Evolutionary Steps: A Stairway-Created Display of the History of Life.
Hedeen, Stanley E.
Journal of College Science Teaching, v27 n2 p119-20 Nov 1997
Describes an exercise whereby a biology class used a stairway to illustrate how fossiliferous rock strata were deposited, the oldest on the bottom and most recent at the top. Each step represents a dated boundary between adjacent geological ages, and each riser is labeled as a geological unit. Geological time is compressed to 365 days. Offers guidelines for adapting the display for shorter staircases. (PVD)
