In this chapter, some of the Yes, but concerns are addressed. Some of the referents for the concerns lie beyond the Next Generation Science Standards (NGSS) and are the result of other variables, such as national politics, state budgets, or local priorities. With these acknowledged, the chapter provides clear and honest responses to the Yes, but concerns, especially to those that are frequently expressed. Teacher background information, standards, assessments, and references are provided. This book selection also includes the Table of Contents, Foreword, Preface, About the Author, Introduction, Appendix D, and Index.
