8. Sun Mon Tue Wed Thu Fri Sat Image credit: Microsoft Clip Art Grades (discussions and projects) will be posted within 5 days of their due date (the Sunday of the following unit). For example, Unit 1 grades (discussion, seminar and self-assessment) will be available by Sunday of Unit 2. Sun Mon Tue Wed Thu Fri Sat Grading

9. Gradebook and Dropbox Image credit: Microsoft Clip Art Distribution of Points: Discussions 360 points (9 units @40 points each), Mini- projects (Units 2, 5, 8; @98-105 points), Self-Assessments (9 units @5 points each ), Seminars (9 units @6 points), Exams (Units 4 and 9; @120 points each)

10. Grading, cont’d. Image credit: Microsoft Clip Art Remember … I do NOT give grades. You EARN your grades. A student earns points by meeting the key criteria listed in the grading rubrics found in your course syllabus. It is a good idea to review the grading rubrics before you begin each assignment so that you know exactly what I will be looking for. Please review the Course Calendar in your syllabus for assignments and their due dates.

11. Late policies All unit assignments are due Tuesday by 11:59 PM EST of the unit assigned. Late assignments will be marked down one letter grade for each unit the assignment is late. Assignments submitted more than three units late will not be accepted. Please let me know as soon as possible if you think you may not be able to complete your assignments on time – the sooner you contact me, the better. You do not have to describe any personal issues in detail but please at least let me know what the problem is. Active communication is the key to overcoming any hurdles you may encounter during the term. It is your responsibility to inform your instructor (ahead of time, whenever possible) of extenuating circumstances that might prevent you from completing work by the assigned deadline. Please note that evaluation of extenuating circumstances is at the discretion of the instructor and documentation may be required for verification of the extenuating circumstance. Examples of extenuating circumstances may include but are not limited to: personal/family member hospitalization, death in the family, weather/environmental evacuation due to fire/hurricane, or active military assignment. General computer-related or internet connectivity issues are not considered extenuating circumstances.

12. Communicating with your instructor 1.Ogubanova@kaplan.eduOgubanova@kaplan.edu All emails will be answered within 24 hours on weekdays or 48 hours on weekends and holidays. Please resend your email if you do not hear from me within this timeframe. When you email me, please write your section number in the subject line (e.g., SC300-27), this will allow me to get back to you quicker. 2.AIM – ogubanova, at any time that you see me on. If you would like to set up an office hour (on AIM), please let me know so that we can make arrangements. 3. In Seminar, you can send me a private message by clicking on my name in the list on the left-hand side of the seminar screen. Student-to-student private messaging will be disabled, as seminars are not chat rooms. If you want to talk to another student about something, please email him or her later.

13. Unit 1 Assignments Introduce Yourself Please take this opportunity to introduce yourself to you professor and an classmates in this unit and to learn a little about each other. Video Lectures Please watch the Thinkwell video lectures for this week. Notes and transcripts for the lectures can be found in Doc Sharing. Reading Chapters 1 & 2 in Chemistry Made Simple. Supplemental workbooks have also been posted in Doc Sharing. Discussion – Chemistry in Your Life Seminar – The Four Elements: Earth, Wind, Fire and Air Self-Assessment (Quiz) Please also be sure to work through this week’s Self-Assessment.

15. Earth, Fire, Water, Air Ancient philosophy about the elements Empedocles, about 500 BC – The Tetrasomia, or Doctrine of the Four Elements – Earth, Fire, Water and Air. Aristotle taught that these four comprised everything in the universe. Democritus thought differently and taught that everything contained atoms (from the Greek word atomos, meaning “cannot be divided.”) Our understanding of the Universe has come a long way since then! We now know that the universe consists of more than a hundred elements made of subatomic particles that are held together by fundamental forces.

31. KU Science Center Tour – 10:45 PM ET Please open the link in a new browser window: http://khe2.adobeconnect.com/kusc_tour/ Use the Guest option when signing in (no password required. It takes a minute or two sometimes to connect to the platform depending upon connection speed. Once you get into the adobe room, it is best to close any other programs since it requires a lot of memory to run without delays. You do not need to come back to this seminar after the tour. See you all next week!
