Earth's Frozen Water
Understand the cryosphere and its role in Earth's water system — the cryosphere is all frozen water on Earth (ice sheets, glaciers, sea ice, permafrost, snow cover); polar ice sheets hold about 69% of Earth's fresh water; if all polar ice melted, sea levels would rise over 65 metres; and the water cycle connects polar ice to the global system through evaporation, precipitation, and meltwater flowing into oceans
Lesson
Set out your lesson
“Earth's Frozen Water means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A habitat photo or short fact card
- Paper for a features list
Extra for the adult
Worked example. Thick fur helps Arctic animals keep heat in the cold.
Optional challenge. For Earth's Frozen Water, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Earth's Frozen Water, not mastery.

Earth's Frozen Water means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A habitat photo or short fact card; Paper for a features list. 1. Say the goal of Earth's Frozen Water in plain words once. 2. Adult names one habitat feature and one way a living thing is suited to it. 3. Child lists three features or adaptations and matches each to survival. 4. Fresh check: one fresh adaptation match. Record and stop. Done: three feature–survival matches. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Define the cryosphere as all frozen water on Earth and name its components: ice sheets, glaciers, sea ice, permafrost, snow
- State that polar ice sheets hold approximately 69% of Earth's fresh water
- Explain how polar ice connects to the global water cycle and what would happen if it all melted (65m+ sea level rise)
“Does your child know that most of Earth's fresh water is actually locked up as ice at the poles — and that if it all melted, the sea would rise over 65 metres, flooding coastal cities worldwide?”
