Estimated Study Time Required Per Week: Students are expected to spend a minimum of two hours of student
time (reading, reviewing notes, and working homework problems) for each hour of class time (4x2 = 8 hours).
Course Requirements:
A.
Exams will account or 50% of total grade.
Four exams (100 points each) and 1 final exam (200 points) each semester. The final is comprehensive
and includes new material covered in the lectures during weeks 15 and 16 (material covered after exam
4). Either the lowest exam score will be dropped or if the final exam score is lowest, the final will count as
one exam rather than as two exams. All missed exams will be scored as zeroes. No retakes are
permitted.
Test questions may be:
1. True or False 2. Multiple Choice 3. Matching 4. Essay (i.e. word or numerical problem solving)
Tests will cover material from text, lecture, lab, and other presentations.
B. Quizzes/homework will account for 25% of the total grade
At least 10 in class quizzes will be given to assess student understanding of various concepts and to
evaluate student compliance with homework assignments. Expect to have a quiz on most Fridays;
additional quizzes may be given at any time. Graded homework assignments will count as quizzes. The
lowest quiz grade is dropped when calculating your grade. No retakes are permitted.
Homework must be submitted by 3:00 p.m. on the due date. Homework will be graded based on the
number for the problems reasonably attempted, and/or the correctness of the selected problems: work
must be shown to get credit. Complete sentences must be used where appropriate. Homework must
include your full name, course name/number, date due, chapter, and problem numbers on the assigned
homework problems sheet.
C. Laboratory – will account for 25% of the semester grade. The lowest lab grade will be dropped when
calculating your grade. The lab grade will be based on completeness and accuracy of lab reports
(including the correct use of written English), lab quizzes, and participation in laboratory activities.
Students are expected to work in groups of 2 unless otherwise instructed by your chemistry instructor.
Scores of unauthorized groups of more than 2 students will be divided by the number of students in that
group.
*Late homework and lab assignments will not be accepted unless otherwise prearranged with instructor.
Grading Scales/Grading Standards: Final class grades are a weighted average of exams (70%), laboratories (20%)
and quizzes (10%).
90-100% - A,
80-89% - B,
70-79% - C,
60-69% - D,
<60% - F
Factors that will influence grading in borderline cases: Attendance, class participation, punctuality and behavior in
class will all be considered when deciding grades in borderline cases. For example, your final class grade for the
semester is a 79.9. If you came to class regularly, participated in class, and were not disruptive in class you will
probably be given a B. If you have more than four unexcused absences, did not participate (attempt to answer
questions) or were disruptive (talking, etc) you will be awarded the C that you earned.

First calculate average scores
Tests: (80 + 85 + 90 + 92 + 92)/5 = 87.8
Drop the lowest exam score (79) (If the final exam is your lowest score it will count as one exam.)
Labs: drop the lowest lab (75)
(98 + 95 + 85 + 88 + 92 + 84 + 94 + 96 + 96)/9 = 92.0
Note: there will be about 14 labs
Quizzes: drop the lowest quiz (25)
(88 + 62 + 44 + 75 + 100 + 88 + 77 + 82 + 67 + 75 + 88)/11 = 76.9
Note: there will be about 15 quizzes
Next calculate weighted class average
Tests make up 70% of your grade 87.8 * 0.7 = 61.5
Labs make up 20%
"
92.0 * 0.2 = 18.4
Quizzes make up 10% "
76.9 * 0.1 = 7.7
The numerical grade is 61.5 + 18.4 + 7.7 = 87.6%
As per above, 87.6% is a "B".
Grades will be updated weekly in goedustar and quarter and final grades will be available at the end of each quarter.
NJC Assessment Goals:
In order to assure that students at NJC are gaining skills required to meet their academic, professional, and
personal goals and to assess the performance of NJC the following competencies are assessed in this class. Below
are the competencies and how they will be enhanced by this class.

Graduates will communicate effectively in written and oral form. Students in CHE 101 must use good
organization, correct grammar, and correct punctuation in crafting answers for all assignments. In order
for written work to be given full credit the requirement must be met.
Graduates will demonstrate critical and creative thinking skills. In CHE 101 students collect data, analyze
the quality of their data and use the data to explain the chemical phenomena observed or formulate rules
relating chemical phenomena. Students must select and use the appropriate mathematical equations to
solve problems and must analyze the values used in order to report results with the correct precision.
Students use their knowledge of chemical principles to extract the relevant information from word
problems in order to find the correct solutions.
Graduates will demonstrate proficiency in appropriate technologies. Students will be able to determine
mass, temperature and pressure to the highest precision of the instruments being used. Students use
computers to retrieve notes using either the classroom webpage or the S-drive. Students will
demonstrate proficiency in the use of scientific calculators by successfully using them to solve numerical
chemical problems.
Graduates will demonstrate an understanding of themselves as individuals and an awareness of ethical
issues. Students will explain why it is unethical to report scientific measurements to a higher precision
than that to which they were measured, describe some of the consequences of improperly disposing lab
reagents, and demonstrate care in the use of chemical reagents in order to prevent injury to themselves
and their classmates.
Graduates will recognize and understand diversity in our global society. Extra credit will be awarded to
students who participated in selected various diversity presentations offered by groups such as Student
Council and NHS. The nationalities of major personalities are made known to the student so that they will
appreciate that chemistry, and science in general, advances through the efforts of workers from around
the world.
Technology Requirements: Students will access class notes and PowerPoint presentations using the classroom
website and/or the school S-drive. Students will use goedustar to monitor their assignments and class grades.
Students will use a variety of chemical laboratory equipment (balances, graduated cylinders, etc) to collect data
and scientific calculators to carry out various computations and to aid in problem solving.
Tips for Success:
1. Take notes in class! Bring your text and calculator to class; we may work many computational problems in
class as a group.
2. Do the homework! It is important to practice the skills introduced in class outside of class so that you will
perform well in quizzes and exams.
3. Do the lab! Since lab makes up 20% of your grade, missing labs very rapidly diminishes your overall grade
in the class.
4. Get help early, if you have a low score on a quiz, lab, or exam come see me as soon as possible.
