Young children love exploring the beach to find shiny, colorful rocks. Now Hello, World! can teach them all about rocks and minerals-with colors, shapes, sizes, and super-simple facts. ("Do you draw with a pencil? The part that makes a line on your paper is graphite. That's a mineral!") Told in easy-to-understand terms alongside bright, cheerful illustrations, Hello, World! makes learning easy for babies and toddlers and offers useful prompts to adults to help them engage with the reader on each page. It's a perfect way to bring the outside world of natural science into the busy world of a toddler, where learning never stops.
