Somewhere between a text and a tutor GEODe: Earth Science version 3 DVD, included with your book, employs the unique capabilities of the computer to illuminate key concepts in Earth science. Animations, videos, photographs, text, narration, and interactive exercises are presented in a tutorial format. Do you learn better by doing? Exercises throughout the DVD get you interactinginstead of just memorizing. Does your lab not always parallel your lecture? A quick review of the relevant module will help you prepare you for your lab, whether or not you have covered the topic in lecture. Look for the GEODe: Earth Science icon throughout the text. The DVD is plug-and-play–no special software or installation is necessary–so it’s perfect for use in your school’s computer lab (though you should probably use headphones).
