Q1.
How can we measure and monitor the weather around us?
Answer:
We can measure and monitor the weather using special instruments and tools. Here are some examples:

  1. Thermometer: Measures temperature (how hot or cold it is).
  2. Rain Gauge: Measures the amount of rainfall ‘ (in millimeters or centimeters).
  3. Barometer: Measures atmospheric pressure, which helps predict weather changes.
  4. Anemometer: Measures wind speed (how fast the wind is blowing).
  5. Wind Vane: Shows the direction of the wind (north, south, east, or west).
  6. Hygrometer: Measures humidity (the amount of water vapor in the air).

Q2.
How do weather predictions help us prepare for events like heavy rain, storms, drought and heat waves?
Answer:
Weather predictions give us advance information about upcoming weather events, which helps us prepare and stay safe. For example:

  1. Heavy Rain: Predictions warn us to carry umbrellas, avoid flooded areas, and protect our homes from water damage.
  2. Storms: We can secure loose objects, stay indoors, and prepare emergency kits with food, water, and medicines.
  3. Drought: Farmers can plan irrigation and water storage to save crops, and people can conserve water.
  4. Heat Waves: We can stay hydrated, avoid going out during peak heat, and use fans or coolers to stay comfortable.

Q2.
What do you think could be some other reasons to measure the weather more precisely?
Answer:
Yes, measuring the weather more precisely has many important reasons. Here are some of them:

  1. Planning Daily Activities: Knowing the weather helps people plan their day, like deciding whether to carry an umbrella, wear warm clothes, or stay indoors during extreme heat or rain.
  2. Agriculture: Farmers rely on accurate weather forecasts to decide when to plant crops, irrigate fields, or harvest. This helps them grow better crops and avoid losses.
  3. Disaster Preparedness: Precise weather measurements help predict natural disasters like cyclones, floods, or droughts. This allows governments and people to prepare and take safety measures in advance.
  4. Aviation and Transportation: Pilots and drivers need accurate weather information to ensure safe travel. For example, knowing about storms or fog helps avoid accidents.
  5. Environmental Monitoring: Accurate weather measurements help scientists study climate change, track pollution levels, and protect the environment.

Q4.
(a) Here’s a chart of the temperatures of a city in Madhya Pradesh. What is the maximum temperature recorded in the week shown here? What is the minimum temperature? Calculate the range.

DateMaximum Temperature (in °C)Minimum Temperature (in °C)
28.02.20252916
01.03.20253015
02.03.20253117
03.03.20253218
04.03.20253017
05.03.20252814
06.03.20252915

Answer:
Maximum temperature recorded in the week: From the chart, the highest maximum temperature is 32°C (on 3.3.2025).
Minimum temperature recorded in the week: The lowest minimum temperature is 14°C (on 5.3.2025).

Temperature range: Range = Maximum temperature – Minimum temperature = 32°C – 14°C = 18°C

(b) Remember the conservation between Krishnan and Amir? If Krishnan said it was 20 degree Celsius in Chennai and that he was feeling a little cold, both he and Amir would have a measure they could understand. What do you think Amir’s reaction to Krishnan’s statement might be? (Page 33)
Answer:
If Krishnan said it was 20°C in Chennai and that he was feeling a little cold, Amir might be surprised and say something like:
“Really? 20 degrees is quite comfortable here! In Madhya Pradesh, we only start feeling cold when it’s much lower than that.”

This highlights how climate and personal experience influence how we perceive temperature. Chennai has a hot and humid climate most of the year, so 20°C can feel cool to someone used to higher temperatures. Meanwhile, someone from central or northern India, like Amir, might find it quite normal or even warm.
