II. Course Description
Meeting for one three‐hour period each week, students will perform experiments, collect and analyze data,
and complete laboratory reports designed to complement the theory and concepts presented in the General
Chemistry I lecture.
Prerequisite: MATH 141 with 2.0 or better AND CHEM 139 with a 2.0 or better in the last 3 years OR
proficiency in all 5 sections of the Chemistry Placement Exam.
Student Learning Outcomes:
Students who successfully complete the course will be able to
• Develop basic skills for laboratory techniques and using laboratory equipment for measuring mass, volume,
and temperature, including acid‐base titrations
• Demonstrate proficiency collection data with the correct number of significant figures to reflect the
precision of the laboratory equipment used
• Work safely in the laboratory using common practices for handling equipment and chemical spills
• Maintain a laboratory notebook using accepted practices for science and engineering
• Write formal laboratory reports using the accepted format and practices for scientific reports
• The SCCC CHEM161 Fall 2011 Lab Manual (available at the SCCC Copy Center, BE 3105A)
• A new, bound composition notebook (with 80+ pages and none missing) to use as a laboratory notebook
• A USB Flash/thumb‐drive for saving laboratory data using a LabQuest system
• Students will also need a basic scientific, non‐programmable calculator that can perform exponential and
logarithmic (log and ln) functions.
IV. Course Requirements/Attendance
Attendance: Laboratory experiments require up to 3 hours in lab each week. Keep in mind that the lab may
take the entire 3‐hour period each week. Each experiment is set up for one week only and must be completed
during the lab period. No make‐up labs are allowed! Students missing more than two laboratory experiments
will receive a failing grade in the course.
It is important to keep a legible, organized notebook in science labs. Patents, lawsuits, and other legal matters
require well‐kept notebooks as evidence, resulting in the following rigid guidelines:
• Write in ink only, never in pencil. Never use white‐out!
• Record data in your notebook as you collect it—do NOT use scratch paper!
• A mistake should be crossed it out with a single line, so it is still legible, then initialed (see below).
This is the mistake. MV
• If an entire page is incorrect, just cross out the page with a large X and move to a clean page.
• Never tear out any pages from a lab notebook! All of the pages must remain intact.
• All calculations and other corrections should be made in the notebook as a record of your work.
• Keep in mind that pages from your lab notebook will be submitted with your final lab report.
• Keep your lab notebook neat and organized! Consider using the left‐hand side for calculations
and scratch work and the right‐hand side for the purpose, procedure, data, and results.
Pre‐Lab Assignments: Read through the entire experiment. The prelab consists of the following to be clearly
handwritten in your lab notebook:
• Title of experiment and date
• Statement of purpose in complete sentences
• A detailed description of the procedure (Note that students will NOT be allowed to refer to the CHEM 161
lab manual during the lab, so all of the necessary details to carry out the experiment, including safety
precautions, must be included in the lab notebook.)
Students who come to lab without preparing their lab notebook will be sent out of the lab to complete
the prelab before they can proceed. Repeat offenders will not be allowed to carry out the experiment
and will be given a “0” for each experiment they miss.
• Data tables for data to be collected during the experiment (refer to the lab manual)
• Many of the experiments may also include prelab pages from the lab manual to be submitted.
Pre‐Lab Assignments are due at the start of lab every MONDAY. Pre‐labs submitted after the start of but
during the lab will be penalized 10%. No pre‐labs will be accepted after the lab period.
The safety hazards for each experiment will be discussed at the start of the lab period, so students must
arrive to lab on time! Students who arrive more than 5 minutes after the start of lab may not be allowed
to complete the experiment and will be asked to leave.
Laboratory Safety: To maintain a safe laboratory environment, all students must adhere to the SCCC Chemistry
Department Rules and Regulations (see SCCC CHEM 161 Lab Manual). This includes wearing eye protection at all
times, unless otherwise instructed, and following standard laboratory procedures and protocols. Students who
endanger themselves or other students will be ejected from the lab.
Data Collection: Only record data you collect! To insure its authenticity, data must be recorded in non‐
erasable INK, not using a pencil. At the end of the lab period, students must obtain the instructor’s approval
and signature in their lab notebook before disposing of their chemicals and cleaning up their work area.
Post‐Lab Calculations and Analysis: After each experiment, students must complete all calculations and answer
all of the post‐lab questions following each experiment in the lab manual.
Lab Reports: Photocopies of the lab notebook pages with the data tables and the instructor’s signature should
be included with the post‐lab pages from the lab manual. Completed lab reports are due at the start of lab the
week after each experiment is completed.
Formal Lab Reports will be required for two experiments, “Volumetric Analysis” and “Calorimetry”. Details on
the requirements for each formal lab reports are included after each experiment in the CHEM 161 lab manual.
Grading: Lab Reports from the SCCC lab manual with Pre‐labs are worth 100 points total; formal lab reports are
worth 150 points total. Lab reports submitted during the lab will be penalized 10%, and lab reports submitted
after the scheduled lab period will be penalized 10% per day.
V. General Policies
Academic Honesty: Students may work together to discuss their results, but each student must submit his/her
own work. Students who submit data they did not collect or all students involved in copying pre‐lab or post‐lab
questions will receive a “0” on the pre‐lab assignment or lab report for the first offense. Repeated offenses will
result in a failing grade in the course.
