Head of Natural Sciences: Teachers: Natural Sciences is a subject that essentially prepares learners to succeed in Physical Sciences and/or Life Sciences. This means that the content in the subject is always going to be interesting! In grade 8 the content covers topics including environmental issues, introductions to chemistry, electricity, visible light and the structures in the solar system and beyond. In grade 9 the content covers topics including the human body systems, chemical reactions, forces, the Earth as a system and the birth, life and death of stars. Naturally, these topics encourage learners to ask questions and think critically – sometimes to the disadvantage to the teacher (thanks Google…).
