Measuring and recording the temperature in Weather and Climate – Class 7 Science Experiment
Chapter Name: Weather and Climate
Activity Name: Measuring and recording the temperature in Weather and Climate
Activity Description:

In this experiment, Pravin measures the temperature of his village using MMT (a temperature measuring instrument) over a period of five days. He then expresses his observations through a graph to visualize the changes in maximum temperature over time.
Required Items:
- MMT (temperature measuring instrument)
- Recording sheet or notebook
- Pen or pencil
- Graph paper (for plotting the graph)
Step by Step Procedure:
- Set up the MMT (temperature measuring instrument) and ensure it is calibrated correctly for accurate readings.
- On Day 1 (10th December 2011), go to the location where you want to measure the temperature in your village.
- Use the MMT to measure and record the maximum temperature for the day. Write down the date and the temperature (in degrees Celsius) in a recording sheet or notebook.
- Repeat the temperature measurement process for the next four days (Day 2 to Day 5) in the same manner, recording the dates and maximum temperatures each day.
Experiment Observations:
- The recorded data of maximum temperatures for five consecutive days is as follows:
- Day 1 (10 – 12 – 2011): 31°C Day 2 (11 – 12 – 2011): 32°C Day 3 (12 – 12 – 2011): 32°C Day 4 (13 – 12 – 2011): 32°C Day 5 (14 – 12 – 2011): 32°C
Precautions:
- Ensure the MMT is calibrated and accurate before starting the measurements.
- Choose a location that is representative of the overall temperature in the village, away from any artificial heat sources or shade that may affect the readings.
- Take measurements at the same time each day to minimize the impact of daily temperature fluctuations.
- Handle the MMT carefully to avoid any damage that might affect its accuracy.
Lesson Learnt from Experiment:
The experiment demonstrates how to measure and record the maximum temperature using a temperature measuring instrument (MMT) over a period of time.
The recorded data can be visualized through a graph, which helps to observe the variations in maximum temperature over the given days. In this particular case, the observations indicate that the maximum temperature remained constant at 32°C from Day 2 to Day 5, while it was slightly lower at 31°C on Day 1.
This could indicate stable weather conditions during this period. However, further analysis and data from additional days would be necessary to draw more conclusive insights about the weather and climate patterns in Pravin’s village.
