The first meeting took place in Prague. The teachers met here for the first time, had the opportunity to get to know each other, establish contacts and discuss the implementation of the project. The meeting took place in Prague, so there was more time for work. The premises of the Tereza organization were used for the meeting, the teachers also visited the laboratories of the Vltava river basin and tried the measurements themselves. Colleagues from Latvia trained others in working with Pasco devices.
