Q1.
Draw any pattern you have observed, in the box below:The empty box printed in the book.
Answer
You must look at the real night sky first. Then draw what you saw.
Go out about an hour after sunset, with an elder. Choose an open place away from bright lights.
Wait for five minutes so that your eyes get used to the dark. Many more stars will appear.
Look for a group of bright stars that seem to make a shape.
Mark each bright star as a dot in the box. Keep the dots in the same places as in the sky.
Join the dots with light pencil lines. Give your pattern a name.
Sample answer: a well-known pattern of seven bright stars. In India it is called Saptarshi, the Seven Sages.
A sample star pattern: seven bright stars joined by lines.
Why we see patterns: The stars do not really touch one another. Our eyes simply join bright dots that lie near each other, the way we see shapes in clouds. That is why the same seven stars have been given different names by different people.
Tip: Your pattern does not have to be Saptarshi, and it does not have to match your friend’s. Any group of stars you noticed yourself is a correct answer. The point of the activity is to make you look up.
Q2.
Share the drawing with your friends and discuss the common patterns of stars.
Answer
Do this in class the next morning.
Pin all the drawings on one wall or lay them on a table.
Look for drawings that show the same group of stars. Put them together.
Ask each friend what they named their pattern.
Make one class list: pattern, who saw it, and the names given to it.
What you will find: a few patterns come up again and again, because everybody was looking at the same sky. The group of seven bright stars is usually drawn by many children. But the names differ — one child calls it a pot, another a kite, another Saptarshi.
Sample answer: “Seven of us drew the same seven bright stars. Asha called it ‘the big spoon’. Iqbal called it ‘the plough’. My grandmother calls it Saptarshi.”
Why this is worth doing: Sharing shows that the sky is the same for everyone in your town, but the shape you see in it is your own idea. Both are true at once.
