Successful completion of a high school or a college chemistry class with a lab component in the last 3 years. 

Course Description

Introduces measurements, classification and properties of matter, nomenclature, atomic structure and modern atomic theory, periodic table and chemical periodicity, and chemical bonding. This is the first course in a three course sequence. Recommended for chemistry and other natural science majors, and paraprofessional majors in engineering, medicine and dentistry. Recommended: Successful completion of a high school or a college chemistry class with a lab component in the last 3 years. Prerequisite/concurrent: WR 121 or WR 121Z, MTH 111. Audit available.

Course Outcomes

After successful completion of this course, students will be able to:

  1. Apply the fundamental principles of measurement, matter, atomic theory and chemical bonding to subsequent courses in chemistry, biology, physics, geology, engineering and various other related disciplines that depend upon these principles for comprehension.
  2. Apply the fundamental principles of measurement, matter, atomic theory and chemical bonding to their understanding of themselves and their natural and technological environments.
  3. Use mathematical and chemical reasoning skills, both qualitative and quantitative, to solve specific problems encountered in everyday life and professional settings.
  4. Use effective collaborative skills when working with other people to solve complex problems and accomplish tasks effectively.
  5. Use an understanding of written communication skills to effectively communicate complex scientific and technological ideas, models and conclusions through the generation of informal and formal writings and reports in a scientifically acceptable manner.
  6. Critically evaluate sources of scientific information to logically decide the bias, strengths and weaknesses of the information concerning the effect of chemistry and chemical concepts on themselves and their environment.

Alignment with Institutional Learning Outcomes

1. Communicate effectively using appropriate reading, writing, listening, and speaking skills. (Communication)
2. Creatively solve problems by using relevant methods of research, personal reflection, reasoning, and evaluation of information. (Critical thinking and Problem-Solving)
3. Extract, interpret, evaluate, communicate, and apply quantitative information and methods to solve problems, evaluate claims, and support decisions in their academic, professional and private lives. (Quantitative Literacy)
Not Addressed
4. Use an understanding of cultural differences to constructively address issues that arise in the workplace and community. (Cultural Awareness)
5. Recognize the consequences of human activity upon our social and natural world. (Community and Environmental Responsibility)

To establish an intentional learning environment, Institutional Learning Outcomes (ILOs) require a clear definition of instructional strategies, evidence of recurrent instruction, and employment of several assessment modes.

Major Designation

  1. The outcome is addressed recurrently in the curriculum, regularly enough to establish a thorough understanding.
  2. Students can demonstrate and are assessed on a thorough understanding of the outcome.
    • The course includes at least one assignment that can be assessed by applying the appropriate CLO rubric.

Minor Designation

  1. The outcome is addressed adequately in the curriculum, establishing fundamental understanding.
  2. Students can demonstrate and are assessed on a fundamental understanding of the outcome.
    • The course includes at least one assignment that can be assessed by applying the appropriate CLO rubric.

Suggested Outcome Assessment Strategies

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 assessment methods may include one or more of the following: examinations, quizzes, homework assignments, laboratory write-ups, research papers, small group problem solving, oral presentations or maintenance of a personal lab notebook.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Department Notes

Chemistry 221 is the first of a three term, 15-credit hour (5 hours/term), chemistry sequence designed to provide a year of general chemistry to science majors. 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, recitation and laboratory. The lecture time is used to provide the student with basic chemical concepts and mathematical applications to chemistry. The recitation time is for practicing problem solving in small group settings allowing for greater student-student as well as student-teacher contact and encouraging individual and team development. The laboratory re-enforces concepts presented in lecture and provides the student a hands-on opportunity to explore these.

Faculty effort in preparation and evaluation generally occurs outside of scheduled class hours. Class format is a combination of Faculty lectures and demonstrations, guided student interactions and supervised student application of lectures. Students produce written work such as lab notebooks, reports, and responses in writing to assigned questions, and the Instructor is expected to comment on and grade this written work outside of schedule class hours. This evaluation will take place on a regular basis throughout the term.

Columbia Gorge Community College Science Department stands by the following statement regarding science instruction:

Science is a fundamentally nondogmatic and self-correcting investigatory process. Theories (such as biological evolution and geologic time scale) are developed through scientific investigation and are not decided in advance. As such, scientific theories can be and often are modified and revised through observation and experimentation. “Creation science," “Intelligent design” or similar beliefs are not considered legitimate science but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F. 2d 1004).

The Science Department at Columbia Gorge Community College therefore stands with organizations such as the National Association of Biology Teachers in opposing the inclusion of pseudo-sciences in our science curricula except to reference and/or clarify its invalidity.
