Gr. 9 – Science Applied – Strand 3

Chemistry (Exploring Matter)

Grade 9 (Applied) Overall Expectations:

1 – Analyse the impact of human activity on terrestrial or aquatic ecosystems, and assess the effectiveness of selected initiatives related to environmental sustainability

2 – Investigate, through inquiry, physical and chemical properties of common elements and simple compounds.

  • Use an inquiry process to identify the physical and chemical properties of common elements and simple common compounds, including gaseous substances (e.g., sulfur is a yellow solid; sodium chloride is water soluble; nitrogen gas is colourless, odourless, and very unreactive) [PR, AI].
  • Plan and conduct an investigation to compare and contrast characteristic physical properties of metals with those of non-metals (e.g., most metals are lustrous or shiny and are good conductors of heat; most non‑metals in solid form are brittle and are not good conductors of heat) [IP, PR, AI].
  • Conduct chemical tests to identify common gases (e.g., oxygen, hydrogen, carbon dioxide) on the basis of their chemical properties, and record observations [PR, AI, C].

3 – Demonstrate an understanding of the properties of common elements and simple compounds, and general features of the organization of the periodic table.
