This document discusses how wind can move objects and provides an activity and assessment for students to demonstrate their understanding. It begins with identifying different forces, like wind, that can make objects move. Then it provides criteria for students to follow to create a working wind wheel out of materials provided. Finally, it discusses how wind moves other objects, lists some key concepts, and assigns students to draw a wind wheel and objects moved by wind for assessment, as well as gathering pictures of windmills that generate electricity for a future assignment.
