__**Igneous Rocks**__ media type="file" key="8.wav" width="300" height="50" I chose the topic igneous rocks because I wanted to learn more about them. There are three types of rocks, igneous, sedimentary and metamorphic. You can find igneous rocks everywhere a volcano is or was. Igneous rock is lava that has cooled and hardened. Sometimes animals can get trapped when the lava flows down the volcano. About fifty years later, the animal will be a fossil! Igneous rock is not very hard because it comes from lava. Igneous rocks can be hollow or solid, it depends on how fast the lava cools. When the lava cools fast, no crystals can form, and the rock looks like glass and is very shiny. (some bubbles can get trapped in the lava when it's cooling.) 'Igneous' means: made from fire, because it's made from the lava from volcano. Now you can see why igneous igneous rocks are so interesting!

__Comments from Teachers during the research process:__


 * Note from Mr. Kleyn. What do you mean when you say "google?" How do you spell the word that starts with "ig?" Interesting question. Do you think this question will be easy to find an answer?

Note from Mr. VanOrden: You've come up with many interesting questions! I'm looking forward to seeing what you learn. I read that the word "igneous" comes from a Greek word for fire. I wonder why we use that word to describe certain types of rocks.

Note from Mrs. Smith: Excellent work on explaining that igneous is a type of rock formation, and how it occurs. You've chosen some very interesting facts to include in your writing. I can certainly see why this was an interesting topic for you to research!
