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.1 - Explain the kinetic theory of matter and apply it to distinguish between the properties of solids, liquids and gases.

Suggested placement

Semester 1, Week 18 (Week 18 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 and recall chemical bonding and states of matter from JHS curriculum.
- With the aid of simulation or videos or charts, investigate/illustrate the behaviour of the particles in solids, liquids and gases and record the observations.
- In groups of three, draw sketches to represent the arrangement of particles in solid, liquid and gaseous substances.
- Research about the kinetic theory of matter and use it to explain the properties which distinguish gases from liquids and solids under the following headings: a) Volume b) Shape c) Compressibility d) Density e) Spacing of particles f) Motion of particles g) Force of attraction between particles h) Arrangement of particles
- In mixed-ability groups or in pairs use the kinetic theory to explain the various change of state processes.
Experiential Learning:
- Perform experiments to determine the melting point of a solid.
- Perform experiment to determine the boiling point of a liquid.
