"Take a close look. What do you see? It's called lichen- made of fungi and algae." This delightful book is part of a series of books that encourages children of all ages to pause and look closely at nature. The book contains photographs taken by the author, Dr. Josie Zayac, who has been an educator for over 30 years. With a sing-song rhythm of rhyming couplets and a page of facts about the National Park at the end, this book is perfect for preschool children, elementary classes, and English Language Learners. Look for other Close Up books by Dr. Josie Zayac to learn about other National Parks. You'll want to collect them all.
