We transitioned from investigating the types and uses of different resources all over the country with our Native American studies to Mountains and Plains resources of Colorado and finally the basics of Geology.
All students have been introduced to the rock cycle: Igneous, Sedimentary and Metamorphic. They will begin to act as Geologists with tests such as luster, streak, scratch, cleavage and basic mineral identification.
PK sorted rocks by look- streaks and strips, holes and cracks, smooth and shiny, sparkles and crystals and size and shape.
YK- Sorted sediment by size from Boulder, cobble, pebble, granule, sand, silt and clay. The biggest to smallest was easy, but matching names to size was more of a challenge. They then sorted a variety of tricky pictures such as brick, diamond, kitty litter, quartz, turquoise or shell and fossil into ROCK NOT ROCK categories which raised some great questions and further investigation.
MK- had the same ROCK NOT ROCK activity and broke into groups to further investigate rocks such as quartz, sandstone, pumice, granite, obsidian and limestone to figure out if these rocks were Igneous, Sedimentary or Metamorphic. This will be our introduction to next weeks mineral identification and classification.
OK first started with identifying the 4 types of mountains to learn how each were formed and understand the story of how rock forms, moves and morphs from state to state. We used this information to help with our rock cycle understanding and will take this a step further with mineral identification. Once we understand the relationship with all three we will be well on our way to reading the landscape and understanding the story left behind when we dive into fossils and prehistoric time periods.
