One of the best ways to understand school science as inquiry is through a visit to a classroom where scientific inquiry is practiced. The following vignette features a particular grade, but, as illustrated throughout this book, classroom inquiry can and does happen at all grade levels. Sidebars point out some ways inquiry is occurring.
Several of the children in Mrs. Graham’s fifth grade class were excited when they returned to their room after recess one fall day. They pulled their teacher over to a window, pointed outside, and said, “We noticed something about the trees on the playground.
