This Take a Stab! lesson plan also includes:
Your geology class practices taking core samples of a potato to examine the stratigraphy. This is a terrific modeling instructional activity that helps youngsters visualize strata that cannot be seen from the surface of the ground. The directions require each group to create their own potato strata, but if you have time, it would be even better to prepare the potatoes prior to student arrival so that they do not have preconceived expectations of what they will see in their core samples.
