UNIVERSUM, the science museum of the National Autonomous University of Mexico, was designed to allow for various degrees of involvement depending on the interests, level, and different learning styles of the visitors. In order to do so, many front‐end evaluation studies on a wide variety of subjects were performed with high school and first year university students (our target audience). As a result, several sections, such as the ones that deal with physics, offer students an opportunity to update their knowledge, carry out experiments, and have a good time in a place tailored for their needs. The relationship between formal and informal education in a place such as this one is discussed.
