Measuring Weather: Temperature

Active learning helps children connect abstract temperature readings to real-life experiences, making the concept of weather measurement concrete and memorable. By handling thermometers and observing changes in their surroundings, students develop both observational skills and numerical literacy in a way that worksheets alone cannot achieve.

• CBSE Learning Outcomes
• NCERT, Learning Outcomes at the Elementary Stage, EVS Class 2: Identifies different types of weather (sunny, rainy, windy, cloudy).
• CBSE Syllabus, Class 2 EVS, Theme: Weather and Seasons: Observes and describes daily changes in weather.
• NCERT Syllabus, Class 2 EVS, Theme: Air, Water and Weather: Relates the type of weather to appropriate clothing and activities.

Thermometer Reading Game

Children take turns reading a classroom thermometer and outdoor one. They record numbers on a chart and discuss differences. This builds observation skills.

Explain how a thermometer helps us know how hot or cold it is.

Facilitation Tip

During the Thermometer Reading Game, circulate and gently correct students who read the scale upside down by asking, 'Which number is closer to the top of the thermometer?'

What to look for

Hold up a thermometer showing a specific reading (e.g., 25°C). Ask students: 'Is it hot or cold today? What clothes would you wear if the thermometer showed this temperature?'

Activity 02

• Experiential Learning
• 15 min · Small Groups

Hot and Cold Hunt

Place hot water, cold water, and room temperature samples. Children feel and predict thermometer readings before measuring. Relate to daily weather.

Compare the temperature inside our classroom to outside.

Facilitation Tip

While doing the Hot and Cold Hunt, pair students and ask them to explain their choices to each other to reinforce vocabulary like 'hot', 'cold', and 'degrees'.

What to look for

Ask students: 'Imagine you are going to play outside. What would you do differently if the temperature was 40°C compared to 15°C? Why?' Encourage them to use the terms 'hot', 'cold', and 'degrees Celsius'.

Weather Prediction Chart

Children draw activities for hot, cold, and mild days based on temperature predictions. Share as a class.

Predict what activities we would do on a very hot day versus a very cold day.

Facilitation Tip

For the Weather Prediction Chart, model how to record predictions by filling in the first row together before asking students to do the rest.

What to look for

Give each student a small card. Ask them to draw a thermometer showing a 'cold' day and write one activity they would do inside. Then, ask them to draw a thermometer showing a 'hot' day and write one activity they might do outside (if safe).

Compare Indoor Outdoor

Measure and compare temperatures inside and outside at different times. Discuss reasons for changes.

Explain how a thermometer helps us know how hot or cold it is.

Facilitation Tip

During Compare Indoor Outdoor, place one thermometer near the window and one in the shade to show how location affects readings.

What to look for

Hold up a thermometer showing a specific reading (e.g., 25°C). Ask students: 'Is it hot or cold today? What clothes would you wear if the thermometer showed this temperature?'

A few notes on teaching this unit

Start with hands-on exploration before introducing theory to build schema. Avoid long explanations about mercury or alcohol; focus instead on the visual rise and fall of the liquid. Research shows that young children learn temperature best through direct observation and comparison rather than abstract explanations. Use real thermometers whenever possible, as toy versions often lack accurate scales.

By the end of these activities, students will confidently read a thermometer scale in degrees Celsius, identify temperature changes throughout the day, and connect these readings to appropriate clothing and activities. They will also understand that temperature is measured by liquid expansion, not by touch.

Watch Out for These Misconceptions

• During the Thermometer Reading Game, watch for students who believe temperature can be measured by touching the thermometer with their hands.

  During the Thermometer Reading Game, remind students that the liquid inside rises or falls based on the air around it, not because of their touch. Ask them to hold the thermometer by the top and observe the red line without touching the bulb.

• During the Hot and Cold Hunt, watch for students who think 40°C is always hotter than 15°C regardless of the scale used.

  During the Hot and Cold Hunt, hold up a thermometer and point to the scale, saying 'See how the numbers go up? This is in degrees Celsius, which is what we use in India. Higher numbers mean hotter here.'

• During the Weather Prediction Chart, watch for students who assume the temperature stays the same all day.

  During the Weather Prediction Chart, ask students to recall the hottest part of their day and mark it on the chart. Say, 'Why do you think the afternoon is warmer? What happens to the sun at that time?'
