Intro to rocks day : models represent something real

We have been give a rice Krispie treat, a piece of peanut brittle and a butterfinger to look at. Each one of these candies can be a model when looking at the rock cycle.

identifying a rock. the first step is to put it into one of the three major rock groups, igneous, sedimentary, or metamorphic. Each group of rock has its own information chart to look at in more detail. You look at the rock and compare it to an information chart in order to identify characteristics of the rock. Something that would help with identification is if you add pictures in order to have a comparison to visually look at.

So the butterfinger represents a igneous rock because it has different textures inside of it. it also varies in color depending on what part of the candy you are looking at.

the peanut brittle represents a sedimentary rock. I say this because it has bits of pieces formed together to make one larger piece. The peanuts show the different bits.

the rice krispie shows a metamorphic rock. It is sort of layered and it was formed through heat, and pressure then cooling together.
