6. Review What is homeostasis? How do unicellular organisms maintain homeostasis? What is the key organelle? How do multicellular organisms maintain homeostasis? What are some examples of your body maintaining homeostasis? What are the two kinds of feedback?

7. Body Systems Brain Pop We are going to begin exploring the body systems that work together to maintain homeostasis! Brain pop first…

8. Incredible Human Machine We will be watching more video clips and answering questions about many of the important body systems. Pay close attention! We will review/discuss the answers between each section. These videos can be found on the course website! www.commoncurriculum.com/website/j2u6/
