Pluto: Ninth Planet or Not! Nine Models of Teaching! Nine Lessons!

Advanced Organizer for Educator Workshop

9 Big Questions/9 Models of Teaching/9 Lessons

The nine lessons presented here are shaped by nine models of teaching* --serving a two-fold purpose: first, to provide a thematic approach, built around the study of the Solar System, in this case focusing on nine big questions about Pluto; and second to provide a diversity of instructional approaches as a way to add breadth and depth to the teacher's repertoire.

Each model of teaching is described, follwed by a background discussion of the science content, and a walk though of the lesson itself. The first lesson (in the center) serves as an active introduction involving the whole group. Participants will explore the lessons described around the circle in smaller groups, to share later in a grand plenary culmination experience.
