Rocks and Soil

 We have been studying about rocks and soils.  We learned about the different properties of rocks: color, hardness, luster, and texture.  We talked about the different kinds of rocks also.  As an experiment we filled our water bottles with dirt from the playground and added water.  We let it sit overnight, and when we came back to school, our water bottles looked different.  We predicted that there would be mud in our bottles the next day.  Much to our surprise, we found that the dirt had settled, and we saw different layers.  The mulch floated to the top, and the sand to the very bottom.
