Sedimentary Rock

In these experiment students in room 6-A made peanut butter sandwiches. But these weren’t any old peanut butter sandwiches, they stood for sedimentary rocks. This experiment taught us about the way sedimentary rocks are formed.

Ingredients: White bread = fine grain layer

Chunky peanut butter = clay mud and rocks carried by floods andwater

Raisins & M&Ms = rocks, boulders, or large pieces of sediments

Fluff = calcium rich; produced by animal skeletons and shells

Wheat bread = the layer of silt with medium sized grains
