All together, the document spells out six lesson plans for an approximately two-week unit on "gravity and motion". This unit serves as a component of a larger PYP unit entitled "The Solar System" in which the central idea includes the concept of how gravity governs the movements of the components of the Solar System.
While the intended level is Grade 2, the lessons could certainly be used for older students, either as-is or with modifications to "beef up" the content.
