Kids are interested in robots, especially young boys.  This book specifically addresses some of the robots used in the space program, and there are many.  At the end of the book are questions for critical thinking skills which use the common core, a great help for teachers.  The text is simple and directly explains the photo on the accompanying page.  I hadn’t realized Voyager 2 has been travelling through space for over 35 years–it’s amazing.  Students will enjoy this book and it’s photos and, who knows, it may lead to the creation of a future space robot.
