Summary:Demonstrate how the proportions of oxygen in ice and deep-sea cores can be used to interpret past Earth temperatures with ‘The oxygen isotope sweet simulation' Earthlearningidea. This uses coloured sweets (e.g. Midget Gems) which have been divided up into different colours. One set of pale-coloured sweets is put together with one set of darker coloured sweets to represent oxygen isotopes:.
