This chapter is designed to help students generate ideas for an investigation of their own and serves as a launching pad for science fair and science project work. Although this is the last chapter, some teachers may choose to use it first. The three lessons in this chapter progressively increase in difficulty and authenticity. The first invites students to review some successful science fair topics and use these as a springboard for their own ideas, the second focuses on the world around us as a source of interesting possibilities, and the third portrays the scientific literature as an authentic source of ideas.
