Course Description:

From consumer products to space age technologies, chemistry affects our daily lives. In this course, students will learn the structure of matter and how it behaves under various conditions in order to better understand the chemical world. Designed for students with little or no chemistry background, this course can stand alone or be followed by CHEM& 161 (formerly CHEM

142) or CHEM& 131 (formerly CHEM 220). Laboratory activities extend lecture concepts and introduce the student to the experimental process. (LAB)

Course Overview:

This course covers selected sections from chapters 1-10, 12-15 and 17 in Tro.

Students will be introduced to a variety of topics in general chemistry through a combination of lectures, labs, and group activities. Homework assignments and exams will be given in order to reinforce the concepts presented in class. A group project on a topic relating the course material to either human or environmental health will give the students an opportunity to explore more deeply how chemistry is part of their everyday lives.

The laboratory is a mandatory part of the course. Each lab requires a significant amount of preparation before you enter the laboratory. Always be prepared for lab.

Safety First!

Many chemicals in the lab are hazardous, so handle all chemicals carefully and dispose of all waste properly.

Be aware of yourself and those around you at all times (pay attention!). The experiments and report sheets (except for the chemical resources lab) are contained in the CHEM& 121 Lab Manual. The requirements for lab reports are also in the Lab Manual. Proper lab attire includes closed shoes, and coverage below the knees. Wear your goggles at all times! The lab work and post-lab calculations represent a significant amount of work outside of lab, and will be due one week after the lab work is completed. Pre-labs will be due


each lab begins. Lab reports will generally be due the

Wednesday following each experiment (see daily schedule). The lowest lab score will be dropped.

No make-up labs

will be possible.


must be worn whenever anyone in the lab is working with chemicals or glassware.

No food or drinks are allowed in the lab.

Although you will share data, and are encouraged to discuss any aspects of the lab with your classmates, you are expected to write and turn in your own individual work for your reports.

Special Notes Regarding Lab:


If you arrive to lab late

(after the safety and procedures lecture) you will not be allowed to participate in the lab. You may stay as an observer, take down data and write up the report for a maximum of 65% credit for the lab report.

*You must pass the lab portion of the class with at least 50% of the total points available (after dropping your lowest lab score) in order to receive credit for the LAB portion of the class.


You will be required to submit the signature sheet (provided in the lab packet) at the second lab meeting (first wet lab). (If under 18 your parent or guardian must sign).


Homework will be assigned using WebAssign. The best way to use your time is to work the problems through on paper and then submit the entire assignment on WebAssign all at once. You will receive feedback immediately, and you can re-work the problems that had errors. Homework will be graded for accuracy, significant figures, and units, with partial credit given for each.

Working through problems is the best way to understand chemistry. The more problems you do, the more likely you are to succeed in this course; working additional problems beyond those assigned is highly recommended. For that reason, extra assignments will be added to WebAssign for a reduced amount of “extra” credit.

Working with a study group is a great way to break through tough material, and to gain a deeper understanding of concepts. Just be sure your work is actually your own!


Group Activities:

There will be three group activities, one for each Unit, which will be completed in class. The activities are due at the end of the class period in which they are completed (see daily schedule). Although you will work on these in groups, each student must hand in their own paper to get credit. These activities are a chance to apply the material covered in the reading, lectures, worksheets, prepared problems and homework in collaboration with your peers.


During the first week of class you will formulate a set of personal goals for the class and design a plan to meet these goals. Several weeks into the course you will have the opportunity to reassess your goals and revise your plan as needed, as well as to assess the structure/elements of the class. At the end of the course you will reflect on your success in meeting your goals and on the effectiveness of your plan.


Students will form small groups and each group will choose a topic on which to prepare a poster to be presented at a poster session towards the end of the quarter. The project will involve relating one or more concepts from the class to human and/or environmental health. Each group of 3-4 students will prepare one poster, one summary sheet and one poster presentation outline. Each student will also write a reflection on the group process. More information on the project will be given out in a separate handout.


There will be three exams (55 minutes) and a comprehensive final.


Although attendance is not directly a part of your grade, poor attendance will likely result in a lower grade due to missed exams, prepared problems or labs, late assignments and gaps in your understanding of the course material. If you miss a class, it is

your responsibility

to obtain the lecture notes and any other handouts from the web site, or from a classmate,

not from the instructor


Late Assignments:

All assignments (except for activities) are due at the beginning of class on the due date. In general, no late work will be accepted. Labs will be accepted one day late, at 50% penalty.

WebAssign allows students to request extensions online. Extensions will be granted to the entire class, or heavily penalized.

Note: If you expect to miss class, you may submit assignments to me early

(hard copy or by email) to get full credit.


For a re-grade on an exam or assignment you should write a brief explanation of why you should receive more credit, attach it to the exam or assignment and give it to me no later than one week after the assignment/exam was handed back to you. If a simple arithmetic error was made in adding your score, see me for an immediate correction.

Attitude and Class Participation:

Please show respect towards myself, and your fellow classmates, by listening when others are speaking, by participating and allowing others to participate in group activities, and by keeping all criticism constructive. Every question is a good question, so please ask questions in class. Chances are other have the same question but are afraid to ask. When I ask questions of the class, try to answer even if you might be wrong. Often the wrong answers are the best lecture tools.

Please turn off all cell-phones, pagers or other electronic communication devices during class.

See me if you have a legitimate need to have yours on. Please refrain from packing up until I dismiss class.

How to Succeed:

Read ahead of lecture, and do homework every day. Keep up with the material, come to class, hand in all assignments, study early for exams, and above all get help when you need it.

Read the chapter before lecture and after. Be prepared for lab.

Get help early

. Don’t wait until the day before the exam to clear up your questions. Chemistry should be interesting and exciting as well as challenging, so have fun!

Class materials:

You should bring your calculator to both lecture and lab. If possible, bring your book to class. Always bring your lab sheets, goggles and a pen to lab.

Flu Information for Students

Cascadia is taking steps to prevent the spread of seasonal and H1N1 (Swine) flu on campus. Please read the important information below and help Cascadia prevent the spread of flu.

Make sure that Cascadia has your current contact information, just in case we need to reach you. Update your contact information by going to Kodiak Corner or online at Under the Network Access and

Personal Information heading, select the link to the Student Address Information.

If you are ill, stay home and notify your instructor by phone or email. Continue to turn in your homework and assignments by email or as directed by your instructor. Return to Cascadia


when you are symptom-free without the use of medications.

You are encouraged to be vaccinated this fall against both seasonal and H1N1 (Swine) flu.

Vaccination is the best protection against contracting flu.

Your instructors each have plans to continue teaching in the unlikely situation that the physical buildings on campus would need to be closed. Your instructors will provide details about how this will work for your particular classes.

Preventing the Spread of Germs

Health officials recommend the following precautions:

Cover your nose and mouth with a tissue when you cough or sneeze. If you don’t have a tissue, cough or sneeze into your elbow, not your hands.

Wash your hands with soap and water frequently, especially after you cough or sneeze.

Alcohol-based hand cleaners are also effective.

Try to avoid close contact with people who are ill.

Avoid touching your eyes, nose, and mouth.

If you get sick, stay home and limit contact with others to avoid infecting them.

Symptoms of H1N1 (Swine) flu are similar to the symptoms of seasonal flu that happens each year. These may include fever, cough, and sore throat, as well as fatigue, body aches, headache, chills, runny nose, vomiting, and diarrhea.
