail from Dr. Gelder indicating your SID has been accepted. Once you have entered an SID you can go to your Personal page. On your Personal Page check out the Assignment Page (what is happening in class), and get your personal Review Problem Set and Problem Set #1 from the Problem Set link.

Copies of the During Class Invention activities are located in the During Class Inventions and Computer Lab Activities Workbook .
