Estonia is a rich of big rocks called boulders. Estonian boulders have been formed and moved into Estonia by glacial action during previous ice ages. Boulder are protected by the law. In Aruküla near to the Kindergarten stays Estonian sixth stone on the ground. Circumference 35,2 m and height 6,2 m.

We visited our famous stone with children. We said hello to the stone and felt its texture and temperature with cheeks and hands. We drew its pattern to the paper. We visited that place in the morning and we did some physical exercises there. Also we made some music by knocking smaller stones to the boulder and sang some songs.

We also noticed some moss and lichens growing on the stone. We explored them and the texture of stone with loupes. We discussed differences between moss and lichen and noticed that moss are growing only on the north side of the stone. Also we noticed that there were different small minerals on the boulder.
