Today in science, we read a little bit about the different types of rocks. I remembered back to a day several years ago when a friend had given me some fun recipes to help the kids remember how the rocks are formed. Thanks, Melanie, for a memorable and yummy day in science!
Igneous rocks – cereal balls
Air is trapped in the cereal much like air gets trapped in pumice when that molten rock cools quickly. Melt 1/3 cup margarine with a 10 oz. package of marshmallows. Stir in 6 1/2 cups of crispy cereal. If you teach mafic and felsic, use chocolate cereal and regular cereal. Form mixture into balls and place on waxed paper.

Sedimentary rock – layer bars
Each ingredient represents a different layer of sediment. Preheat the oven to 350 degrees. In a 13" by 9" pan, melt 1/2 cup of margarine. Sprinkle 1 1/2 cups graham cracker crumbs over the margarine. Pour one can of sweetened condensed milk evenly over the crumbs. Top with 1 cup chocolate chips, 1 1/3 cups coconut, and 1 cup chopped nuts. Press down firmly. Bake for 25 minutes. Cut into bars.

Metamorphic rock
Place 12 oz. of white chocolate bark and 12 oz. of chocolate chips in separate bowls. Melt each in the microwave for 2-3 minutes. Pour the white chocolate onto waxed paper, then swirl in the chocolate chips. Refrigerate until hard. Break into pieces to serve.
