LIFE SCIENCE-During the course of this module, the students explore the characteristics of guppies, snails, and aquatic plants in classroom aquaria. By observing those organisms in their environment, the students learn about what organisms need to survive. They recognize that the structures of the organisms serve specific functions that enable them to survive in their environments. Then, they extend their understanding of organisms' needs and ability to survive in their environments by investigating the characteristics and behaviors of gerbils and isopods. They recognize that an animal's behavior and structures enable it to meet its needs and that animals can survive only in environments in which they can meet their needs. BSCS Science Tracks includes a comprehensive Student Guide and resource book at every level, 1-5. The Student Guide is not a "read-about-science" book; rather, it serves as a guide to help students learn to do the following things. Conduct scientific inquiries within a collaborative team and on their own Become more responsible for their own learning Manage the hands-on activities themselves Structure collaborative learning tasks Develop science and technology concepts and skills Reflect on their learning and assess their own conceptual and skill development Conduct independent inquiries related to questions or topics of personal interest Develop skills for reading in the content areas Follow and interpret directions In addition, the Student Guides reinforce components of basic literacy, including shared reading and writing, guided reading and writing, continuous assessment, skills instruction, reading procedural text, listening and speaking skills, journal writing, record keeping, hints and reminders, reading and writing in a social context, and reading and writing in a content area.
