for this sweet science experiment!
Halloween candy has so many marvelous uses.
Step #1: Choose two or three different kinds of chocolate treats. These represent the different kinds of rocks found on earth (sedimentary rock, igneous rock or older metamorphic rock). Step#2: Unwrap the candy (rocks) and place in a microwave safe container Note how different each candy bar looks although they are made from much the same elements. Step #3: Heat the chocolates - checking frequently. This represents the heat that comes from magma within the earth. Step#4: Smash the chocolates. This represents pressure from "tectonic processes such as continental collisions". Step #5: Pour the chocolate on to wax paper and let the new mixture cool. After just a brief wait, you'll see how the rocks (chocolates) have melded together to create a new form. These new rocks are called metamorphic rock because of the changes they have undergone. Step#6: Break open the rocks to see the newly formed layers. And yes... enjoy! |
