My son was asking different questions about the Earth and this book was the perfect surprise for him. He’s only 5 so he loved all the different interactive features on every page. We read it together and it was just the right amount of information for him to understand. 100% recommend for curious little minds!

Great Earth Science Resource

Format: Hardcover

We purchased this book to go along with our homeschooling Earth science curriculum. This book did not disappoint! Such engaging pop ups that really interested my kiddos. I’m teaching age ranges 7-12 and all of them enjoyed this book. I think the pop ups are something different so it grabbed their attention! I would recommend this book.

Fun Interactive Book

Format: Hardcover
