CHEMISTRY FOR THE HEALTH SCIENCES (CHY107)Spring 2019

Meeting: Tuesday/Thursday 8:45-10 a.m. Place: Talbot Lecture Hall

Instructor: Dr. Timothy Searls

Office: Science Building 161

E-mail: timothy.searls@maine.edu and/or timsearls@hotmail.com

Office Hours: Tuesdays after class, or Wednesdays in Gorham noon in Bailey 215.

Please make an appointment if you want to be assured of a meeting. If these times

do not suit your schedule I will make every effort to find a time that works for us both.

Required: Essentials of General, Organic, and Biochemistry: An Integrated Approach, 2nd ed Denise

Guinn. 2014, W. H. Freeman. ISBN: 1-4292-2687-0.

Be aware that all textbook sales are now done online at:

https://usm.ecampus.com/

A simple scientific calculator (log functions and scientific notation are critical).

You must have access to a Blackboard account for CHY 107, as a great deal of supplemental

information will be posted there. Please let me know if you struggle to get onto Blackboard.

Optional: Student Study Guide and Solutions Manual, Rachel C. Lum. ISBN: 1-4292-2432-0.

There are endless sources of material on the internet, including a wealth of instructive videos on

YouTube and iTunesU, of which you can and should avail yourself.

Course Goals: Chemistry is part of our daily lives. It shapes the world around us, fuels our transport, influences our

climate, gives food its taste and smell, and is responsible for powering life itself. Chemistry 107 is an

introduction to general, organic, and biological chemistry. The ultimate objective of this course is to develop

an understanding of the chemical processes involved with living systems, particularly the human body. After

first examining fundamental chemical concepts including atomic composition, chemical bonding and chemical

forces, and organic chemistry, the goal of the course will be to develop how these concepts relate to biological

molecules such as nucleic acids, proteins, lipids, and carbohydrates.

Attendance will not be taken but is expected as a rule. It will not be possible to cover all of the material

presented in our textbook, and some topics will be discussed that are not covered in detail in the text. Further,

elements of chapters skipped at first may be incorporated into material covered later. In case of an absolutely

necessary absence the student is responsible for all work covered and announcements made.

The best way to learn Chemistry is to take time every day to practice the material by working problems,

reviewing notes, and by discussing it with your friends/classmates. Reading ahead and disciplined class

notes are the best preparation for your quizzes and homeworks, which will in turn be used to help you keep up

with the material and force you to review daily. If you find that you are getting behind or that you are having

trouble, please see me.

When you are in class you are expected to conduct yourself in an adult manner. Talking on cell phones,

ringing cell phones, or any text messaging is distracting not only to me, but also to your classmates. No

excuses. Turn them off. I’m serious.

Laptops can be used for note taking only if a medical explanation is provided in advance. Otherwise, no

laptops in class.

Grading:

9 Quizzes - 20% (after dropping the lowest) Two Examinations 20% each (40% total)

3 Homework assignments - 10% Final Examination 30% (cumulative)* *The Final Examination will represent 40% if it is a better result than your grades to that date, but will be only 30%

(and the rest of the grades 70%) if the result is below your grades to that date.

Quizzes and Homework:

Quizzes will be given almost every week that there isn’t an examination (see table below). The quizzes

begin at 8:45am during the first 10 - 15 minutes of class. The time will not be extended if you arrive late

to class. The quiz questions will often be based on readings assigned but not yet covered in lecture, as

well as the material most recently covered. Quizzes will also serve as a means of taking attendance. One

quiz can be dropped, so there are no make-up quizzes if you miss one. There is no make-up if you miss two,

and that second miss is a 0% for approximately 3% of your final grade. Take these quizzes seriously, as they

represent a meaningful percentage of your grade and are a strong predictor of where you stand in terms of

subject mastery.

Three homeworks will be assigned, which cannot be turned in late. I cannot stress this enough – they will

not be accepted late. An answer key will appear on Blackboard immediately following the class.
