In this article, the authors demonstrate how a simple math lab incorporating monthly height measurements can address multiple science and mathematics standards such as collecting, organizing, and describing data in context; drawing conclusions; and making hypotheses from these data. Although the yearlong math lab can be accomplished in either the mathematics or science classroom, a collaborative project shared by both classes may be the best way to show students the connection between mathematics and science. By incorporating technology in the long-term investigation, students take with them not only science and mathematics concepts but also life skills that they can readily use in many contexts.
