Start: “Where could these outside drops come from?”
Purpose: Explain condensation as vapour becoming liquid droplets and use a comparison clue carefully.
Prepare
Read today's complete model and two contexts before the session. Paper, a pencil and the full written picture words are sufficient. Optional actual water work follows ordinary preparation; the teacher chooses suitable familiar materials/instruments. Use today's three routes without assigning a fixed learning-style label.
Run the session
-
Reconnect: use the invisible vapour card; gas in air is water even when no drops are visible.
-
Model: supplied source shows two dry sealed containers at the start, one cool and one room-temperature. Later tiny outside drops are shown on the cool one. Condensation is a supported explanation; this is not a leak test proving every wet container has the same cause.
-
Try: sort labels “vapour in surrounding air”, “cool outside surface”, “liquid drops”. Optional adult-prepared safe sealed cool container observation uses a towel, no touching requirement and actual before/after records.
-
Compare: ask why a dry starting outside, sealed top and comparison container help. If conditions are not matched or a spill occurs, record that limitation. We do not force a visible result.
-
Make: label the direction vapour → condensation → liquid drops. Explain that these outside drops are not precipitation from a cloud.
-
Exit: “Condensation changes __ into . The supplied clue is .” Retain source access.
Three ways in
Outside-drop diagram
Label the given sealed-cup comparison without touching water; use the written source table when the picture is hard to see.
Worked ordinary reasoning: Vapour in air changes into drops on the cool outside surface; condensation is supported by the supplied dry-start comparison.
Watch and record
Observe the teacher-prepared containers and dictate a before/after observation; describe whether drops actually appeared, including no visible change.
Worked ordinary reasoning: I saw __ on the outside at __; if nothing appeared I record that rather than copying the model result.
Direction puzzle
Choose which of two arrows fits “outside droplets formed”: liquid→gas or gas→liquid, then give the scientific name.
Worked ordinary reasoning: Gas→liquid; condensation. This source does not measure how many drops formed.
Look and choose the next teaching
Correct state direction, relevant supplied/actual clue and no rain/leak overclaim.
For a reversed arrow, compare this direction to Day 32 and use new bottle/window examples.
