CONTENT OF THE LESSON
LESSON ONE – INTRODUCTION
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.
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.
Thermometer is an device used for measuring temperature of a body. For example, how hot or cold is water, food, iron, human body, etc.
UNITS AND SYMBOLS OF TEMPERATURE SCALE
DEGREE CELSIUS (°C)
Hint — °C to °F, Divide by 5, then multiply by 9, then add 32
Convert 25° Celsius to Fahrenheit.
First, 25°/5 = 5
Then, 5 × 9 = 45
Then, 45 + 32 = 77° F
Convert 30º Celsius to Fahrenheit.
First, 30ª/5 = 6
Then, 6 x 9 = 54
54 + 32 = 86º F
1. 20º Celsius
2. 15º Celsius
LESSON TWO – UNITS AND SYMBOLS OF TEMPERATURE SCALE
DEGREE FARENHEIGHT (°F)
Hint —°F to °C: Subtract 32, then multiply by 5, then divide by 9.
Convert 77º Fahrenheit to degree Celsius.
First, 77º — 32 = 45
Then, 45 x 5 = 225
225/9 = 25º Celsius
Convert 86º Fahrenheit to degree Celsius.
First, 86º —32 = 54
Then, 54 x 5 = 270
270/9 = 30º Celsius
1. 68º Fahrenheit
2. 59º Fahrenheit
LESSON THREE – SOME USES OF THERMOMETER
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. Provides the pupils with different types of thermometers.
3. Uses charts to guide the pupils to identify and name the units and symbols for temperature.
Pupil’s Activities – Identify the units and symbols of temperature.
4. Guides pupils to state the relationship Celsius and Fahrenheit.
Pupil’s Activities – Concert one unit to another.
5. Discusses the uses of thermometer.
Pupil’s Activities – Participate in the class discussion.
- To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
1. write the units and symbols of temperature
2. use thermometers to measure temperature accurately.
