DOUBLE TAP TO ZOOM ON PHONE OR TABLET
Dedication This book is dedicated to the thousands of teachers who have inspired and
encouraged our work—who work with creativity, energy, and empathy to
bring all children to their personal best. In the past few years, we have had the
pleasure of collaborating with many talented educators, who have generously
shared their insights and practical tips with us.

Thanks also to our husbands, who have helped us as we’ve worked with
these educators. We have traveled the United States and the world, and they’ve
always been alongside us, supporting science education in their own ways.

And, of course, we dedicate this book to children everywhere who are
empowered by their STEM adventures. These explorers are our future. May
their endless questions keep us young!
