Taller d'energies renovables

El passat 9 d'abril els alumnes del projecte Comenius van realitzar un taller d'energies renovables organitzat per l'Àrea Metropolitana de Barcelona. Aquí us presentem els resums que alguns alumnes van fer sobre aquesta activitat: 


LA NOSTRE EXPERENCIES AMB LES ENERGIES RENOVABLES GRÀCIES AL COMENIUS

Avui em iniciat un taller sobre les energies renovables, unes de les activitats del programa Comènius. La Susana, la encarregada del taller, ens ha presentat en forma de dossier el temari de les energies renovables. Ens ha portat al pati de l`escola per poder provar algunes fonts d`energia renovables (algunes, fins i tot, casolanes). Després ens hem distribuït en diversos grups, i a cada  una se li ha assignat una maqueta corresponent.



Primer em identificat les diferents parts dels captadors d’energia de les maquetes,i hem pogut observar que aquestes fonts produeixen electricitat molt ràpidament ( menys la solar tèrmica que  no produeix electricitat). Hem respòs un qüestionari sobre la nostre energia i cadascú ha après suficient d’aquesta energia com per després exposar la seva font/ maqueta als companys. Ha sigut una experiència molt bona per relacionar-nos més amb les energies renovables i observar que produeixen més energia del que pensàvem i tots hem observat la gran quantitat d’estalvi de Co2 que suposaria. IT’S EASY TO HELP THE ENVIROMENT !


COMENIUS: RENEWABLE ENERGIES WORKSHOP


Today, 9th April, before the breaktime, we’ve done a workshop about renewable energies. This workshop was divided in four different parts, and we’ve worked on the part of eolic energy. In this part we have done many different activities about our energy, with a little turbine. Firstly, we have identified the parts of the turbine. Secondly, we have started to learn about the wind rose. We had to find all the types of winds and put them in the correct cardinal point. After that, we have measured the wind speed, generated by a ban because there wasn‘t any wind, with an anemometer. Finally, we have done the activities that the worksheet proposed. Then we had to explain it in front of the other Comenius’ students explaining them what  we had done. The other parts of the workshop were: the two types of solar energy and the hydroelectric energy.

RENEWABLE ENERGIES EXPERIENCE: THERMAL SOLAR ENERGY
 

Today we’ve made a workshop about renewable energies. There were four tables which were full of homemade scientific objects with some examples of how easy it is to use the renewable energies at home. We have been divided in four groups of four or five each .
Our group worked over the thermal solar energy, and we’ve seen a solar captor which worked with a plastic tube which had water inside, and it made a closed circuit where water got warmer at a time.
After a while, about fifteen minutes later, we checked the temperature inside the box, and we notice that it was  78.4 Celsius degrees. After more twenty minutes, it was ninety-four Celsius degrees.
The water came into the box through a tube, and it went up through  a s-shaped form, to try to take advantage of the maximum distance of the tube. Then, it wents out of the box through a tube which drove it to a water container , where it got cold and it restarted the circuit.
We’ve had a really great  time this morning!!!
