This activity is for using the sense of smell to observe and identify different scents. At the start, discuss with the students how our sense of smell is very important and can help us identify different objects. Then distribute one set of “smelly cans” to each group of children and have them smell the cans and describe the scents. Encourage them to compare the scents. 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.
