Rock On!

In third grade, we have started our unit on rocks and minerals. We have been geologists testing for crystals and identifying different types that are found in our mock rocks. We detected kosher salt due to the square nature of the crystal formation with an X running through the crystal. Our I/E group will be testing other crystal formations to share with everyone.
