2nd Grade Explores River Rocks!

2nd grade has moved from igneous rocks to river rocks!  They have been observing and sorting river rocks by different properties: color, shape, luster, size, and texture.  What happens when the rocks get wet?  Do their properties change?

 

We noticed that the river rocks had
so many colors in each rock.

Some rocks surprised us!  "Look a crystal!"

We wondered what would happen to the river rocks when they got wet.  Would there be bubbles like some of the volcanic rocks?

Some of the dull river rocks turned shiney
when they got wet.

Sorting wet river rocks by color.

No bubbles, but when some of the rocks got wet, they showed additional colors in the rock that we didn't originally see.


After exploring the river rocks, we sorted them one last time to make a Rock Museum!

This museum included a map!

In half the Museum you were allowed to touch,
the other half you just had to look!
