Chemistry 101 Grading

 

Homework:................. Homework will be given for each chapter.  The test and final questions will come from these questions.  The assignments will NOT be collected but you are expected to have completed them.  I will know if you have completed the homework when I grade your tests.  Please note that the test questions will come from the homework.

 

Attendance:................. This will be taken at the beginning of each class meeting.  Attendance will be utilized when determining the final grade for borderline students and will count for 5% of your final grade.  Please note that the material will come very fast and missing a class will be detrimental to your understanding of the material and your final grade in the class.

You will not be automatically dropped if you do not attend.  If you decide to not complete the class it is your responsibility to drop.

 

Tests:.......................... The questions will primarily come from the homework questions from the book.  The tests will count for 40% of your final grade. 

 

Final:.......................... The final questions will primarily be taken from the tests.  The final will be cumulative and cover all tests.  The final will count for 15% of your final grade.    Failure to take the final exam will result in an automatic fail in the course.

 

Grading:...................... The grade you will earn will be based on the following scale and a semi-modified scale.

 

A         90% - 100%

B         80% -   89%

C         65% -   79%

D         55% -   64%

F           0% -   54%

 

I guarantee that you will receive at least the above grade if not higher due to modifications of the curve to fit the class performance.

 

Grade Breakdown:....... The final grade is based upon your grades in both the laboratory and lecture.

Hints for a successful Chemistry 101

 

Chemistry 101 is a demanding course.  It demands much time due to the sheer volume of work you must process for laboratory and lecture.  It demands much effort to understand and learn the many new ideas presented in the course.  You can have a successful, even interesting semester if you practice some of the following hints.

 

Work on chemistry every day.  Do just two or three problems or read just a few section of the current chapter.  You will often need to try a problem several times before you fully understand it.  You will need to read the text several times before you really know the material.

 

YOU CANNOT CRAM CHEMISTRY! DON’T TRY!

 

Try to stay ahead of the lecture.  Skim the anticipated lecture topic the day before the class.  Then you know what is in the book and need not take so many notes.  You then can LISTEN AND THINK DURING THE LECTURE.  CAREFULLY READ THE EXAMPLES AND SOLVED PROBLEMS IN THE TEXT.  Cover the author’s solution and work them yourself immediately after reading the text.  Do the suggested end of chapter problems.  You cannot solve text problems efficiently without LOTS OF PRACTICE.  Reread the appropriate section in the text and review your notes.  If you cannot solve a suggested problem or don’t understand it, look for a similar problem among the text’s examples.  Think about it for several days.  ASK FOR HELP to get started from your instructor or fellow student.

 

Look for CONNECTIONS between the current lecture topic and previous topics or your prior knowledge of chemistry or physics.  Look for practical applications of what you are learning.

 

Finally, DON’T PANIC!  Take the course one step at a time and let your understanding grow.  You will be amazed at how much of the materials you have assimilated by the end of the semester.

Calculations

Uncertainty and Significant Figures

 

The Least Accurate Number (LAN) determines the number of digits to which the answer is expressed.

 

Addition and Subtraction

 

1.      The LAN is the number with the least number of digits following the decimal point.

2.      The answer (sum or difference) can have no more digits following the decimal point than the LAN.

 

         Example:

                        What is the total mass of a mixture made by mixing the following substances?

 

                                         212             g water (LAN)

                                              1.8         g salt

                                              1.88       g sugar

                                         ____________________

                                         215.68       g (incorrect)

                                         216             g (correct)

 

Multiplication and Division

 

1.         The LAN is the number with the least number of significant figures.

2.         The answer (product or quotient) can have no more significant figures than the LAN.

 

            Example:

Calculate the volume of a rectangular solid that has a length of 4.16 cm, a width of 2.2 cm, and a height of 2.00 cm.

 

            Volume = Length x Width x Height

 

            Volume = (4.16cm) (2.2cm) (2.00cm)

                                              LAN

 

            Volume = 18.304 cm3 (incorrect)

 

            Volume = 18 cm3 (correct)

FINAL LABORATORY EXAM (13, 14, 15, 16, 17, 18)**

(2)        Indicates that for this experiment students will work in pairs.

*           Indicates that for this experiment an unknown will be assigned.

**          You may use your laboratory notebook (comp book) during this exam


Laboratory Notebooks

(Note: Your Notebooks will be graded using this criterion.)

General Directions

 

1.         Always write in ink.  (NO PENCIL!)

2.         Write only on the right-hand side of the page.  (The left-hand side of the page should be used for calculations, notes, etc…)

3.         Number all right –hand pages in the upper right-hand corner.

4.         Just beneath the page number indicate the date on which the laboratory work was done.  When the experiment work is done on two different dates, indicate the second date (right –hand margin) at the point where the second day’s work begins.

