The present paper describes an experience of science theatre addressed to children of primary and secondary school, with the main purpose of making them acquainted with a topic, the interior of the Earth, largely underestimated in compulsory school curricula worldwide. A not less important task was to encourage a positive attitude towards natural hazards that are here presented as an expression of our planet vitality. We conducted the experience with the help of a theatrical company specialized in shows for children, trying to merge scientific accuracy, entertainment and ethical issues. Several performances have been reiterated in different context, giving us the opportunity of conducting a preliminary survey with a public of different ages, skills and expectations. Results suggest that science theatre, while relying on creativity and emotional learning has the potential to raise children interest on the process of making science, on natural phenomena and may trigger a positive attitude on natural disasters reduction best practices.
