Student participation in inquiry serves two objectives—first, students discover that science is something more than merely learning what others already know—and second, students develop skills in interpreting data and in understanding scientific knowledge. This chapter presents six invitations for getting started with inquiry. Each invitation has two components. One is composed of information for students and the other contains student materials along with annotations and information for the teacher. The invitations can be used as independent learning experiences or in conjunction with laboratory exercises and with classroom work. Recommended guidelines for using each invitation to inquiry are provided in this chapter.
