Models, Analogues and Simulations

I am still a little confused as to how an analogue and model are different, but I'll take a stab at it. A model is something physical that you make to represent something else-and it is usually made to look like a smaller version of the real thing. An analogue is like a model in that it is representing something, but it uses different components than the real thing (i.e. like an analogy for something.) A simulation is the actual process of imitation. For instance, we simulated making different kinds of rocks in class: sedementary, metamorphic and igneous.
My group made rice krispy treats, which were analogous of sedementary rocks because there you could see the "sediments" (i.e. the puffed  rice) in the final product.The peanut brittle and sea foam I think are both analagous of igneous rocks because in order to get the final "rock" product, we had to melt the candy & then let it cool-just like igneous rocks.Although we didn't make butterfingers in class, we got to bite into one lengthwise and then observe what we saw. I think you were trying to show us how there are many different platey layers that look like they were fused together -analagous of a metamorphic rock formation.
