Rock Cycle

Today students tried their hands at being geologists! They examined and described ten different rocks, and then used those observations to attempt to classify them as igneous, sedimentary, or metamorphic rocks. After this first attempt, based on their observations and prior knowledge, they used illustrated information sheets to do research on how and where different rocks are formed. They then revised their classifications, identified the rocks, and presented their reasoning to their classmates. We had some good discussions as students thought about the processes that can turn one rock into another, in the never-ending Rock Cycle.

See if your student can find an example of one of the rocks we studied next time you’re walking around outside – many specimens were examples of very common rocks!

El ciclo de las rocas, una dura realidad

En la clase de ciencias del día de hoy hablamos sobre las rocas. Primero hablamos sobre las distintas capas de la Tierra, y luego aprendimos sobre el ciclo de las rocas y sobre las tres categorías de rocas que existen (sedimentarias, ígneas y metamórficas). Discutimos cómo las rocas en la Tierra están en constante cambio debido a la erosión y a los cambios de presión y temperatura. Los estudiantes lograron comprender cómo se forman los distintos tipos de roca gracias a que examinaron y identificaron diversas muestras de rocas. Los alumnos también aprendieron sobre las diferencias entre los minerales y las rocas.
