Reference Materials

The following resources were used in planning this lesson:

9 – Years Basic Education Curriculum
Abuja Educational Resource Center Scheme of Work
NAPPS National Unified Scheme of Work
Online Information from: Labomat – How to measure the temperature?
Relevant Textbooks: “Basic Science and Technology for Primary Schools”

Instructional materials

To deliver this lesson, the teacher will employ the help of the following materials:

Thermometers (both Celsius and Fahrenheit)
Ice water and hot water
Charts of temperature scales
Whiteboard and markers
Measuring containers

Rationale for the lesson

Understanding how to measure temperature is vital because it helps pupils make sense of temperature changes in their habitat, such as whether something is hot or cold.This skill is used daily when cooking, working with appliances, and even understanding the weather. It also introduces the concepts of Celsius and Fahrenheit, both of which are used worldwide for scientific purposes.

Prerequisite/Previous Knowledge

Pupils should already be familiar with the concepts of temperature, the use of thermometers, and the basic symbols for temperature measurement (°C and °F), having learned about the units and symbols in the previous lesson.

Lesson Content

Measuring Temperature of Objects in °C and °F

Temperature is a measure of how hot or cold an object is. We can measure it using a thermometer. There are two main scales for measuring temperature: Celsius (°C) and Fahrenheit (°F).

Measuring Temperature of Objects in Celsius (°C)

Measuring temperature in Celsius involves using a thermometer calibrated to the Celsius scale to determine the degree of hotness or coldness of an object.

The following are the steps to measure temperature in Celsius (°C):

To measure temperature in °C, place the thermometer in or near the object you wont to measure.
Wait for a few seconds until the thermometer gives a steady reading.
For example, the temperature of ice water is 0°C, and the temperature of boiling water is 100°C.

Measuring Temperature of Objects in Fahrenheit (°F)

Measuring temperature in Fahrenheit involves using a thermometer calibrated to the Fahrenheit scale to determine the degree of hotness or coldness of an object.The following are the steps to measure temperature in Fahrenheit (°F):

To measure temperature in °F,the same steps apply,but the scale is different.
Such as, ice water will be at 32°F, and boiling water will be at 212°F.

Lesson Keywords

Temperature – A measure of how hot or cold something is.
Celsius (°C) – A temperature scale where 0°C is the freezing point of water and 100°C is the boiling point.
Fahrenheit (°F) – A temperature scale where 32°F is the freezing point of water and 212°F is the boiling point.

Measurement – The process of finding the size, quantity, or degree of something.

Lesson Evaluation

to evaluate the learning, the teacher asks pupils to:

What is the unit of measurement for Celsius and Fahrenheit?
How do you measure the temperature of an object in °C?
If you placed a thermometer in boiling water, what temperature would you expect to see in Celsius and Fahrenheit?
What is the difference between the Celsius and Fahrenheit scales?
How can you ensure the thermometer reading is accurate?
