Curriculum Expectations

Big Ideas

• Properties of gases can be described qualitatively and quantitatively, and can be predicted.
• Air quality can be affected by human activities and technology.
• People have a responsibility to protect the integrity of Earth's atmosphere.

Overall Expectations

• F1. analyse the cumulative effects of human activities and technologies on air quality, and describe some Canadian initiatives to reduce air pollution, including ways to reduce their own carbon footprint;
• F2. investigate gas laws that explain the behaviour of gases, and solve related problems;
• F3. demonstrate an understanding of the laws that explain the behaviour or gases.

Specific Expectations

• F1.1 analyse the effects of air quality on some technologies and human activities (e.g. smelting; driving gas-powered vehicles), including their own activities, and propose actions to reduce their carbon footprint
• F2.1 use appropriate terminology related to gases and atmospheric chemistry
• F2.2 determine, through inquiry, the quantitative and graphical relationships between the pressure, volume, and temperature of a gas
• F2.3 solve quantitative problems by performing calculations based on Boyle’s law, Charles’s law, Gay-Lussac’s law, the combined gas law, Dalton’s law of partial pressures, and the ideal gas law
• F2.4 use stoichiometry to solve problems related to chemical reactions involving gases (e.g., problems involving moles, number of atoms, number of molecules, mass, and volume)
• F2.5 determine, through inquiry, the molar volume or molar mass of a gas produced by a chemical reaction
• F3.2 describe the different states of matter, and explain their differences in terms of the forces between atoms, molecules, and ions
• F3.3 use the kinetic molecular theory to explain the properties and behaviour of gases in terms of types and degrees of molecular motion
• F3.4 describe, for an ideal gas, the quantitative relationships that exist between the variables of pressure, volume, temperature, and amount of substance
• F3.5 explain Dalton’s law of partial pressures, Boyle’s law, Charles’s law, Gay-Lussac’s law, the combined gas law, and the ideal gas law
