Chapters 6–9 share model lessons for putting the explore-before-explain mindset into practice using either a POE (Predict, Observe, and Explain) or 5E (Engage, Explore, Explain, Elaborate, and Evaluate) instructional sequence. In this chapter, the model lesson is aimed at explaining why objects appear differently underwater versus out in the open. The model lessons illustrate how both the POE and 5E Models easily translate into the Next Generation Science Standards (NGSS) and allow you to see the POE or 5E Model and NGSS in action. Teacher background information, standards, and references are provided. This book selection also includes the Table of Contents, Foreword, Acknowledgments, About the Author, Introduction, and Index.
