Anàlisi del nivell d'autoestima i de violència a la nostra escola
En motiu del dia de la no-violència i la Pau a les escoles, el 30 de gener, hem analitzat les nostres pròpies respostes a dos tests oficials, un d'avaluació de l'autoestima i un de la violència escolar.
L'anàlisis s'ha fet dins el projecte 'Estadística i Consciència Social' de l'assignatura de matemàtiques. A més, els resultats també formen part del projecte Europe on 7 Hills (Erasmus+)
L'alumnat ha preparat un informe amb les conclusions més rellevants.
Esperem que us agradi!

But, thanks to our tenacity, creativity and teamwork, we solve it!

The cause was a too high fan velocity that could be decreased providing less power (wee needed an AC/DC adjustable power supply). 7.5 volts worked perfectly!


And this is our final magneti…
