CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION 

Heat is a form of energy. In everyday language, heat and temperature are often used as if they are the same thing. They are not. When a pot of water is heated it gains energy and becomes hotter. Its temperature goes up. Heat is the cause, a rise in temperature is the effect.

When a substance is hot, the temperature is high and when the substance is less hot (cold), the temperature is lower.

Temperature can be measured with a thermometer.

DIFFERENCES BETWEEN HEAT AND TEMPERATURE 

MEANING OF HEAT 

Heat is a form of energy that increases the level of hotness of a body.

 

MEANING OF TEMPERATURE 

Temperature is the degree. Of hotness (warmness) or coldness (coolness) of the body – water, iron, food, etc. . That’s, how hot (hot) or cold (cool) a thing (water, human body, etc.) is.

 MEANING OF THERMOMETER 

Thermometer is an device used for measuring temperature of a body. For example, how hot or cold is water, food, iron, human body, etc.

TYPES OF THERMOMETER 

1. Clinical or Medical thermometers – It is used to measure body temperature.

2. Laboratory thermometers – It is used to measure the temperature of an experiment.

3. Infrared ear thermometers – It is used to measure the temperature in the ear.

4. Infrared thermometer – It is used to measure the temperature of a surface. For example, forehead.

5. Mercury thermometers

6. Digit or analogue thermometer – Thermometers are either in digital and analogue mode.

LESSON TWO – MEASUREMENTS OF A BODY TEMPERATURE – PRACTICAL 

Using hot and cold water.

Teacher’s remark – Makes the pupils take note of reading in degree Celsius or Fahrenheit if the available thermometer is both degrees. 

LESSON THREE – WEEKLY ASSESSMENTS 

As stated in performance objectives or lesson lesson evaluation. 

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Guides pupils discussion of differences between Heat and Temperature.

Pupil’s Activities – State the different between heat and temperature.

3. Provides the pupils with different types of thermometers.

4. Uses charts to guide the pupils to identify different types of thermometers.

Pupil’s Activities – Handle and examine thermometer.

5. Demonstrate the correct method of using the thermometers to measure the temperature of objects.

Pupil’s Activities – Practice, measure and record accurately the temperature of things e.g. hot water, their bodies, etc,

CONCLUSION

• To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

• Next Lesson – Heat and Temperature II – Units and Symbols of Temperature Scale (Primary 5)

LESSON EVALUATION 

Pupils to:

1. state the differences between heat and temperature.

2. name any three types of thermometers.
