Query: La optica de imagenes en la extension universitaria de Unicamp   The physics teaching particularly the optics teaching always have faced
motivational problems, mostly due to the loss of the link between the social
practice and the daily life of the student. Moreover, the laboratory practices
have lost space in high school attributable to a lack of resources or caused by
the fact that the main purpose of the high school is being no more than the
access to the University. This work shows how an extension activity called
"Holographic Exhibit" tries to motivate high school students by means of
experimentation, observation and the application of physics concepts in daily
life, awakening their interests to the general physics.
  La ensenanza de la fisica y en particular de la optica siempre ha enfrentado
problemas de aspecto motivacional principalmente por la perdida del vinculo con
la practica social y con la vida cotidiana del estudiante. Ademas, las
practicas de laboratorio han perdido mucho espacio en la ensenanza media por
carencias de las escuelas o debido a que tiene apenas como objeto el examen de
ingreso a la universidad. El objetivo de este trabajo es mostrar como una
actividad de extensi\'on universitaria llamada 'Exposicion de Holografia'
intenta motivar a estudiantes de ense\~nanza media a traves de la
experimentacion, observacion y aplicacion de conceptos fisicos en la vida
cotidiana, despertando sus intereses por la f\'isica general.
