Curriculum details

Strand

Physical Chemistry (Strand 1)

Sub-strand

Matter and Its Properties (1.1)

Content standard

2.1.1.CS.1 - Demonstrate knowledge and understanding that energy changes occur in chemical reactions as a result of reorganization of atoms at different rates. 2.1.1.LO.1 Describe the different energy changes that occur as a result of reorganization of atoms. 3 Gender Equality and Social Inclusion 4 Socio-Emotional Learning 2.1.1.LO.2 Use the concept of chemical kinetics to explain that chemical reactions proceed at different rates depending on their conditions and design experiment to investigate these conditions.

Indicator

2.1.1.LI.5 - Explain the term rate of reaction and describe the suitable experimental procedures for measuring rates of reactions.

Suggested placement

Semester 1, Week 5 (Week 5 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 Approach: Using think-pair-share approach, discuss and explain the term rate of reaction and determine ways of expressing the rate (initial rate, average rate and instantaneous rate).
Inquiry-Based Approach: In small mixed-ability group, discuss suitable methods or use virtual laboratory to determine suitable procedures for measuring rates of reaction. Examples colour change, changes in volume of gas evolved, formation of precipitate, change in mass, appearance, and disappearance of product etc.
Teaching and Learning Materials:
- * Worksheets: for drawing and labelling enthalpy profile diagram. * Worksheets for supporting calculation of standard enthalpy changes. * Worksheets with task on applying Hess' law to calculate enthalpy of reaction. * Calculator * Hot water * Hydrochloric acid * Sodium hydroxide pellets * Thermometer * Copper sulphate * Zinc powder * Virtual lab on calorimetry * Use of gas syringe * Chemical balance * Calcium chloride
- * Probe
- Beakers (100ml and 400ml)
- Ammonium chloride * Calorimetry setup * Conical flask * Beakers * Marble chips * Hydrochloric acids * Kits for sulphur-clock experiment * Kits for investigating effect of of H O 2 2 * Graph sheets
