In today's class we have started exposing, my group, the project that we have carried out during all this time. Finally we did it about the use of plastics in Spanish supermarkets. The structure of the work was as follows: - Talk about supermarkets in Spain - Talk about supermarkets in other countries - Talk about possible changes within supermarkets in Spain Then we have had a small debate. To do this, we asked our colleagues to participate by giving their opinion, indicating whether they thought that at any time the total disappearance of plastic in supermarkets would be possible. Then Irene introduced us to inquiry teaching and asked us to read a document for the next day.
