蒸发与水循环
Evaporation & the Water Cycle
识别蒸发和凝结在水循环中的作用，并将蒸发速率与温度联系起来
Identify the role of evaporation and condensation in the water cycle, and associate the rate of evaporation with temperature
学习证据 / Evidence
- 将蒸发描述为液体变成气体，将凝结描述为气体变成液体
- 解释水循环：海水或湖泊中的水蒸发，凝结成云，再形成降水
- 解释为什么温度越高蒸发越快（例如：天热时水坑干得更快）
- 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)
评估问题 / Assessment
{{name}}能解释为什么晴朗的日子里水坑会消失，水去了哪里，以及为什么热水淋浴后浴室镜子会蒙上水汽吗？
Can {{name}} explain why puddles disappear on a sunny day and where the water goes, and why the bathroom mirror steams up after a hot shower?
