Since the students have worked on the WERWORLD Teaching Guide activity “Making compost”, they have been able to learn and know the different types of elements that are used to make compost. Through this game, they will be able to both learn more elements and check if they have learned correctly. The objective of this game is to learn more types of elements and, especially, foods that are used to make compost, as well as challenge ourselves to be able to differentiate the elements that work from those that do not.
