Floating in the real world: ice, submarines and balloons, sentence 1

Water is strange: it grows bigger when it freezes, so ice is lighter for its size than water and floats, which saves fish in frozen ponds.

Who acts: Water, ice · What happens: be, grow, freeze, float, save · To what, where: fish, frozen ponds

This is a sentence of the lesson «Floating in the real world: ice, submarines and balloons» of the physics 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 (Water, ice), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R5-strong ×2, R8-pos-agree ×3. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
