Title: Plate Tectonics With An Orange
Core Content for Assessment:
Objective: To acquaint the student with the concept of plate tectonics.
Have the students peel the orange without the use of a knife and in as few pieces as possible. This peel represents the earths crust and the crust is in pieces just like the orange peel.
Have the students lay the orange peel on their work surface and record their observations.
Tell the students to replace the peel on the orange, securing the peel with toothpicks.
Since most of the fault lines on the earths crust are not visible, the students may wish to roll out a thin piece of clay (or play dough) and cover the orange. They should carefully remove the toothpicks as the clay is placed.
