Lesson notes

Learning Objectives

Indicator: 1.2.1.LI.1 - Discuss the thermometric substances and properties and their associated characteristics.

By the end of the lesson, learners can:

Define thermometric substance and state at least three examples with their thermometric properties.
Explain the relationship between a thermometric property and temperature measurement.
Describe the characteristics of a good thermometric substance used in thermometer construction.
Demonstrate through practical observation how different thermometric substances respond to changes in temperature.
Justify the choice of a particular thermometric substance for a given thermometer design.

Exemplars (from the NaCCA curriculum)

Explain thermometric substances and their associated characteristics. Experiential and Collaborative learning.
- Learners recall previous knowledge on heat and temperature.
- Learners in mixed-ability groups of 5, record their observations as one student places the finger in cold water then in warm water.
- Learners using a thermometer gun or liquid in glass thermometer measure the degree of hotness or coldness of the two substances.
- Learners discuss their observations and give reasons for their observations.
- Learners relate their reasons to the properties and characteristics of thermometric substances.
- Learners identify the various types of thermometric substances.
Ensure that the teaching materials, examples, and illustrations reflect diverse perspectives.
