Answer: Asking “Why?” helps us discover reasons behind things, learn new facts, understand the world better, and think deeply.

If your torch suddenly stops working, how would you use the scientific method to find the problem?
Answer: Observe the torch → Ask what went wrong → Guess possibilities (battery weak or bulb fused) → Test by changing the battery → Conclude the correct cause.
Why do you think discoveries can come from unexpected places like kitchens or playgrounds?
