6. Motivation
Mother wants to find out if her son has a fever.
What is the best thing mother can use to find the
body temperature of her sick son?

7. Group Activity
Divide the class into four groups. Distribute activity
sheets in each group.
Group 1 with digital thermometer,
Group 2 with set of pictures showing temperature readings
Group 3 using pictorials
Group 4 with alcohol thermometer.

8. Group 1 - Using digital thermometer
Group 2 - Using pictures of temperature readings
Group 3 - Using pictorials
Group 4 – Using alcohol thermometer
Let them discuss how they read and measure the
temperature

9. Processing the Activities
Ask: How did you find the activity?
How were you able to read and measure the
temperature?
Discuss.
Emphasize that ◦C is read as “degree Celsius” it is used
to express temperature. Discuss the difference between
an alcohol and a digital
thermometer.

10. Explore and Discover
A Thermometer is an instrument for measuring
temperature, a unit for measuring temperature if the
degree Celsius (◦C).

11. A thermometer consists of a glass attached to a glass
tube with a number a scale. The liquid in the bulb rises
or drops with change the temperature.
Each space in the number scale represents 1◦C. The
numbers below 0 are written with a minus (-) sign.
To read a thermometer, find the level of the liquid
or the mercury.

12. Normal Body Temperature is 37.5 ℃
Boiling Point of Water is 100 ℃
Freezing Point of Water is 0 ℃

13. Get Moving: What is the temperature for each?
Boiling point of water - ________________
Freezing point of water - ______________
Normal body temperature- _____________
3.5 ◦C higher than the normal body temperature - ____
Between 30◦C to 40◦C - ________
100℃
0℃
37.5℃
41℃
35℃

14. Read the temperature shown in each thermometer

15. Circle what you think is the temperature of the
following:
1.Hot water a. -10◦C b. 30◦C c. 70◦C
2.A person with fever
3.Ice cold tea
4.Bread in oven
5.Ice candy
a. 30◦C b. 35◦C c. 40◦C
a. 10◦C b. 20◦C c. 40◦C
a. 50◦C b. 150◦C c. 290◦C
a. 100◦C b. 35◦C c. 0◦C

16. Summarizing the Lesson
What is a temperature?
How can we measure temperature?
What are the parts of a thermometer?
What is the metric unit for measuring temperature?

17. Summarizing the Lesson
•Temperature is the measure of hotness or
coldness of an object.
•We can measure temperature by using
thermometer.
•The parts of a thermometer are: mercury, glass
tube, glass bulb, and scale.
•The commonly used unit to measure
temperature is degree Celsius ( ◦C ).

18. Assessment
Ask the pupils to find the temperature of the following.
1.Choose the correct estimate of the temperature
of each.
a.Hot coffee 30◦C 85◦C
b.Strawberry shake 5◦C 50◦C
c.Distilled water 20◦C 75◦C
d.High fever 40◦C -15◦C
e.Air conditioned room 10◦C 90◦C

19. Assignment
Ask the pupils to find the temperature of the
following.
1.A kettle of water was made to boil for 5 minutes
more than after it reached its boiling point. What
is the temperature of the water?
2.What is the room temperature if the red liquid
(mercury) rose to 30◦ above the freezing point?
