In this activity about endoskeletons (page 8 of PDF), learners observe, compare and contrast different kinds of chicken bones, and relate their chicken bone observations to human bones. The bones must be prepared a day ahead of time. Learners also use a poem to identify the major bones of the human body and discuss the importance of bilateral symmetry. This guide includes background information, extensions, and data sheets.
