At the start of this module, students are given a mysterious gray object: an owl pellet. They examine it and find many small bones inside. Three questions, "What are bones?", "Whose bones are they?", and "Where do they come from?" focus the investigations.

Learning experiences that explore human bone groups, teeth, and joints, as well as the skeletons of other animals help students develop an understanding of bone structure and its relationship to function.

Writing is an integral part of learning science in the Insights curriculum, and a critical skill used by scientists. One of the most important tools of the scientist is the science notebook. In this notebook, students will record questions and predictions; observations and data; and interpretations and conclusions. Students may also use this notebook for informal sketches, notes, and reflections on work.
