Change the unassessed caption “water disappeared forever” so it gives a possible scientific explanation.

Practice caption to improve: “The water disappeared forever.” No amount or other-loss record is supplied.

A helper can read the caption and record your intended words. Keep fresh assessment stories closed.

Try one small explanation, then stop or return later. Tell or show it in your usual way: words, drawing, pointing, signing, typing, dictation or your communication device. Work quietly or privately, pause, ask for a helper, or return later. Sharing and recording are optional.

**Useful response:** Some liquid water could evaporate into water vapour; less visible water alone leaves other possibilities. No equipment purchase, water handling, trip or private household data is required. Keep this ordinary practice separate from new assessment sources.
