The document describes a conversation between Shiva and his grandfather to help Shiva understand what makes objects heavier or lighter. The grandfather has Shiva hold different objects, like a book and sharpener, to demonstrate that the book feels heavier after a while. They also discuss how a lock is heavier than a crayon. Finally, they watch a video to reinforce the lesson that heavier objects are harder to lift than lighter ones.

1. Who is Heavier?

2. Once Shiva’s grandpa came from
Shimla to his house.
He was carrying his
suitcase.

3. Shiva ran and picked up the suitcase
but he was not able to lift it.

4. Grandpa , why
am I not able to
lift the suitcase?
You are not able
to lift the
suitcase because
it contains heavy
things inside it.
What do you
mean by heavy
things?
Ok.I’ll explain. Bring
things like eraser,
pencil,lock, glass of
water, etc.

5. Shiva goes and gets the things

6. Now hold the
sharpener in one
hand and the
book on the other
hand
sharpener
Well! Tell me
which object can
you hold for a
longer time
Ok,
grand
pa

7. Why?
Because
my left
hand was
paining
That’s
because the
book is
heavier than
the
sharpener.
That means
heavier things are
difficult to carry,
and lighter things
easy to carry
Yes,now you
understood
what is meant
by heavier
objects.

me which one
will be heavier
than the other
A lock A crayon
