Sedimentary Rock!

While learning about Sedimentary rock, we made a yummy model! Sedimentary rock is formed by the compaction and cementation of sediments. Sediments come from other rocks being weathered. Our model represented the formation of sediementary rock, but we got to use food!
First, We weathered Graham crackers in tiny crumbs!

We then added other types of sediment (Sugar!) and Fossil fuels (butter)! We pressed our sediements in the pie pan and put them into the toaster oven to bake. Our rocks came out hard and tasty!
This model Rocked!!

  1. LOVE this idea! Where did you find the chocolate "lava"? Also, did you use a certain amount of butter for the sedimentary rocks? I'm hoping to do this with my class this week. I can't wait!

  2. How much butter and sugar!
