Our family has really enjoyed this book which explains why leave fall off the trees before winter, where the different colors come from, how weather affects the brilliancy of the colors and lots more. It's written in a very simple manner, so that it's quite understandable even for preschoolers or kindergarteners, and yet it contains substantial information so that even moms (like me) realize that they don't know everything : ) You'll also find labeled pictures of the leaves from different kinds of trees, a cross section of a leaf, an explanation of how trees make food, and how to make leaf rubbings and preserve leaves by ironing them between sheets of waxed paper.
