Description: Based on materials from Encyclopaedia Britannica, published by the Chicago-based Encyclopaedia Britannica Company, this book organizes essential curriculum content that Korean elementary school students need to know into a structured learning system. Rather than separating humanities and social studies from natural science, it presents comprehensive knowledge related to each topic, helping to nurture creative individuals with both humanistic imagination and scientific understanding. Large amounts of information are presented through visual images rather than lengthy, tedious text. The infographic at the beginning of the book summarizes the core content in diagrams and illustrations, sparking readers' interest. The comic-style main text, which explains learning content in an entertaining way, along with a variety of photographic images, will help readers quickly absorb information and remember it for a long time. Furthermore, rather than simply listing fragmented pieces of information, the book portrays the characters in the comic pursuing positive values based on what they've learned and experienced. Readers will encounter stories about cherishing the environment, respecting differences, and considering the common good of humanity. Prologue: A Visit to the Dinosaur Museum! (p.8) 01.
