Collect weather reports of seven successive days in the winter months (preferably December). Collect similar reports for the summer months (preferably June). Now prepare a table for sunrise and sunset times as shown:
Table

June

December

Date	Sunrise	Sunset	Date	Sunrise	Sunset

Try to answer the following questions:
(i) Is there any difference in the time of sunrise during summer and winter?
(ii) When do you find that the sun rises earlier?
(iii) Do you also find any difference in the time of sunset during the month of June and December?
(iv) When are the days longer?
(v) When are the nights longer?
(vi) Why are the days sometimes longer and sometimes shorter?
(vii) Plot the length of the day against the days chosen in June and December.
(Instructions for plotting graphs are given in Chapter 13.)"

A table for sunrise and sunset times is shown below:                                                        

Correct answers:

(i) Yes. There is a difference in the time of sunrise during summer and winter.

(ii) The sun rises earlier during summer.

(iii) Yes. There is a difference in the time of sunset between June and December. In December, the Sunset is earlier compared to the month of June.

(iv) During summer, the days are comparatively longer than in winter.

(v) During winter, the nights are comparatively longer than in summer.

(vi) Due to Earth's revolution around the sun, the angle of Earth around the sun changes. This creates a difference in the length of day and night.
