- Igneous Rocks – Ignis is the Latin word for “fire”. These include Granite, Obsidian, and Basalt. Obsidian is an igneous, Volcanic Glass the Native Americans used for pottery and arrowheads. Notebooking Fairy has some great resources and free printables for Igneous Rocks HERE.
- Sedimentary Rocks – Sedimentary rocks are pieces of dissolved or broken up rocks, shells and minerals mixed up and smushed together to make new rocks. They include Shale, Sandstone, Limestone, Diatomaceous Earth, and Coal. Our favorite Sedimentary rocks are Geodes. They have pretty crystals inside them. These rocks remind us “for man looketh on the outward appearance, but the Lord looketh on the heart.” 1 Samuel 16:7b Again, check Notebooking Fairy for Sedimentary Rock printables HERE.
- Metamorphic Rocks – Meta means “change” and Morphe means “form” in Greek. These are rocks that went through some major changes, most of them probably in the Great Flood of Noah. They include Slate, Schist, Gneiss, Quartzite, and Marble. Notebooking Fairy’s Metamorphic printables are HERE.
Our children have always loved rocks. Rock hunting is like treasure hunting for us. We have rocks all over our house. Each of the children has several favorites. They have been with their dad a lot over the past few weeks and always find some treasures when they are with him. Our favorite rocks to find out here are probably the petrified wood. They’ve found some rather large pieces and are quite proud of them. The children love sharing their excitement with the old farmers and ranchers out here. Most of them have some fun and amazing stories to tell along with a nice rock collection of their own.
There are three basic classifications of rocks. I have to admit that Geology is not my strong suite. They all look like rocks to me! This is a bit of what the children are learning. My favorite book on the subject is: The Geology Book (Wonders of Creation) by Dr. John D. Morris
