Energy is a central, cross-cutting concept in science, but its abstract nature poses challenges for learners. Metaphor has been recognized as a productive resource used by students, teachers, and scientists to understand and communicate about energy. While much research has focused on metaphors about energy expressed in learners’ speech, we know less about the range of ways learners use gesture to evoke metaphors about energy. In particular, the metaphor energy as substance has been found to be useful for conceptualizing various features of energy. Using a microethnographic approach, we demonstrate how students in an introductory algebra- based university physics course use gesture in three different ways to evoke substance-like metaphors that offer valuable affordances for sensemaking about energy: These include (1) container metaphor gestures, (2) stimulus metaphor gestures, and (3) accounting metaphor gestures. Implications for learning and teaching about energy are discussed.
