This preliminary study seeks to explore whether wonder-based reflections are sources of inspiration for future teachers of science. What experiences have brought them personally a sense of wonder and when, if at all, do they employ scientific explanations of those events? In all 140 pre-service primary teachers, when questioned, described 240 separate events or occasions in which they had participated or observed that evoked a heightened sense of wonder. Three different types of wonder described all the events cited: physical, personal and metaphysical wonder.
