Kids of primary school will be given by their teachers the theme Organic waste. The teachers will have to inform the kids about the broad content of the term. They will have to explain why some of our waste are considered organic and why this kind of material is not in essence or should not be considered as a waste material. They will explain the procedure of composting organic material and the use of it for the improvement of our soil and the need for the avoidance of desertification. The theory will become practice with easy games of sorting out which material goes in the category and which is not. The kids will draw in printed by the school, easy prints, some of the materials that they think should go in the appropriate bin. etc. All these will have to be revised in the case of a complete lock-down due to covid-19 precautions.
