Understanding weather reports in Weather and Climate – Class 7 Science Experiment

Chapter Name: Weather and Climate

Activity Name: Understanding weather reports in Weather and Climate

Activity Description:

The experiment involves analyzing two weather reports to understand their content, purpose, and the differences between them. Report 1 is a weather forecast, and Report 2 is a weather report.

Required Items:

1. Weather reports (Report 1 and Report 2)

Step by Step Procedure:

1. Obtain Report 1 and Report 2.
2. Read and analyze each report carefully.

Experiment Observations:

1. Report 1 (Weather Forecast):
   • Mentions the possibility of isolated rain or thunder showers in specific districts (Chittoor, Nellore, Prakasham, and some parts of Kadapa).
   • Predicts mainly dry weather in southern Telangana districts and northern coastal districts of Andhra Pradesh.
   • Indicates cloudy sky in Kurnool and Ananthapur districts for the next two days.
2. Report 2 (Weather Report):
   • Provides past data: Maximum temperature of 42°C recorded at Ramagundam in Karimnagar district, and minimum temperature of 29°C recorded at Aarogyavaram in Chittore district.
   • Mentions 2mm of rainfall in Hyderabad due to cumulonimbus clouds.
   • Notes scattered rainfall in some parts of interior Rayalaseema and dry conditions in the remaining part of the state.

Precautions:

1. No specific precautions are mentioned as this activity involves reading and analyzing weather reports.

Lesson Learnt from Experiment:

From the experiment, learners understand the differences between a weather forecast and a weather report:

• Weather Forecast (Report 1) predicts future weather conditions, giving information about the likelihood of rain, temperature trends, and general weather patterns in specific regions for the next few days.
• Weather Report (Report 2) provides past weather data, including the maximum and minimum temperatures, recorded rainfall, and current weather conditions.

Both reports discuss various aspects of the weather, such as temperature, rainfall, and sky conditions, but they serve different purposes: one predicts future weather, while the other reports past weather events. Understanding the difference between these two types of reports is essential for comprehending weather information accurately.
