- Minimize risk to self and others by adhering to documented and verbalized laboratory safety policies.
- Safely demonstrate basic laboratory skills including filtration, titration, observation and testing of properties of various unknowns, as well as use of a Bunsen burner, high-precision balances, and other basic equipment and glassware.
- Perform routine laboratory measurements including mass, volume, and temperature, and record them with proper precision and units; distinguish between measured quantities (raw data) and calculated quantities.
V. Academic Integrity and Student Conduct
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.
There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.
For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.
