What we have learnt
Q1. Why do children always slide down the slide and not slide up? If this slide were there in Sunita’s spacecraft, would children slide like this? Why?

Q2. Why do we see stars mostly at night?
Answer: We see stars only at night because there is no sunlight at night.
Q3. Looking at earth from the space, Sunita said, “Different countries cannot be seen as separate from here. These lines are on paper. They are made by us.” What do you understand by this?
