Description of the activity

During the 4th teachers meeting in a LIVE event (video conference) on 18 February(participated 4 teachers from Petroupoli-Greece, Avila-Spain, Fregenal de la Sierra-Spain and Sfax-Tunisia) it was scheduled the way that the international teams would be created (DICE project on micro:bit) and the tasks for these teams. Team 2 would record the data and would analyse the data of the recorded temperatures according to the procedure that was agreed by the teachers: measurements would be made during the first 15 days of March (Sfax had problems with these dates as schools in Tunisia were closed but we agreed on this dates as Spain had Easter vacations in end of march and Greece had Easter vacation just after Spain). We had agreed to gave the micro:bit-thermometer (shared uploaded code for all partners) to our students at home for a few days and change the student if possible so that more have the opportunity to take part in the activity. We had also agreed students to make measurements twice a day, at 08:00 and at 23:00. Petroupoli had started measurements with Eleftheria at 28 February and Eleftheria gave her data and gave the circuit to Lito at 5 March. Lito had measured till schools lockdown at 11 march but she had met the teacher after the schools re-opening, in 21 May. Fregenal de la Sierra, had offered micro:bits to 3 different students and had the opportunity to make better recordings and getting average of the students' data. We had agreed that the students in Fregenal would not analyse the data as they were too young for this task.

DISCUSSION in class and Conclusions

A) Lito: We test 2 differenent micro:bits and we see that they shaw a different temperature

Sofia: We need a reliable instrument to compare and adjust what we see on the micro:bit

Teacher: Data from the micro:bit are about the temperature on "board" and not on the environment. We need to adjust-calibrate the measurements we get

B) Sofia: we should know what time to measure according to the official data. We have not measured at the same time and it is difficult to compare. 

C) Christos: 

The Spanish students have worked better than us as they have used 3 micro:bits they have measured at the same time and they have calculated the average

D) Lito: Fregenal de la Sierra and Petroupoli seem to have quite similar climate

Teacher

We have started the measurements when OCVID19 was already here. We had not the chance to correct the procedure. Data analysis needs much time and it is very difficult and we had not managed to have some advice by an expert (meteorologist as we had the idea to do). We had chosen the right source for gathering all partners' recorded data -to share a common ground of comparisons- and also the greek site was a very good source as the data offered were from a place very close to our town.

If we decide to repeat the procedure next year then

a) we must use two micro:bits

b) we must calibrate them properly

c) we must set a measuring protocol. Important points to take care: place and time for collecting the data, operational time of the circuit not to have a "warm" board, a pre-selected official database, an invitation to an expert to have some advice before we start

So...this activity was a learning experience, though we have not managed to follow the exact scheduled process
