An Experiment to Show Daily Changes in Temperature By Plotting A Graph:

Requirements:

A centimeter graph sheet, temperature data from the local newspaper for 55 days, red and blue pencils

Procedure:

Note down the date and the maximum and minimum temperatures from the newspaper for 55 days.
On a graph sheet, plot the date on the x-axis and the corresponding maximum temperatures on the y-axis.
Join these points with a red pencil to get the maximum temperature graph.
Repeat Step 2 for the minimum temperatures. Now join the points with the blue pencil to get the minimum temperature graph.

Observation:

A curved graph is obtained. A red line shows the maximum temperature and blue line shows the minimum temperature.

Conclusion:

An Experiment to Show Changes in Length of the Day By Plotting A Graph:

Requirements:

A centimeter graph sheet, data from the local newspaper for at least ten days, a sharp pencil, and an eraser

Procedure:

Note the time of sunrise and sunset from the daily newspaper for ten consecutive days.
Find the difference in the times to get the duration of each day, i.e., day length.
On a graph sheet, plot the date on the x-axis and the day length on the y-axis.

Conclusion:

An Experiment to Show Daily Changes In Humidity By Plotting A Graph:

Requirements:

A centimeter graph sheet, data from the local newspaper for at least five months, a sharp pencil, and an eraser

Procedure:

Note the humidity content given in the weather report of the daily newspaper for five months.
Plot the date on the x-axis and the humidity on the y-axis.
Note down the trend that is observed in the graph.

Observation:

Conclusion:

Humidity is not the same every month. Sometimes it is low and sometimes high.
As climate differs from place to place, different animals adapt to these climates.
