Based on Rachel Carson's book "Silent Spring" and other conservation-related books, this lesson plan presents activities designed to help students understand that many conservationists have written books that have had a profound influence on the way people think about and treat the planet; such books can be powerful instruments for change; and reading such books and encouraging others to read them are important parts of being an environmentally responsible individual. The main activity of the lesson involves reading conservation-related books and writing a brief essay explaining the effects of their books might have had on science or society and their own personal reactions to what they read. It includes objectives, materials, procedures, adaptations, discussion questions, evaluation methods, extension activities, annotations of suggested readings and web links, vocabulary, and related academic standards and benchmarks addressed in the lesson plan. The lesson plan also contains a description of a video clip related to the lesson, comprehension questions related to the video clip, and answers to those comprehension questions. (RS)
