tree creatures and the permeability of clay

Withycombe Raleigh Primary came to West Town to explore soils and clay on the farm. We tracked our journey using a satellite image, waded through the stream, crossed muddy fields and ended up at Tree Henge.[gallery link="file" columns="4"]
There is a really good link to be made with Science and Art! Along the journey we stopped to observe first hand, in the hand and a very muddy hand it was by the end! Particles, organic matter, rock, pebble and permeability all emerged as a working vocabulary. Tea strainers allowed us to test permeability out in the field and answer the question "Why was the water staying in the Tree Henge's moat?" Then clay became a resource for creation as we mixed different colours, added gathered materials and finally our Tree Creatures guarding the trees. I hope that, by the end, the children had a far deeper understanding of what clay is.
This is part of a developing series of stories about the resources we have on the farm. Wood, Water, Pumpkins, Pigs and more all have their story to tell of change and use through direct experience. Certainly this process is a good learning opportunity for me!
