Given the progressive loss of influence for the school relative to television in youngsters' everyday lives, this article describes the procedure and the results of including cartoons in the physics curriculum in secondary education. Work was carried out intensively with a small group of pupils and sporadically with a larger group. In the first case, cartoons were used for identifying and discussing fictitious phenomena, problem-solving, and assessment of the learning. In the second case, for identifying and discussing fictitious phenomena, a quasi-experimental research design was followed. The results back the use of this didactic tool as an element for motivating and invigorating the classroom, for identifying the pupils' alternative ideas and the assessment of their learning, as well as for a more critical way of watching television.
