Ciencia comestible: El ciclo de las rocas

This one-time class will combine two of my favorite things: science and food! We will use Oreos and other snack foods to demonstrate how each of the three types of rocks are formed, and the processes they go through to transform into one of the other types. 
Please note that the supplies are *optional.* I will be demonstrating in class, so students are welcome to just watch, or do the experiments along with me, at home. 
Also note: this could get messy, so I recommend putting down newspaper under your child's workspace. 
I will also be showing rock samples from this Rock Science Kit from Amazon: https://www.amazon.com/gp/aw/d/B002IF7NZU?ref=ppx_pt2_mob_b_prod_image. ($11.99)
This is also *optional* but helpful. They can use a print-out which shows similar rocks instead, or just follow along with me. 

Students will be encouraged, but not required, to participate in class discussions and experiments. 
*Class time given is approximate and can vary, depending on the amount of student interaction*
