Extra Credit

Following the energy game show and a lively discussion, a middle school student shared an extra credit project with the class. He had constructed a model depicting how Geo-thermal energy is harvested from the earth. Using several layers of cake, frosting and sprinkles, the project represented various layers of the earth. Inserted from the surface downward are two straws to show how pipes go down into the earth to extract the Geo-thermal heat. When the student finished his presentation, he sliced up the cake and shared it with his classmates. Hopefully the 8th graders will remember what the model represented and not just the sweet afternoon treat in science class.
