Course Description
Ch2 is the accompanying laboratory course to Ch1. This class is intended for non-science undergraduate
students desiring a simple, clear but broad understanding of chemical principles and their impact on
our lives. The laboratory aims to provide students with real world hands-on laboratory examples of the
chemistry in their everyday lives. Experiments are designed to make chemistry interesting and
informative so students develop positive attitudes of towards chemistry and science.
Learning Outcomes
At the end of the course, the student should be able to:
1. Correctly apply the scientific method: making qualitative and quantitative observations,
presenting technical data effectively, and make critical interpretations of results and discuss
these results using the modern theories of chemistry as well as creating clear, logical, and
scientifically sound experimental designs to solve simple chemical problems;
2. Demonstrate fundamental chemistry laboratory skills such as handling glassware, balances, and
burners;
3. Apply the protocol on proper use of chemicals, especially safety and waste disposal;
4. Use procedures for good scientific reporting/writing;
5. Apply chemical concepts discussed in the general chemistry lecture class;
6. Perform basic chemical calculations;
7. Apply skills to possible applications in Philippine entrepreneurial & industrial setting.

Course Requirements
By the second meeting, the students must bring the following:



Lab Gown/ Apron (to be kept in lab locker)
Laboratory notebook (green spiral, 216 x 280 MM)
Each group of 4 around a lab sink must bring masking tape for labels, paper towels or wipers to
clean spills and the lab tables
Pre-laboratory Report
1. Make a detailed flow chart of the experimental procedure for wet laboratory experiments. This
is accomplished individually and presented to the instructor for checking before the start of the
experiment. No pre-laboratory report merits a deduction under Laboratory Performance.
Laboratory Reports
1. Immediately write data in the worksheet using a pen (NOT a pencil). Do not memorize data
for later recording, or do not write data in a scrap paper for later transfer in the worksheet.
Improper documentation will merit a deduction.
2. Do not use a correction tape to erase incorrect data. Rather, cross them out using a single
line. Improper erasure of data will merit a deduction.
3. The total score for the laboratory report will vary depending on the nature of the experiment.
4. Unless otherwise specified, worksheets should be submitted at the end of each laboratory
period, and these will serve as your attendance. One worksheet per sink, unless otherwise
stated.
5. Late submissions will not be accepted.
6. Strictly no cheating. Any form of academic dishonesty (such as generating false data and
plagiarism) will get a grade of zero in the laboratory report. The maximum penalty allowed by
the University will also be pursued.
Laboratory Performance
2. At the start of each experiment, the student will have a perfect score for the laboratory
performance. Deductions will be given whenever a student does not follow the procedure, does
not handle the glassware properly, does not follow proper laboratory behavior, and other acts
stipulated in this syllabus.
Quizzes
1. A 5- or 10-point quiz will be at the start of every class (except during days of reporting) to see
if the student has a basic understanding of what the experiment will be about (e.g. procedure,
precautions, etc).
2. If a student is late or absent and misses the quiz, s/he will get a zero for the quiz.
2
3. It is possible for the class to accumulate more than 10 quizzes for the semester. In the event that
more than 10 quizzes are taken, only the highest ten quizzes will be counted for the final grade.
4. Strictly no cheating. Anyone caught cheating will get a grade of zero in that particular quiz. The
maximum penalty allowed by the University will also be pursued.
Group Reports
1. The class will be divided into small groups. Each group will be given a maximum of 20 minutes
(plus 5 minutes question/answer) to report on an experiment (experiments with similar and
related theories will be grouped together).
2. On the scheduled date, the group will discuss the theoretical basis of the experiment and relate
it to similar processes, a local industry, a local social issue, or a local environmental issue, etc.
3. Groups will draw lots to determine the experiments to be discussed during the scheduled dates.
There will be a total of two reports per group for the semester.
4. The grading will be as follows:
a. Accurate and thorough discussion of chemistry concepts
and answer questions related to the topic
b. Ability to relate concepts in other fields/applications
c. Creativity
d. Ability to engage the audience (at least they are listening)
Final Project
– 20 points
– 10 points
– 15 points
– 5 points
50 points each
1. The final project is an ice cream making activity (Make Your Own Ice Cream).
2. Group assignments will be the same as the previous group reports.
3. Other specific details of the activity will be discussed as a class at a later date.
4. The final project will be worth 100 points.

Important Guidelines
Attendance and Punctuality
1. A maximum of two (2) cuts is allowed for the entire semester. There is no distinction between
an excused and an unexcused cut.
2. A student must be present during the pre-lab discussion. If s/he is late during the discussion, 10
points will be deducted from the lab performance. If s/he misses the whole lab discussion, s/he
is not allowed to perform the experiment and will get a zero for the said activity.
3. There will be no make-up lab activities. If there is a valid reason for the absence (i.e. serious
illness, school-related engagement, etc.), the student must secure the necessary documents (i.e.
medical certificate, letter from the ADAA) and give it to the teacher as soon as possible.If the
excuse is deemed valid, the total score for that experiment will not be included in the final
grade.

Laboratory Attire
1. Students must wear protective clothing during the laboratory activities. This includes shirts
with sleeves, jeans or long trousers, and closed shoes. Boiling liquids (water, acids, etc) can
squirt a meter or more while dropped glassware fragments will explode out and hit your feet
when dropped.
2. Those who are not properly dressed (i.e. wearing sleeveless shirts, shorts, skirt, shoes that
show any skin on the feet) will not be allowed to perform the experiment, and will be
marked absent.
3. Students must also wear apron and goggles at all times. If a student is caught not wearing
apron or goggles, s/he will receive a deduction in the laboratory performance.
Laboratory Safety
1. Safety guidelines will be provided during check-in, and students are expected to know them by
heart. For any doubt, feel free to approach the teacher.
2. Treat every chemical employed in the laboratory with caution. Avoid direct contact with
reagents. You can have a terrible allergic reaction.
3. Immediately report any accident to the teacher.
4. No horse playing inside the laboratory.
5. To avoid accidents, keep the equipment and working area clean.
6. Close all gas valves after the laboratory activity.
7. Do not forget your locker combination. If a student forgets the combination, s/he can ask the
stockroom technician for it, but will merit a deduction in the laboratory performance.
8. After leaving the laboratory, each student is highly encouraged to pass by the comfort room to
wash their hands before resuming to other activities.
Demeanor
1. Cellular phones, laptops, PDAs, and iPods must not be used and must be turned off during class.
2. Only calculators can be used to make computations.
3. Eating and drinking are not allowed inside the laboratory. It is dangerous because of
poisonous chemicals in the lab and on countertops which can make you very sick or kill
you.
