    Default Rock Cycle Treats

    We did this in my classroom this week. Give each child a mixture of milk
    chocolate chips, white chocolate chips, and peanut butter or butterscotch
    chips. These represent rocks. Let each child pour the rocks in a covered
    container and shake it up to weather the rocks. Now you have sediment.
    Pour the sediment into plastic baggies and give it a gentle press. You
    have made a sedimentary rock. Now, squeeze and press the baggie with
    lots of pressure. That makes a metamorphic rock. At this point, you are
    supposed to gather up all of the metamorphic rocks and melt them in a
    crockpot or microwave to represent magma. I didn't want everyone sharing
    germs, so I let them eat their own metamorphic rock and melted another
    bag of chocolate chips. Pour the magma into molds or spread it on waxed
    paper to cool. Now you have made an igneous rock.

    nothing like keeping the kiddies all hyped up with candy.

    Did you have them rip the white ones in half to demonstrate crack
    rocks?

    And it came to pass that Tara delivered the following message unto the
    people, saying~

    I remember doing something kind of like that in fifth grade, circa 1994/5
    or so. The teacher also had demonstrated magma by making some sort of
    "fudge" concoction (didn't have marshmallow creme, so it didn't really
    "set up") which was later shared amongst the class.

    <oldfart>Of course, even then it was still not considered "un-politically
    correct" to give kids sweets, even in school. You know, since people then
    weren't nearly as anal as they are about it now...</oldfart>
