Course DescriptionExplores measurements, properties of matter, nomenclature, atomic theory, chemical periodicity, and chemical bonding. Prerequisites: MTH 111, WR 115, and RD 115 or equivalent placement test scores, and (CH 151 or pass the CH 151 Competency Exam). Recommended for the following majors and pre-professional degrees: chemistry, natural science, engineering, medicine and dentistry. This is the first course in a three course sequence. For information about the CH 151 Competency Exam see the description addendum in the CCOG. Audit available.

Chemistry 221 is the first of a three term chemistry sequence designed to provide a year of general chemistry to science majors (5 credits/term). It will meet transfer school requirements for such science majors as: chemistry, physics, chemical engineering, pre-medicine, and other pre-professional programs. The class consists of lecture and laboratory. The lecture time is used to provide the student with foundational chemical concepts and mathematical applications to chemistry. The laboratory re-enforces concepts presented in lecture and provides the student a hands-on opportunity to explore these.
Intended Outcomes for the course
Upon completion of this course the students should be able to:
- Demonstrate a basic ability to use effective written and/or oral communication through the application of general chemistry concepts and reasoning using the language of chemistry.
- Demonstrate an emerging understanding of how general chemistry impacts the natural and technological environments.
- Demonstrate a basic ability to use detailed data collection, analysis and collaborative skills in order to explore general chemical principles, critically evaluate models and information, draw conclusions and communicate results in the context of the material covered in General Chemistry I.
- Demonstrate an emerging understanding of chemical principles and collaborative skills to effectively solve problems encountered in general chemistry using appropriate computational and reasoning skills.
Outcome Assessment Strategies
PCC Core Outcome Mapping Core Outcome Communication - Mapping Level Indicator 2
Demonstrate a basic ability to use effective written and/or oral communication through the application of chemical concepts and reasoning using the language of chemistry.
PCC Core Outcome Mapping: Core Outcome Community and Environmental Responsibility - Mapping Level Indicator 1
Demonstrate limited understanding of how chemistry impacts the natural and technological environments.
PCC Core Outcome Mapping: Core Outcome Critical Thinking and Problem Solving - Mapping Level Indicator 2
Demonstrate a basic ability to use detailed data collection, analysis and collaborative skills in order to explore general chemical principles, critically evaluate models and information, draw conclusions and communicate results.
Core Outcome Mapping: Core Outcome Professional Competency - Mapping Level Indicator 1
Demonstrate limited understanding of chemical principles and collaborative skills to effectively solve problems encountered in general chemistry using appropriate computational and reasoning skills.
At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, laboratory write-ups, research papers, small group problem solving of questions arising from application of course concepts and concerns to actual experience, oral presentations, or maintenance of a personal lab manual.
At least two written lecture examinations, including the final examination, are scheduled during the term. Non-scheduled quizzes may occasionally be given at the discretion of the instructor. Written examinations include typical problems encountered in previous class work and laboratory. These examinations may also include challenge problems that ask students to apply concepts learned in class and lab in a new way in order to evaluate problem-solving ability and development of higher level thinking skills.
