Member, I did indicate that these issues are dealt with in Natural Science and Social Science in the lower grades, where there is no choice of subject. So every learner will have been exposed to them. It is only in Grades 10 and 11 where they are only found in Physical Science and Life Science.
Therefore, the basics will have been learned in the intermediate phase where every child will have been exposed to them. Only the deeper concepts are tackled under Physical Science, which are the mitigating factors. This is really not so much a civic education issue, but a deeper understanding of the physics around them that they are taught about in a later class. But all children will have been exposed to these issues in their intermediate phase.
