**Who acts:** tiny things, surface, that, pond skater · **What happens:** not float, behave, be, walk · **To what, where:** all, water

<!-- .vabout -->
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 (tiny things, surface, that, pond skater), 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, R7-rel-agree ×2. **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.
