This is a sentence of the lesson «Molecules: when atoms join up» of the chemistry 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 (H2O, that), what happens, when and where, as Mova's frames read it from the tree.
