Igneous Rock Activity

In talking about igneous rocks, we looked at the
cards from and talked about how
some lava cools quickly (like obsideon) and some
cools slowly (like granite).

Melting wax from a candle was like lava cooling
quickly and after the wax had cooled for a few
moments we felt how smooth it was and compared
that to the obsideon rocks we have from the rock

Don't miss our free 3 Types of Rocks worksheets that I made (when we studied rocks a few years after I wrote this post). There are also a lot of hands-on activity ideas in that post.
I shared some of our hands-on activities in these related posts:
