The JC policy is that class runs as scheduled unless school is cancelled, so unless JC officially cancels school we will have the exam tomorrow at 11am, no exceptions.
If class is cancelled we will have the test on Tuesday at 9:00 am and then run the talks between Tuesday lab period (10:30-12:30) and Thursday class time (11:00-12:30).
We will be doing Lab 8 – Thin Layer Chromatography for lab tomorrow. Lab6/7 are being redesigned and parts will be used for a handout next week that will be assigned for practice.
The grades for CEM131 are posted for Post Exam 2. There was a formatting error in the one I showed the morning class which had some grades screwed up. I have corrected the error, but please double check against your handed back work.
Wow, looks like a good chunk of people read the exam from last term in CEM131 and used that as study. Here is some advice, I change a significant chunk of questions between terms… And I knew, due to a question a student asked, that the old test was being used… So I made sure a changed almost every question.
Yes we have a quiz on Wednesday. Since it is on a new unit I would think vocabulary is important.
I talked about this in class on both Thursday last week and the Thursday the week before, but I am still getting questions about this on my email. The first exam for BIO220 is on Thursday the 28th. This is one day later than the syllabus due to the day lost to Convocation. It will cover Chapters 1, 2, and 4… Plus the material on Nature of science in the PowerPoint slides.
Class will be on time today (9/21/17), but morning office hours are canceled due to delay at rheumatology.
In BIO220 we assume that you have had a functional grasp of Chemistry, hence the phrase “strong background in biology is recommended” (which requires chemistry) is in the catalog description. While chemistry isn’t the point of this course, it is inevitably interwoven in any course that touches on molecular biology (Units 2-4 in this class). The Pathways system is not supposed to let you take BIO220 right out of the gate, but it seems to miss that more often than I would like. However, I only have about a lecture and a half to get through basic chemistry review, so below are a couple of videos to help those who may be struggling.
Basic Atomic Structure (Khan Academy)
Basic Bonding (Khan Academy, you can skip metallic bonding)
Basic Biomolecules (Amoeba Sisters)
Properties of Water (Amoeba Sisters)
Here are the Syllabuses for the CEM131 Sections. The only change is the loss of Week 3 lab with the shift of the other labs down one week (eliminating lab 5) due to Convocation. Since Convocation (the change) is on Tuesday and your class is M/W, it does not affect lecture/exam schedule.
