Igneous Rocks


Igneous Rocks

TEKS Objective

The student is expected to explore the processes that led to the formation of sedimentary rocks and fossil fuels.

Essential Understanding

The student knows Earth's surface is constantly changing and consists of useful resources.

Science Background

Rocks and Minerals: US Geological Survey (website) - Basic information about the types of rock, with particular attention to igneous rock formation, with pictures and text.

Signature Lesson

Igneous Rocks/Volcanoes: The Society for Mining, Metallurgy, and Exploration, Inc. (website) - Students differentiate between the two types of igneous rock and identify where they come from.

Supporting Lessons

Igneous Rocks: National Park Service (website) - This game allows students to act as molecules of rock minerals that solidify to form various igneous rocks.

Elaboration Lessons and Extensions

Igneous Rock: Rogers Group (website) - Students learn how igneous rock forms, and that there are different types of igneous rock (intrusive and extrusive). They also create an edible igneous rock model.

Assessment Ideas

Rock Data Sheet: K8 Science/BioEd Online (PDF) - Every rock holds clues to how it was formed. Geologists are like “rock detectives” who know how to read these clues and the stories each rock can tell. For this activity, students will receive sample of igneous rock to observe. As an assessment, have them write their own versions of how their rock samples formed and complete the Rock Data Sheet.
