We present some reflections about using cartoons as an innovative tool for teaching science, as well as for contributing to the practice by teacher researchers. These ideas were part of the results obtained in the seminar Cartoons, offered by the research group “learning and teaching physics”, into the 1st festival of art and science for coexistence, held in Maloka, Bogota, 2009. We analyzed the particular case for physics teaching based on cartoons, thinking about what that's means in didactic of physics.
