Level: Undergraduate/adult Setting: Classroom Activity Type: Learning Cycle Discipline: Chemistry Course: Modified GOB chemistry keywords: buffer, buffer capacity, weak acid, conjugate base Abstract The GOB chemistry course is part of a biomedical workforce development program for adults with a wide range of backgrounds. A significant number of students have not studied chemistry before, or have a very basic middle school level. In the laboratory, students will learn to make biological buffer solutions, adjust the pH of a buffer solution by addition of acid or base, and utilize the concept of buffer capacity. This POGIL activity provides the students with a conceptual understanding of what is happening to the buffer upon addition of acid or base and why the buffer solution shows a smaller change in pH than a solution without any buffer. The particle diagrams are adapted from a tutorial created by Chem Collective: http://chemcollective.org/activities/tutorials/buffers/buffers1

|The Chem Activities found in Introductory Chemistry: A Guided Inquiry use the classroom guided inquiry approach and provide an excellent accompaniment to any one semester Introductory text. Designed to support Process Oriented Guided Inquiry Learning (POGIL), these materials provide a variety of ways to promote a student-focused, active classroom that range from cooperative learning to active student participation in a more traditional setting.If you are interested in having instructor resources please reach out to POGILKHrep@kendallhunt.com. Kendall Hunt is excited to partner with The POGIL Project to publish materials in a variety of disciplines that are designed for use in active learning, student-centered classrooms.POGIL is an acronym for Process Oriented Guided Inquiry Learning. Because POGIL is a student-centered instructional approach, in a typical POGIL classroom or laboratory, students work in small teams with the instructor acting as a facilitator. The student teams use specially designed activities that generally follow a learning cycle paradigm. These activities are designed to have three key characteristics:They are designed for use with self-managed teams that employ the instructor as a facilitator of learning rather than a source of information.They guide students through an exploration to construct understanding.They use discipline content to facilitate the development of important process skills, including higher-level thinking and the ability to learn and...
