Volcanoes & Mass Extinctions
Explain how large igneous provinces (LIPs) — massive outpourings of lava over millions of years — caused global warming and ocean acidification that drove mass extinctions; connect the Siberian Traps to the end-Permian extinction and the Deccan Traps to the end-Cretaceous event; explore how hydrothermal vents on the early Earth may have been the cradle of life; understand volcanoes as both destroyers and creators in the history of life
Lesson
Set out your lesson
“Volcanoes & Mass Extinctions 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 battery, bulb, and wires OR a warm/cool cup comparison setup
- Paper for a simple energy-path note
Extra for the adult
Worked example. Battery → wires → bulb: chemical energy becomes light (and some heat).
Optional challenge. For Volcanoes & Mass Extinctions, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Volcanoes & Mass Extinctions, not mastery.

“Can your child explain how enormous volcanic eruptions millions of years ago may have triggered some of Earth's biggest mass extinctions — what's the chain of events from lava to species dying out?”
