Colleagues from the Optics Institute and members of the IOSA Chapter have videotaped the successful workshop entitled "Discovering light".
This new online format allows the experiments to be viewed from the homes of whoever wants and can repeat them, in addition to the fact that the workshop can be requested in person through the CiudadCiencia project.

Would you like to know more about optics? Now you can understand many of its phenomena easily with the videos of the experiments in the 'Discovering light' workshop.
These experiments can be carried out from home accompanied by the indications of the 7 available videos.

To do the experiments at home you need very simple materials that are easy to find in the classroom or at home. One of them teaches how to make objects disappear in water and another explains why some materials glow in the dark. In another video they will tell us how to build a hologram and we will be able to understand what are the phenomena of refraction and chemiluminescence, or how a microscope works.

For more information, go to the web of the workshop in CiudadCiencia




Invisible balls: How is it possible to make an object disappear in water? In this experiment, the participants will succeed and learn the phenomenon of refraction.


Refraction: Why does a pencil seem to curve when we put it in a glass of water? Participants will understand what the phenomenon of refraction consists of.


Homemade hologram: With the help of simple materials, the participants will be amazed by the recreation of three-dimensional images using, for example, a mobile phone or a tablet. To do this, it is necessary to download the pseudo-hologram template.


Fluorescent spinach: Did you know that there are animals, plants, and objects that can glow in the dark? In this experiment, participants will understand what fluorescence is and how certain living things, such as spinach, absorb ultraviolet light.


The basic properties of light: How many optical elements do you know? Participants will discover different lenses (convergent and divergent), mirrors, sheets or splitters of light beams. They will observe how the sense of light changes as it passes through these elements and they will understand concepts such as refraction or reflection.


Home microscope: In a very simple and enjoyable way, it will be explained how to create a home microscope to be able to see microscopic organisms, such as those found in a drop of water in a puddle.


Fluorescence applications: Fluorescence and phosphorescence star in this experiment through different materials that glow in the dark. To find out, participants must carry out this experiment in which they will also put themselves in the shoes of a scientific police officer to understand the phenomenon of chemiluminescence.
