These extension worksheets are perfect for raising the rigor in your Anatomy and Physiology class. They include opportunities for critical thinking, graphing and interpreting data, and using feedback loops and homeostasis within the context of body systems. These lessons can be used as homework pages, bell-ringers, sub plans or assignments for early finishers or honors students. ➤ PLEASE NOTE: All of the extension pages in this bundle are also part of my Full Anatomy & Physiology Curriculum.
