During the "Colourful chemistry" workshop, the children observed how the colours of liquids change depending on the added indicator and the reaction of the solution. Pupils investigated and analysed how the colours of natural dyes contained in turmeric, cabbage and flowers can change. They analysed how they could be used to study the contamination of soil and rainfall and in this way assess the state of the environment.
Some funny exercises of IT were also designed to deepen the knowledge of students on envirnomental issues.
