Surface Tension

by: Donna Governor and Denise Webb

The guiding questions for this activity are,”How does surface tension affect movement in liquids and how many drops of water can a penny hold before the water slides off?” In this activity, students experiment with water striders and placing water drops on a penny. A detailed science behind the activity is provided. Students will also learn about cohesion. Before beginning this activity, we recommend you read Chapters 9 and 11 which are in this book selection. Chapter 9 is an overview of the section and introduces the format used to present ideas for Family Science Night activities. Chapter 11 features activities that we believe to be at an intermediate level. A materials list, references, safety notes, standards, and teacher background information are provided. This book selection also includes the Table of Contents, Preface, Acknowledgments, About the Authors, Introduction, and Index.
