This is a really fun and factual book about Mars. This book puts you in the story! The story refers to you, and how you will travel to Mars! I really love that children will see themselves in this book. They will see themselves travel to, and explore mars. This book contains a ton of facts such as "the gravity on Mars is only one third as strong as the gravity on earth." This is a wonderful book for science class. I really enjoyed reading this text. ( )
