A briefer version of the highly successful Biology: Life on Earth, 6/e (2002), Life on Earth, 3/e was developed in collaboration with a team of biology educators to meet the needs of non-majors. It is built on a steadfast tradition of accurate science, engaging presentation and media innovation. The new MediaTutor student CD-ROM is integrated into each chapter, as MediaTutor Tabs within each chapter show a sequence of activities found on the students' CD. For the instructor, a new Instructor's Resource CD-ROM conveniently provides all the tools needed to prepare for lecture in one easy-to-use CD. The result is a program that helps you draw students into biology through an engaging text, interactive media and exciting lecture presentation material.
