Las Rocas Nos Cuentan (Rocks Tell Their Stories)
Llerandi-Roman, Pablo A.
Science Teacher, v79 n4 p49-52 Apr 2012
Many Earth science lessons today still focus on memorizing the names of rocks and minerals. This led the author to develop a lesson that reveals the fascinating stories told by rocks through the study of their physical properties. He first designed the lesson for Puerto Rican teachers, hence its Spanish title: "Las Rocas Nos Cuentan Su Historia." Through guided inquiry, students can discover the literal and figurative meaning of those words. In this article, the author explains how to implement and expand the lesson to address higher-level concepts. He also suggests teaching approaches that worked in his secondary and college classrooms. Finally, he shares student worksheets in both English and Spanish, which include key questions and instructions for the observation, description, measurement, and classification of rock and mineral samples.
