Deep-Sea Survival
Explain how deep-sea animals cope with crushing pressure (no gas-filled spaces, flexible proteins, pressure-adapted enzymes); describe thermoregulation extremes — antifreeze glycoproteins in Antarctic fish, supercooling in wood frogs; introduce tardigrades and cryptobiosis (surviving desiccation, extreme temperatures, radiation, vacuum); survey other extremophiles (thermophiles at hydrothermal vents, halophiles in salt flats); consider what these organisms tell us about the limits of life
Lesson
Set out your lesson
“Deep-Sea Survival means practising the idea at the table with real materials and one clear check. We will demo once, then your child tries.”
Bring to the table
- Picture or object cards for Deep-Sea Survival
- Paper and a pencil
Extra for the adult
Worked example. Adult shows one clear example for Deep-Sea Survival, then the child tries a matching example with a reason. Larger handwriting would not change the idea.
Optional challenge. For Deep-Sea Survival, add one harder example after success.
What to notice. Keep one parent note: examples tried; reasons; support used. This session samples Deep-Sea Survival, not mastery.

Check understanding
No checks listed
“Can your child describe an animal that can survive being frozen solid, completely dried out, or exposed to the vacuum of space — and explain roughly how it manages to survive conditions that would kill almost any other living thing?”
