Today, Ken and Althea helped us begin exploring rocks. We used Venn diagrams to consider ways of categorizing different qualities we observed in the rocks we found: color, size, texture. We also explored the usefulness of rocks as primitive tools, for grinding, cutting and abrading. We discovered that there were lots of rocks down at the wet bottom of our wooded hill and pretty much none up on the ridge and on the slope.
Looks like everyone had a great time and learned a lot!
