CIBIT science club at school during the science week 2020
The students remembered what light is and how we perceive color, recalling several concepts such as radiation, electromagnetic spectrum, wavelength, frequency, light beam, color blindness and vision. It was explained that the perception of visual reality, results from the interaction between the brain and the organs of vision, where the experience of the context has a fundamental role.
Images and videos were used, with interactive exercises, which demonstrated how our brain reacts to what it perceives as a “reality built by experiencing the world”.
Based on the experiences perceived in daily life, our brain creates "event patterns". In this way an illusionist directs our visual attention to a place or object, confusing our brain and generating an illusion.
This was a successful colaboration between CIBIT/ICNAS researchers and the Martim de Freitas School financed by the POCH.
