From the ingenious mind of Rachel Ignotofsky, author and illustrator of the New York Times best-selling book, Women in Science, comes The Wondrous Workings of Planet Earth 2020 Wall Calendar, an illustrated tour of the planet through art, maps, and infographics. Based on Rachel’s book, `The Wondrous Workings of Planet Earth`, this calendar will delight and inspire science- and nature-loving readers of all ages. Each colorful monthly spread features a fun and informative illustration that explores an ecosystem large or small, from a reef, a desert, or a rainforest to a single drop of water!
