Active, Dormant & Extinct
Classify volcanoes as active (could erupt any time), dormant (sleeping but could wake up), or extinct (will not erupt again)
Lesson
Set out your lesson
“Active, Dormant & Extinct means classifying volcanoes as active, dormant, or extinct. We will practise once together, then check a fresh example.”
Bring to the table
- Three volcano status cards: active, dormant, extinct
- Simple volcano sketch or photo
Extra for the adult
Worked example. An active volcano could erupt any time. A dormant one is sleeping but could wake. An extinct one will not erupt again.
Optional challenge. For Active, Dormant & Extinct, add dormant as the middle case.
What to notice. Keep one parent note: volcano statuses sorted; support used. This session samples volcano status, not mastery of geology.

Check understanding
- Define active, dormant, and extinct volcanoes
- Explain that a dormant volcano is not safe just because it has not erupted recently
- Classify a given volcano based on its eruption history
“If you told your child about a volcano that last erupted 500 years ago, could they explain whether it's active, dormant, or extinct, and why a dormant volcano might still be dangerous?”
