INSTRUCTIONS
Form 10 -15 groups of five people.
Remaining people at tables are observers.
Group Role Assignments:
Group Manager - Person with last name starting with letter closest to A.
Manager will assign remaining group roles by distributing role cards from folder.

ACTIVITY 3 Purpose of the Activity:
To explore the different molecular conformations that can arise as a result of rotation about a C-C single bond, how conformers can impact the stability of the system in three dimensions, and to translate these findings into two-dimensional representations on paper.
Content Learning Goals:
Translate conformational information observed for atoms about specific bonds in three dimensions to Newman Projections on paper and predict the relative conformational stability.

OUTCOMES OF POGIL TEACHING METHOD
Students are actively engaged and thinking in class.
Students discover concepts (rather than memorize facts).
Students learn course content and practice key process skills.
13www.pogil.org
IS POGIL WORTH A TRY?
Tend to be lower failure rates.
Students typically learn just as much material.
Provides another avenue to focus on process.
Initial time investment.
Student buy-in varies.
