“…The message that a science educator had sent to the educational community is a case in point: "determining what is appropriate physics for first graders is not trivial" (Hammer, 1999: p. 799). Indeed, given the growing interest in science activities for young children, even those in preschool education (e.g., Chaille & Britain, 2003;Fleer, 2009Fleer, , 2013Hong & Diamond, 2012;Kamii & DeVries, 1993;Kokoski & Downing-Leffler, 1995;Landry & Foreman, 1999;Leuchter, Saalbach, & Hardy, 2014;Peacock, Smith, & Kirkby, 1994;Waite-Stupiansky, 1997) the concern about what constitutes an appropriate physical science activity for a young child is a realistic one and should be seriously considered.…”
