Children must receive scientific facts also. Science is a knowledge which elucidates the real matters, with proofs, regarding the nature that we exist in and the society that we live in.
One need not learn all the aspects of science related to every Nature. Every person need not thoroughly learn the medical sciences. It would suffice if they are familiar with the routine hygiene principles to practice on a daily basis. When aliments descend on people, the clinicians will take care of the diseases. Every person need not have the medical knowledge as much as clinicians do. This also applies to the other natural sciences.
However, this is not the case with the science that teaches us regarding the society that we live in. We are human beings, not animals. The animals are born and are dead the same way as they were born. They do not need any kind of science or knowledge. The human being, however, must know about human relations. The economic science explains relations. The Economic science explains relations among humans and their ways of living. This is the science that portrays the lives of yesterday, today and tomorrow.
