Shaving cream is a great alternative to the Cool Whip! As long as you have kids who won’t eat it of course! 😂

Hi Claire,
Great question!
You will definitely want to have enough graham crackers and plates for each student or student pair, but you should be able to “re-use” the graham crackers and plates for the different plate movement demonstrations if you do the water one last.
Hope that helps!

Do I need to get enough graham crackers for a different plate/set-up for EACH different plate movement demonstration? Or can I use the same Cool Whip & Crackers for each if I do the water one last?

Just looking for the cheapest route! 🙂
Thanks!

Yup…you are right…I misread and went too fast..indeed, the MORE dense oceanic crust is thrust beneath the LESS dense continental crust. My bad. Rock on! By the way, I thought that to model this, you can wet the “oceanic crust” graham cracker so that it is easier to move the “continental crust” over it, thus making a visual (and conceptual) distinction between the two types of crust. Wet cracker s more dense than dry cracker!

Hi Maafi,

You’re right that the oceanic crust is thrust under the continental crust. However, everything I’ve read says the thick oceanic crust is more dense than the continental not less dense. The denser oceanic crust thus sinks under the less dense continental crust into the mantle.

Your so cool

Thanks!!!!!!!!
