What are Igneous Rocks and How are They Formed?

Crystals form before your very eyes! What sixth grader wouldn't enjoy this lesson on igneous rock formation? Using hot Salol, junior geologists observe the crystal formation process as the material cools. This comprehensive lesson plan also walks them through the characteristics of both extrusive and intrusive samples of igneous rock. Eighteen pages of material leave you well-prepared to cover this topic in-depth.

I am in my last year of graduate school, and having to do observation, and student teaching has been great. Lesson Planet was one of the sites mentioned one day, since then I've gain so many new creative ideas through the lessons. Thank you Lesson Planet