5.         The laboratory notebook is an original permanent record.  This means several things:

            a          You must write down all data directly (in ink) in the lab notebook.  There will be a grade penalty when a student disregards this rule.  (The rule means:  no writing in pencil; no writing on the lab report sheet, on pieces of paper, etc…)

            b.         There will be no erasures, no “white out”, and no missing pages.  One thin line may be used to cross out offending material.  (Later you may discover that you need this information and this way you can retrieve it!)

            c.         Never Remove a Page from the Laboratory Notebook.  (At some point this practice could have legal implications; patent fights are won and lost on the legitimacy of lab notebooks.)  If you do make a dreadful error and would like to remove a page, do the following: draw a diagonal line across the entire page.

            d.         Holes and spots from chemical spills are legitimate artifacts; do not worry about them.

 

Format for the Laboratory Notebook

 

1.         Leave one or two pages at the beginning for a Table of Contents.  On this, list each experiment title (as you perform the experiment) and in a column at the right of the page, give the page number where the experiment write-up starts.

 

2.         Begin each experiment on a fresh right-hand page.  Each write-up includes:

            a.         Title:  At the top of the page give the title of the experiment.

            b.         Page number and date:  At the top right-hand of each page.

            c.         Purpose:  Describe what you are doing and why.  Describe what information you are attempting to gain by doing this experiment.

            d.         Procedure: Give references to the location of the procedure in the text and any deviations from the procedure in the text.

            e.         Data: This includes all the observations, measurements, etc… that you make in the laboratory.  The data should be presented in tabular form.  Check the report sheet to get ideas from the types of tables that are helpful for presenting data for that particular experiment.

            f.          Results: These include all the things that you have calculated from the data.  Note:  results are not calculations, but calculations based on data give results.

            g.         Discussion & Conclusions:  A short paragraph discussing the results of the experiment.  This section should answer the questions from the “Purpose” above.  This is the place to mention significant sources of error and the effect they have on the results


STUDENT LABORATORY PRACTICES AND RESPONSIBILITES

 

Laboratory safety is everybody’s responsibility. As a student in the chemistry lab you are responsible for understanding and following the guidelines below.  Failure to do so may result in a reduction in your laboratory grade.

Code of Academic Honor and Integrity

Los Angeles Mission College

Departments of Physical and Life Sciences

Students at Los Angeles Mission College, because they are members of an academic community dedicated to the achievement of excellence and the pursuit of honor, are expected to meet high standards of personal, ethical, and  professional conduct. These standards require personal integrity and a commitment to honesty. Without the ability to trust in these principles, an academic community and a civil society cannot exist. Los Angeles Mission College students and faculty are as committed to the development of students with honesty and integrity as they are to the academic and professional success of its students.

The Academic Code of Honor and Integrity is an undertaking of the students, both individually and collectively, that they will:

1.   Not give or receive unpermitted aid during exams, quizzes or assignments

2.   Not give or receive unpermitted aid in assignments, reports or any other course work that is to be used by the instructor as a basis for grading.

3.   Do their share and take an active part in upholding the spirit and letter of the Code of Academic Honor and Integrity.

Some examples of conduct that are regarded as being in violation of the Academic Honor Code include:

·         Copying from another’s examination or quiz, or allowing another to copy from one’s own papers

  • Using any unpermitted source of information, human or other, during an exam, quiz or assignment that influences the grade; this includes the use of technological devices
  • Any student-to-student collaboration that is unpermitted
  • Plagiarism (plagiarism is defined as the use, without giving reasonable and appropriate credit to, or acknowledging the author or source, of another person's original work)
  • Representing as one’s own work as the work of another
  • Giving or receiving aid on an academic assignment under circumstances in which a reasonable person should have known that such aid is not permitted

As a part of the effort to promote and instill an environment of honesty and integrity during quizzes and examinations, the following guidelines will apply for any courses in the Departments of Physical and Life Sciences:

1.   Students will leave all books and all other non-essential items (e.g. paper, electronic devices, phones etc...) on the floor or inside their backpacks so that they are not useable nor block the sight line between professor and student. No electronic devices will be in reach.

2.   Students will not communicate in any way that will dishonorably assist themselves or another student.

3.   Students will leave the room during an exam only if permitted by the professor’s policy.  If permitted, only one student may leave the room at any time and be gone for only the average length of time needed for the stated purpose.  Students will leave all purses, bags, books, phones, jackets, etc., in the classroom during the absence.

4.   Students will promote the spirit and letter of the Code of Academic Honesty and Integrity by dissuading fellow students from dishonest activity and, when such casual persuasion does not work, informing the professor of the possible dishonest activity, either anonymously, or otherwise.

5.   Students will make every effort to avoid the appearance of dishonesty or lack of integrity

Violation of this policy will not be tolerated and violators will be subject to penalties. The success of the Code of Academic Honor and Integrity is based upon the collective desire of students, faculty and the community to live in an environment that embraces respect for that which is right – both in the college and in society as a whole.

I have read and understand the Code of Academic Honor and Integrity and will abide by both its intent and its spirit:
