'Can we do That Again?' Engaging Learners and Developing Beyond the 'Wow' Factor in Science
Adding Mentos to an open bottle of Diet Coke can produce a fountain of liquid and froth extending several metres high. This activity can engage a wide audience of learners in a relevant and meaningful way, provide a model for creative science teaching, and help to develop learners’ attitudes towards school science as a subject. In this paper, the authors describe the use of this activity with primary-aged learners. Some challenges associated with the construction of the delivery mechanism for the Mentos are discussed, and ideas are provided for improving the performance of the fountain.
