Lesson notes

Learning Objectives

Indicator: B2.4.1.2.1 - Understand that objects become hot or cold through the loss or gain of heat

By the end of the lesson, learners can:

Describe, in their own words, what happens to an object when it gains heat or loses heat.
Demonstrate through practical activity that rubbing palms together, boiling water, and burning a candle produce heat.
Identify everyday situations where objects gain heat and where objects lose heat.
Plan and carry out a simple activity to make water either hot or cold, recording their observations.
Explain why a hot substance left to stand for some time becomes cooler.

Exemplars (from the NaCCA curriculum)

- Learners feel hot and cold substances and discuss their observations.
- In a practical activity, learners create heat by rubbing the palms, boiling water, burning candle, etc.
- Engage learners in an activity that makes things lose heat, e.g. adding cold water to hot water, leaving a hot substance to stand for some time, unplucking a hot electric iron, or a local box iron, putting a substance in a refrigerator etc.
- Provide learners with water and ask learners to plan how to make it hot or cold.
