Crayon Rocks

Originally I put this up here.

Then on to do some science.  A while ago I had pinned a crayon rock idea from Momma Owl's Lab.   By the way, if you need an invite to Pinterest let me know I'll happily send you and invite.  :)

I figured this would be a good idea for a recovery day.   :)   This was a carry over from when we dug for gems and rocks a while back.
We had fun, we learned a lot.   

We grabbed our bag of old icky crayons.  It took a while to figure out the best way to shave them.  A knife wasn't a good idea so then we pulled out the vegetable peelers.  That worked better for the soft crayons, the hard crayons I just basically chipped into small pieces.

The first step was to make  Sedimentary rocks.  Layer shaved crayon, wrap in aluminum foil, put in clamp. :)

Then we moved on to Metamorphic rocks.    Knowing that these can be made through pressure or through heat we decided to see what would happen if we made sedimentary rock first and then heated it.  We also did one without putting pressure on it.  We had planned to do a third one and put pressure on it afterwards but after it melted we didn't see much point in doing that.  :)   But it was interesting since we did two of the three with double thickness aluminum foil and one with four times thickness.   The four times thickness melted much slower, the pressured one melted even more slowly.

When we finished these we moved on to making igneous rocks.   Igneous rocks are formed when magma (molten rock) cools and solidifies   The lad had a difficult time remembering what magma rock was  so I showed him this video.

Then he said "MELTED ROCK MOMMY!" 
We melted some rock.

Our end result had me wanting to crush a bunch of ice and do it all over again, but I ran out of energy and decided it could wait until another day.  :)
