Making Rocks

Sedimentary rock comes from the Latin word sedere “settle. Students can watch soil, pebbles, etc. in water settle to the bottom. They can be part of the beginning of new sedimentary rocks. It is an experience they can remember.

When I had access to a kitchen, I used to make “rocks” with my students. We made igneous lollipops from completely melted sugar boiled at high temperatures and then cooled. We always colored them bright red. The cooking process was more student observation than participation.

Biscotti are perfect for metamorphic cookies. They are baked twice resulting in hard cookies. Students love to roll and knead these! Use any recipe for a great result.

Layered cookies make great sedimentary cookies. Students can really participate here, poringon the layers. Here’s a recipe for a seven layer cookie.

1/2 cups graham cracker crumbs

1/2 cup butter or margarine, melted

1 (14 ounce) canEAGLE BRAND® Sweetened Condensed Milk

1 cup semi-sweet chocolate chips

1 cup butterscotch-flavored chips

1 1/3 cups flaked coconut

1 cup chopped nuts

Directions

Preheat oven to 350 degrees F (325 degrees F for glass baking pan).  In small bowl, combine graham cracker crumbs and butter; mix well.  Press crumb mixture firmly on bottom of 13×9-inch baking pan.
  1. Pour sweetened condensed milk evenly over crumb mixture.  Layer evenly with remaining ingredients; press down firmly with fork.
  2. Bake 25 minutes or until lightly browned.  Cool.  Chill if desired.  Cut into bars or diamonds.  Store covered at room temperature.

(You can change or leave out ingredience as needed to accommodate student allergy needs.)

The results were a great rock party. My students loved this day! They were able to remember information about the types of rocks from the cookies that we made. I think there is a definite stomach – brain connection.

Have a great weekend!
