This activity compares different kinds of candy to the different types of rocks based on direct observation. A great number of geologic processes either take unimaginable lengths of time to complete, or happen in places that cannot be directly observed, such as under the Earth's crust. It is, therefore, necessary for an Earth science teacher to find a connection between students' experiences and the geologic process they are studying to help them better understand that which is often unobservable. One Earth science topic with a tendency to be beyond the reach of direct observation for students is rock formation.
Ideas For Use
The main goal of this activity is for students to figure out how the various types of rock are formed, so it is best to select candy samples that show physical characteristics similar to the characteristics of each rock category. Although it is impossible to select samples that cover all of the observable characteristics, the goal is for students to make the initial connection rather than an all-encompassing description of how each rock type is made.
