The Laboratory Manual for Introductory Geology provides an engaging way to learn geology, focusing on active exploration and real-life applications. Allan Ludman and Stephen Marshak are influential researchers and expert teachers who know how to make geoscience exciting for students. They introduce and reinforce key concepts and skills through rich illustrations, accessible explanations, intuitive labs with easy-to-follow instructions, and pedagogical tools that help students think like geologists. The manual’s modular chapters make it flexible and easy to assign with any introductory geology textbook, especially Marshak’s Earth: Portrait of a Planet and Essentials of Geology. To make the lab experience more dynamic, the manual is supported by interactive resources, including 3D models of geologic specimens, videos, animations, interactive simulations, and Google Earth activities.
