Matter and Its Properties (1.1)

Content standard

1.1.1.CS.3 - Demonstrate understanding of the use of the kinetic theory of matter to explain the behaviour of solids, liquids and gases under different conditions and describe the laboratory preparation of gases as well as their uses in everyday life. 1.1.1.LO.1 Use the knowledge and understanding of the scientific practices in Chemistry to explain the structure of the atom as well as the stability of its nucleus. 1.1.1.LO.2 Use the mole concept to determine the amount and quantity of various substances involved in chemical reactions. 1.1.1.LO.3 Write mole ratios for chemical equations and apply it in quantitative analysis. 1.1.1.LO.4 Use the kinetic theory of matter to explain the behaviour of solids, liquids and gases under different conditions and describe the laboratory preparation of gases as well as their uses in everyday life.

Indicator

1.1.1.LI.4 - Write the ideal gas equation and apply it in simple calculations using the different numerical values of R and units of pressure and volume.

Suggested placement

Semester 2, Week 1 (Week 21 of the year)

Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Collaborative Learning:
- Review previous knowledge on the Boyle's law, Charles' law and Avogadro's law.
- Work in groups to show how the laws above can be combined to give the ideal gas law.
- Discuss each of the variables in the ideal gas Law.
Problem Solving Approach: Practice using the ideal gas equation (PV = nRT) in solving theoretical tasks including determination of molar mass.
In small mixed-ability groups: Use ideal gas equation to determine the molar mass of different gases.
