More rocks. :D
I forgot to mention that when we made the sedimentary rocks, we also made metamorphic rocks by squishing together different colors of Starbursts. Best rocks I have ever eaten!
This morning, we took a walk down to the creek to find some more rocks. Toby and Lucy insisted on joining us.
We did rock testing after we got home. We tested the hardness (with a series of scratch tests), magnetic qualities, the streak test (does it mark on a ceramic tile?), and the acid test (this one tests for Calcium Carbonate in the rock. Apparently, in North Texas, we have a LOT of rocks with Calcium Carbonate. All but 1 of our 10 rocks that we tested tested positive for this one).
