THIRD TERM

WEEK 7

PRIMARY 5

THEME – YOU AND ENERGY 

PREVIOUS LESSON – Meaning and Importance of Energy Conversion (Primary 5)

 

TOPIC – MEANING OF HEAT AND TEMPERATURE 

 

LEARNING AREA 

1. Introductory Activities

2. Meaning of Heat

3. Meaning of Temperature

4. Different Between Heat and Temperature

5. Types of Thermometer

6. Taking measurement with clinical thermometer

7. Lesson Evaluation and Weekly Assessment (Test)

 

PERFORMANCE OBJECTIVES 

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. distinguish between heat and temperature.

2. identify and name different types of thermometers

3. use the thermometer to measure the temperature of objects accurately.

 

RATIONALE 

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.

The concept of heat and temperature will enable the pupils to understand and state the difference between heat and temperature.

 

ENTRY BEHAVIOUR

The pupils can identify changing in weather – Hot (warm) or Cold (cool).

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. A chart showing different thermometers

 

 

2. Different thermometers

4. Flask of hot water.

5. Some ice water.

 

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

WRITING INSTRUCTION 

Copy as I write or draw as I write. This instruction should be given when you need the pupils to write or draw.

 

CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTORY ACTIVITIES 

ACTIVITY 1

Teacher’s Activities – Ask the pupils,

1. What happens when you stay long under the sun?

2. What do you feel in a room where there is no fan or A/C?

3. What do you feel in the kitchen when you are cooking?

Pupil’s Activities – Feel heat under the sun. Feel heat in a room without fan. Feel heat in the kitchen.

Teacher’s Remark – Heat increases the level of hotness of a body. There are times when our body are cold or hot.

Ask the pupils, what happens when we are hot? Expected responses – shivering. What happens when we are hot? Expected responses – fever. Correct. Discuss the concept of heat and temperature with them and their meaning on the board.

 

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.

 

 ACTIVITY 2 

Teacher’s Activities – Display charts showing,

1. A mother using her hand to check the temperature of her child.

2. A nurse using thermometer to check the temperature of her patient.

Ask the pupils to study the charts and describe their observations.

Pupil’s Activities – Participate actively in the chart studies.

Teacher’s Remark – Listen to the pupils responses and comments. The nurse is using a device called thermometer to check temperature. Ask the pupils, what is thermometer? Discuss different types of thermometer and write on the board.

 

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.

 

QUICK EVALUATION

Ask the pupils,

1. What is  the different between heat and temperature?

2. Demonstrate how your parent check your body’s temperature.

3. Demonstrate how the nurse check body’s temperature at the hospital.

4. What is thermometer?

5. Mention 3 types of thermometer.

 

ASSIGNMENT 

Get ready for an excursion.

 

LESSON 2 – MEASUREMENTS OF A BODY TEMPERATURE – PRACTICAL 

Organize an excursion to the nearest hospital for random check of body’s temperature.

 

LESSON 3 – MANUAL MEASUREMENT OF TEMPERATURE (THE BOILING WATER) 

Guided Instructions

1. Put some water in a pot and heat it gently.

2. Put your hand in it after one minute and tell how hot or cold it is.

3. Do this every one minute as you continue to heat the water. Stop it when it is too hot for you.

4. Write down your answer.

  • Warm
  • Very warm
  • Hot
  • Very hot

Note – The teacher is master and leader of this experiment. 

 

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.

6. Summarizes the lesson on the board.

Pupil’s Activities – Copy as the teacher writes.

 

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 (BASIC 5) – Basic Technology

 

LESSON EVALUATION
