Volcanoes for Kids (3rd Grade Science)
Volcanoes are a gateway drug to loving science. Kids learn what magma and lava are (same rock, different address), why eruptions happen, and the parts of a volcano from magma chamber to crater.
Sample practice questions
-
What do we call melted rock while it is still underground?
Show answer
Magma — it becomes lava once it erupts to the surface.
-
What is the bowl-shaped opening at the top of a volcano called?
Show answer
The crater.
-
True or false: all volcanoes are constantly erupting.
Show answer
False — many are dormant (sleeping) or extinct.
Parent tip: The baking-soda volcano is a classic for a reason — but ask "what is different about a real eruption?" afterward to push past the fizz.
