Q1.
Observe the Moon in the sky and draw the shapes of the Moon you have observed on different nights.The nine empty boxes printed in the book.
Answer
This is a watching job. Keep a Moon diary for about two weeks.
Pick one time — say eight o’clock at night — and go out at that time every night.
Find the Moon. Write the date in a corner of the box.
Draw a circle first, lightly. Then shade the dark part and leave the bright part white.
Use one box for each night. If clouds hide the Moon, write “cloudy” and use the next box.
Keep going till you have filled all nine boxes.
What your nine boxes will show: the shape changes a little every night, and it changes in order — never by jumping about.
Sample answer:
The order in which the Moon’s shape changes, night after night.
A night when the Moon is a complete circle is Poornima, the full Moon.
A night when the Moon is not visible at all is Amavasya, the new Moon.
In between you will see the ‘C’ shape and the half shape, as if the Moon has been cut down the middle.
Why this is worth doing: Ancient people did exactly this. They used the shape of the Moon to keep count of the days, and that gave rise to the earliest calendars.
Tip: Look on a few nights soon after sunset and on a few nights later. On some days the Moon rises late, so you may have to wait. A cloudy night is not a failed night — write it down and carry on.
