We are getting everything for our upcoming learning expo. We are practicing doing some of our rock activities again so we can show our visitors how to do them.
Today we classified rocks into their three groups just like scientists do. We had long, involved and enaged debates about which catergory or ‘family’ we thought each rock went in.
Long discussions were had as to whether pumice could be rock when it was so light
