Scientists ask questions to investigate all subjects, from what lies beyond our solar system to the tiny particles that make up all matter. The six-book Start with a Question set uses an engaging question-and-answer format to explore concepts and encourage readers to make their own science inquiries. Titles in the set are: Are All Zebra Patterns the Same?, Are Icebergs Salty?, Can a Train Fly?, Can People Feel Sound?, Is Peanut Butter a Liquid?, and What Is a Goldilocks Planet? Each book features author/illustrator biography, comprehension questions, educational front/back matter, full-color photographs, glossary of key words, index, informative sidebars, note to parents and educators, and table of contents. Downloadable Teacher Notes available.
