Mad Art Lab: Art of the Gaps 2: Extraterrestrial Life? David Aguilar is an astrophysicist/artist with a passion for public outreach. He’s funneled all of these skills into several National Geographic popular science books of a kind that are like crack for curious kids. His book, "ALIEN WORLDS: YOUR GUIDE TO EXTRATERRESTRIAL LIFE," required a huge amount of research and speculation about the types of life that might be living on a wide variety of alien worlds. The research led to 3-D mock ups of organisms and lavish renderings of life forms set within their distinct alien environments. A teacher could easily develop an exciting multidisciplinary lesson plan with project from this book and video.
