Some atoms are radioactive and slowly change into other atoms at a steady rate, like sand falling through an hourglass.

Who acts: atoms, sand · What happens: be, change, fall · To what, where: other atoms, hourglass

This is a sentence of the lesson «Deep time and the story of life» of the geography course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (atoms, sand), what happens, when and where, as Mova's frames read it from the tree.
