'Bubble-mania; the bubbling clues to magma viscosity and eruptions' is this week's Earthlearningidea. After trying the activity, ask the pupils:-
• How were the ‘eruptions’ different?
• How were the bubbles different?
• What caused the differences?
• Some volcanoes have magmas that are ‘runny’ (like the soft drink) and some have much more viscous magmas (like the other liquid) – how might these volcanoes erupt differently?
• Which sort of eruption would you most like to see – one with low viscosity (runny) magma, like the soft drink, or one with high viscosity (thick) magma like the viscous liquid?
This is one of many ELIs about volcanoes and volcanic eruptions - click here to find them all.

Just want to say how much I like this particular ELI. Can’t wait to see others try it!
PS As I have commented previously, I think that ELIs are doing a fantastic job of making practical Earth Science accessible to all - right around the world.
