  4. Types of Thermometers

Duration: 40 minutes

Behavioral Objectives

By the end of the lesson, pupils should be able to:

  1. Define temperature.
  2. Explain heat.
  3. Differentiate between heat and temperature.
  4. Mention and describe the types of thermometers.

Keywords

  • Temperature
  • Heat
  • Thermometer
  • Joule
  • Degree Celsius
  • Degree Fahrenheit

Set Induction

The teacher will ask pupils:

  • “Have you ever touched something hot, like a cup of tea, or felt cold air from a fan? How did it feel?”
  • This will engage pupils and lead into the lesson on heat, temperature, and how they are measured.

Entry Behavior

The pupils have basic knowledge of energy forms and conversion, which helps them understand heat as a form of energy.

Learning Resources and Materials

  1. Chart showing types of thermometers.
  2. Digital and mercury thermometers (if available).
  3. Pictures of thermometers.
  4. Textbooks.

Types of thermometer

Building Background/Connection to Prior Knowledge

The teacher will remind pupils about energy forms, particularly how energy conversion can result in heat (e.g., rubbing hands together).

Embedded Core Skills

  • Critical Thinking
  • Observation
  • Communication
  • Problem-Solving

Content

1. Definition of Temperature

  • Temperature is the degree of how hot or cold a body or place is.
  • Example: On a sunny day, the temperature of the ground feels hot, while in an air-conditioned room, the temperature feels cold.

2. Explanation of Heat

  • Heat is the movement of energy between two substances with different temperatures (hotter to colder).
  • Example: When you place a cold spoon in hot tea, the heat moves from the tea to the spoon.

3. Difference Between Heat and Temperature

Heat Temperature
Measured by a calorimeter. Measured by a thermometer.
Basic unit is Joule. Basic unit is Kelvin, Celsius, or Fahrenheit.
It is the transfer of energy. It is the measure of hotness or coldness.

4. What is a Thermometer?

  • A thermometer is a device used to measure the temperature of a body or place.
  • Example: Doctors use thermometers to check if a patient has a fever.

5. Types of Thermometers

  1. Digital Thermometers:
    • Use digits to show temperature.
    • Fast and accurate.
  2. Electronic Ear Thermometers:
    • Measure temperature from the ear.
    • Commonly used for babies and children.
  3. Forehead Thermometers:
    • Gun-shaped devices pointed at the forehead to measure temperature.
    • Non-contact and fast.
  4. Glass and Mercury Thermometers:
    • Commonly used in hospitals.
    • Can be placed under the tongue or armpit.
