Do Now ENGAGE YOUR BRAIN! YOU HAVE 7 minutes Before I start! TIC TOC! Complete the Engage Your Brain Do Now section in your packet for today. HOMEWORK: Homework: Pre-Read Igneous Rocks Worksheet Rock Cycle Pre-reading.
Today s Lesson: By the end of class today, all SWBAT classify igneous rocks based on their properties with at least 80% accuracy. Today s Skill: After this class, you should be able to: identify and group igneous rocks based on known characteristics of this type of rock
Igneous Rocks
Inquiry: See how much you already know! Observe the igneous rock on your desk. Describe what it looks like. Write down what each rock looks like in your notebook Igneous Rock is only one of three types of rocks. What do you think, from the example in front of you, makes a igneous rock igneous? How is it different from sedimentary and metamorphic?

Real Life: Igneous Rock Stone Mountain, GA
Igneous Rocks Igneous rocks form from the cooling of magma or lava of a Volcano Magma is molten (melted) rock inside the volcano Lava is molten rock outside of the volcano http://video.nationalgeographic.com/video/ player/environment/environment-naturaldisasters/volcanoes/volcanoes-101.html Play from 45 seconds to about 2 minutes
Examples of Igneous Rock: Granite Pumice
Intrusive Igneous Rock: Forms inside the Earth from magma because it is inside it cools very slowly causing it have large crystal structures and to be coarse and grainy Stone Mountain is an example of Intrusive Igneous!
Extrusive Igneous Rock Forms outside the Earth from lava because it is outside it cools rapidly causing it to be glassy & smooth and have small crystal structures or gas bubbles
Summary: Sort the characteristics of igneous rocks based on how they are classified in the chart below. extrusive intrusive glassy fine coarse
What are the most common igneous rocks?
Classifying Igneous Rocks Scientists can classify rocks based on the size of grains (particles of minerals or other rocks). EXTRUSIVE ROCK INTRUSIVE ROCK Formed from the SLOW cooling of magma below Earth s surface. Cools slowly, so minerals have time to grow larger Large-grained texture (coarsegrained).

Mystery Igneous Rock Lab
Group Activity 10 min Imagine that you are a grain of sand at the bottom of the river. Write an original story about your life that describes the changes that you have undergo as you become sedimentary rock, then a metamorphic rock. Continue your story by describing your journey to becoming an intrusive igneous rock. Each story should be at least 8 sentences. Points will be taken off if your story is not written in complete sentences. you = grain of sand How do you become a intrusive and extrusive igneous rock?
