Soil is common to all of us, so common that few people think about it and its importance in our everyday lives. The activity presented here provides an analogy useful for helping students design experiments and explore how soil particle size affects its behavior. Originally a simple “cookbook” demonstration for community college students, we restructured it to be more inquiry oriented so that it mentally engages students and promotes several important goals for science teaching. We believe the modified activity is applicable across a broad grade/age range, perhaps from upper elementary to some introductory post-secondary science courses. This activity promotes National Science Education Content Standards A, B, D, and E, and Iowa Teaching Standards 2, 3, 4 and 6.
