Earth Science: Plate Movement Hands-On Activities

  1. I’m trying this activity, but the sponges suck up the water as soon as I put them in, so they just sink and sit there. How do they move?

      Hi Morgen,

      Sorry not to get back to you sooner, I’ve been at a homeschool conference this weekend. We re-did this experiment in the fall with our science club and that happened with one of the groups when they didn’t have enough water in the pan… or maybe if the sponges were damp, but then wrung out so they weren’t sopping wet they would move like ours did away from one another. Another option is just to do it with two pieces of construction paper… same principle, but they definitely won’t sink! 🙂

      And then the other thing is to be sure to do the experiment about convection currents because when you do it with the immersion heater and ice bag, you can definitely see the dye moving through the water!

      I hope that helps!!
