Exploring The Functions And Structure Of The Skeletal System Through Chicken Bone Analysis

Keelyn Purcell, a 7th-grade science teacher, introduces a lesson on the skeletal system. The class agenda includes note-taking, a true or false activity, a think-pair-share, and a chicken bone analysis. Students engage in various activities to understand the functions of the skeletal system. The lesson emphasizes time management, group roles, and effective transitions. The teacher uses countdowns and time prompts to keep students on track. The lesson concludes with a discussion on the importance of bones and the teacher's passion for teaching science.
