'Take a 'Chance' on the volcano erupting' is our latest Earth
Learning Idea. In this activity, pupils measure the force
required to burst a party popper and use this as an analogy for
the prediction of volcanic eruptions. A series of possible
events in the build up of a volcanic eruption is given on
'Chance' cards. These are selected at random and the
instructions given on the card should be followed until the
party popper 'erupts'. Through this activity, pupils will
discover many of the factors which are associated with the build
up to a volcanic eruption. These include seismic activity,
changes in gas emissions, swelling of the volcano's surface, and
minor eruptions of tephra (solid particles of congealed lava, in
the form of ash or larger fragments). This is one of many ELI
activities associated with volcanic eruptions. Try the related
ideas which will be shown on the home page for the next two
weeks.
