We want to thank our wonderful PTA for bringing the High Tech High Touch program to our classroom last week. We really loved having a real scientist visit us and teach us about rocks. 
We got to mine for real gemstones.
We search hard through our bowls and dug up all kinds of cool stones.
We rinsed them off in the "river".
We took our rocks back to our classroom and sorted and classified them according to luster, color and shape.
We had to look very carefully at each rock to decide which group it belonged in.
We tested the gemstones to see if they were magnetic.
We also go to see if each gemstone had a "secret" inside of it. 
The secret was limestone.
If the rock had limestone it would bubble in the vinegar.
On Friday afternoon we made chalk! It was lots of messy fun!
We stirred and stirred and stirred.
Then we each put some into our cupcake cup.
And this week we will get to write with our special rocks!
What a fun week of learning about rocks!
