Lesson notes
Learning Objectives
Indicator: 1.2.1.LI.3 - Describe the various temperature scales and the construction of their corresponding thermometers.
By the end of the lesson, learners can:
- Identify the Celsius, Kelvin, and Fahrenheit scales and state the fixed points (upper and lower) used to define each scale.
- Describe how a liquid-in-glass thermometer is constructed, including the choice of thermometric substance and the role of the capillary tube and bulb.
- Explain the construction and operating principle of a thermoelectric (thermocouple) thermometer and a resistance thermometer.
- Relate the reading of a thermoelectric or resistance thermometer to the Celsius scale using the upper and lower fixed points.
- Describe at least two practical advantages and two limitations of each thermometer type covered in the lesson.

Semester 1, Week 15
(Week 15 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.
- Curriculum reference
- NaCCA curriculum document, p. 47
Exemplars (from the NaCCA curriculum)
Talk for learning: Let learners watch a video/simulation on the operating principle of thermometers such as the thermoelectric, resistance and relate them to the Celsius scale using the exemplar for the preceding indicator. Ensure that the teaching materials, examples, and illustrations reflect diverse perspectives. Assessment (1.2.1.AS.3). The document marks no depth-of-knowledge level for this indicator.
