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 Teacher's Edition, complete with facsimile pages of the student guide, placed exactly where you need them with the Teaching Strategies. In addition, the Teacher's Edition incorporates the following features, designed to help you organize and manage an activity-based science program within your busy teaching day. The Program Overview explains: the general philosophy, goals, and features of the program;the relationship of the program to the National Science Education Standards, including the content, teaching, and assessment standards, and Benchmarks for Science Literacy;the curriculum framework (scope and sequence)an instructional model, collaborative learning, communication skills, andclearly articulated assessment strategies;the structure of the student guide and resource book; andthe structure of the Teacher's Edition.
