Learning About Rocks!!

Today we went to the science lab. Our teachers gave us new rocks. The rocks were from a river bed. But, we don't know what river they came from. When we put the rocks in the water they got shiny. Some rocks are like crystals. They were very shiny and pretty. Some rocks when they get wet got darker. Some rocks had lines or patterns on them. There were rocks with white and black in them. The water got really murky. Some rocks even had dots. Some students sorted their rocks by size. Other students sorted their rocks by colors. The rocks when they were wet felt smooth. They were also very hard rocks. When the rocks came out of the water again they were cold. Some rocks looked very interesting.
