Just then, Aryan’s eyes lit up. “What if we use something round,
like a wheel? When I roll my toy cart, it feels easy to move.”
Aditi nodded, and said, “Let’s ask Swati didi! She is always fixing
the bucket from the well, and she was finding it hard to do it.”

Grandmother tried it and was amazed. “Wah! This is wonderful!
Later, as the siblings sat by the well, Aryan said, “We learned so
much today! Force is everywhere—when we push doors, pull
water, or even lift our school bags. And gravity is always pulling
things down.”
“And simple machines like the pulley help us make work easier,”
Aditi added. She continued, “If we could invent something to
help Grandma today, imagine what else we could make in the
future!”
“Exactly!” Swati said. “With creativity and teamwork, you can
solve any problem.”
Aryan’s eyes sparkled. “Yes! Maybe we can build something to
carry sacks of wheat or even help mother in the kitchen!”
Swati giggled. “That’s the spirit! There are so many simple
machines around us—like levers, wheels, and inclined planes.
Who knows what you’ll create next?”
Aditi and Aryan looked at each other, excited. “Let’s explore
more and see what we can invent next!”
With that, the two siblings ran off, dreaming of their next big
idea.
