In case the hon member is like me - these grades also confuse me - Grade 4 is Standard 2 according to the old terms. This means that it is already at that early age. So, we are saying that between Standard 2 and Standard 9 minus two - Grade 7 - they will have learned that. [Laughter.]
Therefore, if we take those back to exactly the age that we were being taught these things, you will see that we are teaching them at the same age; it is just that we are using different terms for the grades. It sounds later, but it is actually earlier. It is Standard 2, so I guess it is early enough to expose them to these issues. As I have said, we have also changed the way we name subjects.
Perhaps what you were calling Environmental Studies, being older than you, we called something else in my time. Now you might find that the subject that you named, calling it in Afrikaans, is one of the subjects here; either it is Natural Sciences or Social Sciences. So, these might be terms that we are talking about.
The fact of the matter is that we are indeed trying to spread as much as possible across the different subjects at a lower phase. As the member has said, at a senior phase, where we now include the concepts as part of Physical Sciences, where we are now looking at the scientific part of it, it is in Grades 10 and 12. Grade 10 is Form 3 and Grade 12 is Form 5.
That is where we go deeper. So it is exactly at the same age, there is just a difference in how we name the grades and subjects. But we agree with you.
