    Stem Snacks - Domino Races

    glen_w

      Students were challenged to identify variables that change the rate dominoes fall. I helped students identify a control by placing all 28 dominoes in a line that was one meter long. Students could then experiment with their variables. They were reminded to ONLY test one variable at a time and to make sure they always used the full 28 domino set. It was fun to see the variety of designs used to make dominoes fall faster (and slower.) The fastest falling times resulted when students stacked their dominoes instead of just making rows. I’ve included a photo of the fastest design.

      What design would you use to get the slowest falling rate?
