NCERT Book Class 7 Science (Curiosity) Chapter 1 The Ever-Evolving World of Science

The Ever-Evolving
1 World of Science

We hope you enjoyed your adventures with Curiosity in
Grade 6, and are now ready to continue our journey into the
wonderful world of science. This again, is not just a textbook with
facts — it is an invitation to question, to perform experiments,
and to explore, as we try to understand the beautiful world we
live in. The world of science covers everything — small and large,
near and far. We may be looking at tiny cells inside a leaf, or
the movement of the sun and the stars. We may be testing out
the materials around us at home, or discussing how water flows
underground. As you go through the chapters in this book, you
will start new adventures that challenge your thinking, expand
your knowledge, and help you become an explorer, making small
discoveries for yourself.
Before we dive into our exciting journey, take a moment to
observe something special about this book. Look at the page
numbers — they follow the playful flight of a butterfly and the
soaring of a paper plane! Just as a butterfly flutters freely and a
paper plane flies into the sky, learning takes flight when curiosity
leads the way. Did you know that something as simple as a paper
plane inspired real scientific explorations of flight? From early
inventors studying bird wings to modern engineers designing
aircraft, the dream of flying started with simple observations and
experiments. So, as you turn each page, let your imagination take
flight — exploring new ideas, discovering wonders, and reaching
for the skies!
