# Check the condensation claim

Design a paper comparison that would make a cold-container explanation more convincing. Include dry start and a sensible comparison.

## Try it

1. Draw a cool sealed container and a room-temperature comparison, both with dry outsides at the start.

2. Name what would be matched and how later outside drops would be recorded. Leave actual later results empty.

3. Check the product and say why you kept or changed one part. 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.

**Look for:** Name relevant matched conditions and a limitation; a paper plan does not prove an actual sealed container never leaks.

**Next help:** If the comparison lacks a dry start or matching conditions, add those first; a plan cannot establish that an actual container never leaked.
