Upon arrival, the students were divided into smaller working groups so that they could visit all the individual seminars in turn. Each topic was assigned to one lecturer who presented it both theoretically and practically.
The first station was photo editing on the computer. The teacher introduced the students to different image formats, with emphasis on the formats used for saving photos. The basic concepts of photography were discussed - shutter speed, aperture, depth of field, shooting modes, sensor size. Different graphic editors of raster images and their possibilities of use were also presented. In the practical part, students tried to adjust brightness, contrast and colour saturation, remove an object from a photograph and insert another one.
Another site was grinding and cutting minerals. The aim was to point out the different density and hardness of different working materials according to the principles of Mohs hardness scale. Each pupil could also try polishing on a polishing machine.
The third thematic area was electricity. Through modern teaching panels, pupils were introduced to the basic knowledge of electricity and tried to assemble different parts of the electricity system using modules. Using software, they then simulated and measured various operating conditions.
The last stop was the PASCO measuring system. The students first got acquainted with the system, including the software for measuring with it. This was followed by the theory of gravitational acceleration and acceleration on an inclined plane. Next, the pupils attempted to estimate the value of the acceleration due to gravity using the PASCO trolley - based on measurements of the acceleration of the PASCO trolley on different inclined planes. Finally, they compared their own measured value with the actual value of the acceleration due to gravity.
