Temperature Measurement for Class 2 Maths

In our daily life, hot and cold are measured. This measure of hot and cold is known as Temperature. In this learning concept, students will learn about temperature measurement. They will learn about how Temperature is measured in degrees.

In this learning concept, students will learn:

  • About the temperature measuring device thermometer.
  • Parts of thermometers and different types of thermometers.
  • Also, the relation between Celsius and Fahrenheit.

Each concept is explained to class 2 maths students using illustrations, examples, misconceptions, and mind maps. Students can assess their learning by solving the two printable worksheets at the pages’ end.
Download the measurement of temperature worksheet for class 2 and check the solutions for the concept of measurement of Temperature provided in PDF format.

Temperature tells us how hot or cold something is.

Examples:

Hot and Cold
  • Tea is hot, it has a higher temperature.
  • Ice cream is cold; it has a lower temperature.
hot and cold
  • Soup is hot, it has a higher temperature.
  • Juice is cold, it has a lower temperature.
  • By slightly touching the above objects, we can easily say whether it is hot or cold.
  • Hot objects have higher temperatures.
  • Cold objects have lower temperatures.

Hot and Cold Weather

  • When we go out on a summer afternoon, we feel very hot.
  • It means the temperature is high on a summer day.
cold weather images
  • When we go out on a snowy evening, we feel very cold.
  • It means the temperature is low on a snowy day.

Temperature Measuring Devices:

  • By touching an object, we can identify whether it is hot or cold, but we can’t measure the temperature of the object. Because temperature is the degree of hotness or coldness.
  • We can measure the temperature by using an instrument called thermometer.

Thermometer:

  • Thermometer is a device used to measure Temperature.

Parts of Thermometer:

  • Glass tube: Glass tube is a long cylindrical tube that is connected to the bulb.
  • Bulb with a liquid: The bulb is the lowest part of the thermometer, and has a spherical shape. Here, Mercury stays in liquid form. When the temperature is getting high, mercury in the bulb moves up in the glass tube.
  • Temperature scales: There are marked scales with numbers on both sides with respect to units of the temperature.
  • There are mainly two types of units of Temperature on a thermometer–
    1. ℃ – C stands for Celsius
    2. ℉ – F stands for Fahrenheit

Did you know?

Celsius and Fahrenheit are the names of the people who invented each of these units.

Did you know
  • United States and some other countries use the Fahrenheit unit.
  • Rest of the countries in the world use Celsius unit.

Relation Between Celsius and Fahrenheit

relation between Celsius and fahrenheit

32 ℉ = 0 ℃

  • 32 ℉ is equal to 0 ℃.
  • In India we use a Celsius unit to measure temperature.

How to Read Thermometer:

Example 1:

  • We will measure the temperature of the boiling water.

  • After putting the thermometer in the hot water, the thermometer’s mercury level reached at the number 100.
  • Water boils at 100℃ temperature. It’s too hot.

Example 2:

  • We will measure the temperature of the ice.
    ice images
  • After putting the thermometer on the cold ice, the thermometer’s mercury level reached at the number 0.
  • Water freezes into ice at 0℃ temperature. It’s too cold.

Example 3:

  • We will measure the temperature of the normal glass of water.
    glass of water images
  • After putting the thermometer in the normal glass of water, the thermometer’s mercury level reached at the number 20.
  • Temperature of the glass of water is 20℃. It’s a normal temperature.
  • When temperature is increasing, mercury level goes up.
  • When temperature is decreasing, mercury level goes down.
  • By observing the mark of the mercury level, we can measure
    the temperature of the object.

New words:

Freeze: To become hard (and often change into ice) because of extreme
cold.

We made a snowman in our balcony. It is frozen and stands like statue.
