Rocks

Gavin has been very excited about polishing rocks lately, and requested to learn more about rocks as a theme week. 

I picked up some geodes at the planetarium for the kids to smash open.  They also collected 'normal' rocks to smash and compare.  I remember loving breaking rocks open as a kid.  I realized it is still fun, even as an adult.

Papa Finlay has a great collection of fossils, rocks and minerals.  Gavin and Elise's mom brought it all over to show the kids.

And they got to check out the collection of polished rocks from their Aunt Megan as well.

We used our collected rocks on tile for a rock-scratch test.  They found rocks that wrote in brown, black and white.

We made sugar crystal 'rock candy'.  The kids were very excited about checking it every day.  Gavin wanted green, but he also enjoys mixing colors, so instead of just using green food coloring, he was very happy to get to mix the blue and yellow.
