The new ELI today is an extension of one we published many years ago, 'See how they run; investigate why some lavas flow further and more quickly than others'.
This activity involves an investigation into some of the factors which can affect the viscosity of lavas. The two activities included involve varying the temperature and composition of the 'lava' using treacle and honey.
Other related activities can be found in our Natural Hazards category - Volcanoes.
