Grade 9 Natural Science
4 Seasons
Science is a discipline that sustains enjoyment and curiosity about the world and natural phenomena. It deals a lot with links to related topics to form understanding of nature and connectedness in Natural Sciences.
Natural Sciences lays the basis of further studies in more specific science disciplines, such as Life Sciences, Physical Sciences, Earth Sciences or Agricultural Sciences. It prepares learners for active participation in a democratic society that values human rights and promotes responsibility towards the environment.
Natural Sciences can also prepare learners for economic activity and self-expression through the knowledge strands used to organise the content such as Life and Living, Matter and Materials, Energy and Change and Planet Earth and Beyond.
