This chapter addresses the interpretation of data through graphs, maps, and cross-sections, which includes aspects of Developing and Using Models; Analyzing and Interpreting Data; Using Mathematics and Computational Thinking; Engaging in Argument From Evidence; and Obtaining, Evaluating, and Communicating Information. To understand a graph, it’s important to remember that graphs represent real world observations. Graphing is a language that turns an initially puzzling blizzard of real-world data into a coherent story. This chapter offers a quick journey through reading a graph. Here we walk through how to coach students in analyzing and interpreting their experimental data using graphs. A materials list, teacher background information, and outcomes are provided. This book selection includes the Table of Contents, Acknowledgments, About the Authors, About the Book, Introduction, and Index.
