In this edition of Miller's ENVIRONMENTAL SCIENCE, a new Student CD-ROM, INTERACTIVE CONCEPTS IN ENVIRONMENTAL SCIENCE, has been added! This groundbreaking addition integrates nearly 100 engaging animations and interactions with chapter summaries, flashcards, and Web-based quizzes. Organized by chapter, students will find links to relevant resources, narrated animations, interactive figures, and prompts to review material and test themselves. The animations show complex processes and relationships unfolding on screen, such as the effects of acid rain, smog formation, and the phosphorus cycle. Narration allows students to focus on what is changing on screen while interactions allow students to explore figures in more depth.
