Can the original material be recovered? - Paper 4

Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.

Read before answering

Change card: A crumpled sheet of paper is flattened but creases remain. Explain a recovery method and its limits. Reversible does not mean instant, effortless or a guarantee of perfect recovery. A physical change need not be easy to undo. Work from these descriptions; no child-led heating or mixing of unknown materials.
