Grade 9 Unit Overview (Alberta)
Different materials have different properties. The ability to distinguish between different substances and make sense of their properties, interactions and changes requires development of ideas about chemical substance. In this unit, students are introduced to the formal study of chemical substances through laboratory investigations and introductory studies of chemical theory. In the laboratory, students observe and compare chemical substances and, with guidance on safety, investigate the properties of materials and the ways they interact. In conjunction with these studies, students are introduced to ideas about elements and compounds, and corresponding structural ideas of atoms and molecules. Theoretical ideas are introduced as means for explaining, interpreting and extending their laboratory findings; and include a general introduction to the periodic table, chemical nomenclature and simplified ways of representing chemical reactions.
