This accessible and exciting reference book covers the key questions across key topics, from science and history, to space and the human body

This perfect first reference book brings key subjects - such as science, geography, and history - to life. Lavish 3D digital illustrations and an interactive question-and-answer format together create an engaging and accessible insight into a number of key topics.

Why? Encyclopedia focuses on the subjects children really want to know about. It covers all of the areas you would expect in a kids' encyclopedia - including space, animals and the human body - but presents each through questions kids ask, such as "Why does it rain?". Answers are provided through a combination of eye-catching CGI artworks, enhanced photographs, and clear text explanations.

This refreshed version of the first book in a hugely successful series (over 650,000 copies sold worldwide) brings the latest updates in ever-changing topics, such as space exploration, as well as a number of new pages on interesting topics, including artificial intelligence, climate change, pandemics, and gravity.
