This activity is for investigating how heat changes things. Hand out some unpopped popcorn kernels to the children for observation. Then make some popcorn! This is a science investigation that they can eat so allow children to describe how it tastes and feels in their mouth as their first observations. Then guide children to smell and touch and look at the popcorn. A materials list, internet resources, standards, and safety practices are provided. This book selection also includes the Table of Contents, Preface, About the Editors, Introduction, Simple Graphing for Young Children, Science Teaching Boards and Boxes, Basic Materials List, and Index.
