During one hour and a half we picked up all the garbage in our school.
It took us 2 days to sort out the garbage. We divided it according to its type and made a big exhibition at the school hall.
All students look at it. They were asked if the Garbage was theirs. "Este lixo é teu?"
New teams to clean the school have been made and this will happen on a week basis. Hopefully one day we will not need to clean our school!!
