The Water Cycle

水循环

Description

Understand the water cycle: the Sun heats water in oceans and lakes causing it to evaporate into water vapour, the vapour rises and cools to form clouds (condensation), and water falls back to Earth as rain, snow, or hail (precipitation) — then the cycle repeats

Mastery Evidence

✓ Name the three main stages: evaporation, condensation, precipitation
✓ Explain the Sun's role in driving the water cycle
✓ Describe the water cycle as a continuous loop with no beginning or end

Assessment Prompt

Can your child trace the journey of a raindrop — from the ocean being heated by the Sun, rising as invisible vapour, forming a cloud, and falling back down as rain — and explain it keeps going round and round?
