Rockin' Out

This week, we started our exploration of rocks for science. At the beginning of the week, we wrote about and shared what we already knew about rocks:

Did you know...
  • rocks can be very big or very small
  • sand is made of tiny pieces of rock
  • some rocks are smooth and some are bumpy
  • some rocks have crystals inside
  • there are different types of rock--igneous, sedimentary, and metamorphic rock (we learned this in our nonfiction reading!)
  • some rocks have Micah
  • lots of things are made with rocks

We also came up with a list of questions we still had about them:

We are wondering...
  • Are some rocks harder than others?
  • How do rocks get smooth?
  • What kinds of rocks have crystals?
  • What kinds of rocks are shiny?
  • How many years does it take for a rock to become clay?
  • What kinds of rocks have fossils?
  • How far into the ground do you need to dig to find rocks with fossils of dinosaurs?
  • What are rocks made of?
  • How far do you need to dig to find diamonds?
  • What kinds of crystals are in rocks?
  • How many types of rocks are there?
While we can find many of the answers to these questions by looking in our nonfiction books and doing a bit of online research, we can also find some answers by doing a bit of exploring ourselves! We went on at rock hunt outside of our classroom to begin collecting some specimens on Wednesday:

On Thursday, we talked about different ways we could sort our rocks. After brainstorming lots of ideas for how we could sort our rocks, we each chose our own sorting method and came up with categories to sort our rocks into. After sorting our rocks, we went around the room to see how others chose to sort theirs:

We will continue to do some more exploring with our rocks and other rocks next week!
