Evaporation & the Water Cycle
蒸发与水循环
Description
Identify the role of evaporation and condensation in the water cycle, and associate the rate of evaporation with temperature
Mastery Evidence
- Describe evaporation as liquid turning to gas and condensation as gas turning to liquid
- Explain the water cycle: evaporation from seas/lakes → condensation into clouds → precipitation
- Explain why evaporation happens faster at higher temperatures (e.g. puddles dry faster on hot days)
Assessment Prompt
Can your child explain why puddles disappear on a sunny day and where the water goes, and why the bathroom mirror steams up after a hot shower?
