General Description of Each Lecture or Discussion
Students will be required to participate in and complete the following:
1. Students will participate in lecture activities including discussions, quizzes and in class assignments
2. Students will turn in assigned homework problems and questions
3. Students may participate in optional cooperative learning groups
4. Students will participate in laboratory experiments and turn in laboratory reports
5. Students will complete four unit exams and one comprehensive final exam
6. Students will participate in a service learning project
Methods of Instruction/Course Format/Delivery
The following components will be used to calculate a final grade for each student:
1. Homework - for the course will consist mainly of problems and questions from the text. Homework will be completed and turned in using an online system called Sapling Learning. This online access pass MUST be purchased separately online. This system is separate from Canvas.
For homework to be most useful in preparing for in class work and exams, it must be submitted by the date due. Late work is not accepted.
2. Lecture Activities – are exercises performed in class as a participation in the
lesson, quizzes and optional participation in chemistry seminars. No late or makeup
work will be accepted for lecture activities except in the case of student participation
in a Panola College student activity that has been approved by the college.
Study Groups - are recommended to encourage peer tutoring and cooperative learning. Groups will form by student choice and meet at times chosen by the group. Reports of study group activity will be turned in to me once a month for extra credit in the lecture activities grade portion.
3. Laboratory Experiments – Laboratory experiments will be performed in order to apply the general principles, laws and theories of chemistry learned during lecture. Experimental results will be recorded and submitted on the forms found
in the lab manual. Lab expectations will be discussed in the laboratory orientation by your lab instructor. Course information states additional rules and expectations that must be followed and the consequences that will result.
The grade of 100 possible points for each laboratory experiment is broken down as follows:
- 10 points for showing up on time with the pre-lab assignment complete and an up to date MSDS notebook containing all required safety information. This is your ticket in the door and you will not begin an experiment without it.
- 40 points for conducting the experiment, adhering to all safety and equipment use rules, completing the experiment, cleaning up your lab station, and disposing of all waste, trash according to instructions given. All of these items must be complete before leaving lab.
- 50 points for the report sheet you turn in. It must be complete, legible, and information must be properly presented and clearly explained when necessary. All work must be shown when necessary.
4. Unit Exams – Four unit exams are given throughout the semester that are worth 100
points each. Each written exam will be given during a regular lecture class period.
No one coming in late may start an exam after the first person has left and extra
time will not be given. One unit exam may be made up at the end of the semester at
a time designated by the instructor. The make up exam is comprehensive and all essay/problems.
Online students will take proctored written exams at one of the three testing centers
offered by Panola College.
A tentative schedule for unit exams is as follows (see the lecture schedule for dates):
Unit I Chapters 1, 2
Unit II Chapters 3, 4, 5
Unit III Chapters 6, 7
Unit IV Chapters 8, 9, 10
5. Final Exam – is also comprehensive and will be administered according to the posted final exam schedule in December. No one coming in late may start a final exam after the first person has left. Anyone late for the final will not be allowed any additional time to complete it.
6. Attendance – is expected at all lectures and labs. Class attendance is monitored and recorded. See the handbook for rules concerning allowed absences. If the role sheet has already been turned into me, you are absent. Tardies disrupt instruction and need to be avoided to the best of your ability.
Each student will complete the following project during the semester:
Participate in a service learning project by volunteering for 4 hours in an area that can be related to chemistry. (Everything relates to chemistry.) You are responsible for finding the place of service, but help will be provided and you will be in contact with me and the chosen mentor to determine your role.
- All volunteer work must be approved in advance by me. More information will be provided in the next couple of weeks.
- You will serve in whatever capacity they need you.
- You will write a reflection paper about the experience to turn in to me.
- All volunteer work, reflections and presentations must be completed by the due date.
Additional instructions and due dates will be provided at a later time. This project is worth 250 points and is a part of your laboratory grade.I reserve the right to make any changes to this syllabus according to what is deemed best for student learning and success in CHEM 1405.
I believe chemistry is a core discipline essential to a college education regardless of major or career choice. Recognizing a broad range of interests, preparations, and future needs among chemistry students, this course is designed to allow each student
to individually select topics for various assignments in order to further develop possible career choices. Every attempt on my part is made to ensure your area of interest is discussed. Please let me know if there is a topic that particularly interests you. Organization is a key to success in this course. I highly recommend a notebook or three ring binder to keep up with all assignments, quizzes, homework and exams. For example, if there is a problem with the homework system and you can show me your work, I am able to give you credit.
This course is available on Canvas and will contain useful information like conversion charts and formulas, specific course objectives by chapter for test review, assignments, laboratory experiments, copies of handouts, tutorial sites and ACS
