The cool display lidYear 4 Science · T1 W7–8 · Assessment / B later source · Text version

Made-up story. A pretend craft-display cabinet has two sealed containers whose outside lids begin dry. One container is cool and the other is at room temperature. Later the supplied picture shows small liquid drops on the cool outside lid and no visible drops on the comparison lid. The source provides no measured drop volume or humidity reading. Lea proposes that water vapour in the surrounding air changed to outside drops. The display is indoors and the story includes no cloud rain. You did not make these observations yourself.

Four questions

1. Which way does condensation change water?

2. Pick a clue supporting Lea's explanation.

3. Are these lid drops precipitation from a cloud? Explain.

4. Name one thing left unknown.
