Changes you can undo and changes you can't, sentence 3

Chemists look for clues that something new has formed: a new colour, bubbles of gas, light or heat, a new smell, or a change that will not go back.

Who acts: Chemists, something, change · What happens: look, form, not go back · To what, where: clues

This is a sentence of the lesson «Changes you can undo and changes you can't» 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 (Chemists, something, change), what happens, when and where, as Mova's frames read it from the tree.
