In this lesson, students learn that scientists and engineers are resilient. They read about Marie Curie in the book Little People, Big Dreams: Marie Curie, by Isabel Sánchez Vegara. After reading, students will plan and conduct an investigation to describe and classify different kinds of materials based on their observable properties. This book selection highlights the practice of using mathematics and computational thinking, and it includes the Table of Contents, Foreword, Acknowledgments, About the Authors, and Index.
