Environments may be categorised in two broad groupings; natural environments and human environments.

Science education enhances children's knowledge and understanding of themselves and the world in which they live.

Historical education enables children to investigate and examine critically events in their own immediate past, the past of their families, local communities and the histories of people in Ireland and other parts of the world.

In geographical education, children explore and learn about features in natural and human environments, especially those in the immediate locality.

A key characteristic of learning within S.E.S.E. is the involvement of the child in active exploration and investigation of these environments.
