Book excerpt: What would it be like for a kid to tour our solar system? In this clever trip through the solar system, a diverse group of girls and boys explore every planet with their robot guide, Dr. Quasar. Facts about our galaxy, solar system, the sun, and each planet are revealed as the kids visit Mercury, Venus, Earth and its moon, through the asteroid belt, on to the planets in the outer reaches of the solar system, and finally to the dwarf planet Pluto. Scientifically accurate, full-color illustrations show young readers the difference between planets, comets, asteroids, and other parts of the universe. As the kids write funny postcards home, they share more facts about each planet in an appealing kid-friendly way that helps introduce space and the unique aspects of our solar system. A short list of "space words" at the back of the book reminds readers about important concepts and vocabulary. Great for classroom use to introduce the solar system and space as well as for young explorers interested in space and science.
