If students develop an understanding of how science inquiry is done and how it contributes to understanding the natural world, they will be better prepared to analyze and interpret information throughout their lives. Merely telling students how knowledge arises from data and how it changes is not enough. Students must experience science in operation rather than just talk about science only as a summation of what has been demonstrated. The invitations to inquiry that follow are one useful means to helping students develop a deeper understanding of how science is done and what we can learn from science. They are teaching units that expose students to small samples of inquiry—samples suitable to their competence and knowledge.
