EROSION Demonstration!

Yesterday, we started discussing types of rocks. We talked about sedimentary rocks and how they are tiny bits of sediment compacted together over the years. Sediment results from EROSION so we set up water dripping onto to a mineral salt block. This is what we saw happen. It ERODED and left behind sediment. They thought it was too COOL!
