Great book with a lot of good information. The graphics are engaging and provide the right amount of information. We use in our homeschool and for fun.I bought the 2 book set, 1-5 and 6-10. I liked the illustrations, and I do feel they had good information, written in a way that's easy to grasp, …, but I just didn't think they were worth $100. They're good for a short little blip of learning, but I felt we would need to add another option to dig deeper into most topics, and for the price, I would've liked a little more heft.This book is AWESOME! My kid loves it!A great introduction to the science for kids.great book for big and small :) kids enjoy it a lot when we read it together
