Lesson notes

Learning Objectives

Indicator: B5.4.1.2.1 - Show the relationship between heat and temperature

By the end of the lesson, learners can:

Explain in their own words that heat is a form of energy which flows from a hotter object to a colder object, while temperature is a measure of how hot or cold an object is.
Predict and observe what happens to the temperature of a substance when heat is gained (e.g. placing objects in the sun) or lost (e.g. placing objects in water or a fridge).
Demonstrate through a hands-on activity that touching objects after heating or cooling them can show changes in temperature.
State that when heat is gained, temperature increases, and when heat is lost, temperature decreases.
Use the terms “heat” and “temperature” correctly in discussions, showing awareness that they are related but different concepts.

Exemplars (from the NaCCA curriculum)

- Review previous lesson on temperature with learners.
- In a group discussion, learners find out what will happen when heat is applied to a substance or lost from a substance, e.g. when a substance is placed in the sun for a while or when a substance is put in a fridge.
- Learners undertake an activity of placing objects such as metal plates, pieces of stone in the sun.
- Learners initially touch the objects to feel their degree of warmness before they are put in the sun.
- After 20 minutes, learners touch the objects again and feel the difference in temperature.
- Learners should then place the stones or metals in a bowl of water and afterwards, touch again to determine whether they become hotter or colder.
- Elaborate on learners' ideas, emphasising heat as the factor that changes temperature.
- Summarise lesson by explaining to learners that when heat is lost, temperature reduces, when heat is gained, temperature increases.
