In the context of this intervention students are firstly introduced to the main constituents of the weather in a region (temperature, sun time per day, waterfall, wind intensity, humidity, etc) by the science teacher. Then, together with the collaborating teachers discuss the proposed project and agree on the ways It will be implemented. In the next stage they visit the local weather station to meet the agent of NMS together with the Science and IT teachers, in order to learn about the measurement of the weather phenomena and the different types of data that the HNM Service collects on weather and the ways to locate and acquire them. In the next phase the students meet with a representative of from the central offices of the HNMS and the Local Office of Civil Protection Service to learn about the flow of weather data and their interpretation and storing from the Civil Protection context also and together with the 3 teachers discuss and agree on the data that will be sent from the Civil Protection Service database. Following that they work with the maths teacher and the IT teacher based on the sample data received and the data from the online database of the website of the HNMS Service on the ways to collect the full dataset (database of HNMS service querying and sent data from the Civil Protection office transformation, storing) and the mathematical calculations that will be made. Then students work on the data calculations and on the modelling of the weather in their city and the selected other city. Following that with the science teacher they discuss the results and formulate the final deductions and model. Then they work with the IT and Science teachers on the final presentations. The project is completed with the presentations of the findings from the two teams.
