Soil chemistry

Soil is present in the lives of all human beings and we depend on it for our survival. In view of this, the general aim of this work was to draw up proposals for sequences of lessons that could be taught by teachers of the Chemistry curriculum component to students in the first year of secondary school, with the central theme being 'soils' and specifically to show the importance of handling soil correctly; to identify the Chemistry content that can be worked on in secondary school.
