Long Answer Type Questions (Answer in 60 words each)

​

Question 1. Explain how science can be viewed as a thrilling adventure rather than just a textbook subject.

Answer1 : Science is a thrilling adventure because it turns the entire universe into a playground for discovery. Instead of just memorizing facts from a textbook, science invites us to explore the unknown. From investigating microscopic grains of sand to gazing at vast galaxies, it allows us to act like detectives uncovering the hidden rules of nature.

​

Question 2. Describe the systematic path or method that scientists follow to uncover the truths of nature.

Answer: Scientists follow a structured path called the scientific method to avoid guessing. It begins with making careful observations of patterns in nature. Next, they design experiments to test these observations under different conditions. They then perform an analysis of the data collected, and finally, they draw logical conclusions to establish scientific facts.

​

Question 3 . How does the chapter illustrate that science is deeply integrated into our everyday lives? Provide examples.

Answer: The chapter shows that science is not isolated in distant laboratories; it happens around us daily. In nature, it explains how clouds form or how ants organize themselves. At home, it governs how food cooks or how gadgets function. Even inside us, it controls how we breathe and digest food, proving science is woven into everything we do.
