In a society where technology plays an ever-increasing role, students' ability to understand the underlying science and make smart social and environmental decisions based on that knowledge is crucial. "Welcome to Nanoscience" helps biology, chemistry, and Earth science teachers introduce the revolutionary fields of nanoscience and nanotechnology to high school students through the unique framework of the environment, specifically groundwater pollution. This volume comprises two parts. The first provides background material for the teacher and answers important questions: What is nanoscience and technology? What are the important historical and societal aspects of nanotechnology? How is nanoscience related to environmental science? The first part also describes how education in nanoscience and nanotechnology addresses the National Science Education Standards and outlines the curriculum. Part II contains the five lessons: (1) Introduction to Nanotechnology; (2) Introduction to Water Pollution; (3) Microbe-Mineral Interactions: Using the Winogradsky Column to Demonstrate Bacterial Reduction of Iron (III); (4) Investigation of Bacterial Transport in Groundwater; and (5) Nanoforces in Nature: Using Atomic Force Microscopy to Explore Microbe-Mineral Interactions. Each classroom-tested, inquiry-based investigation follows the BSCS 5E Instructional Model and includes step-by-step procedures, materials lists, and data charts. Teachers may use the entire curriculum or pick and choose among its several parts, depending on their preferred emphasis, the course level, and available time. The flexible curriculum offers numerous entry and exit points. Also included is a link to a downloadable computer simulation program, which was specially designed to allow students to explore the atomic force microscope--even if their school doesn't have one. A glossary of scientific and technical terms and an index are included.
