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

¡Hoy los estudiantes probaron ser geólogos! Examinaron y describieron diez rocas diferentes, y luego usaron esas observaciones para tratar de clasificarlas como rocas ígneas, sedimentarias o metamórficas. Después de este primer intento, basándose en sus observaciones y conocimiento previo, utilizaron hojas de información ilustradas para investigar cómo y dónde se forman las diferentes rocas. Luego revisaron sus clasificaciones, identificaron las rocas y presentaron sus razonamientos a sus compañeros de clase. Tuvimos excelentes discusiones mientras los estudiantes analizaban los procesos en que un tipo de roca se convierte en otro tipo, en el interminable ciclo de las rocas

Vea si su hijo o hija puede encontrar un ejemplo de una de las rocas que estudiamos la próxima vez que estén de paseo. Muchos de los especímenes utilizados en clase ¡son rocas muy comunes!

Lauren earned a Bachelor’s degree with a double major of Biology and Psychology from Clark University, and a Master of Education from the Harvard Graduate School of Education. During her undergraduate years, she worked in a evolutionary neurobiology lab that studied the neural development of annelids (marine worms), with a focus on the sox family of genes. Lauren loves learning about how the world works (including everything from biology to chemistry to engineering), and is passionate about sharing that knowledge and enthusiasm with others. In the past, she has interned at the Museum of Science, where she educated learners of all ages through hands-on activities, games, and experiments. Other science education organizations with which Lauren has worked include The People’s Science, EurekaFest, and Eureka! of Girls Inc. of Worcester. Currently she lives in Boston, where devotes her free time to playing Quidditch, reading sci-fi novels, playing her ukulele, and enjoying all the culinary delights the city has to offer.
