This pervasive presence of Science underscores its relevance and importance in understanding and improving our world.

Question 11.
What steps should one follow to find answers to scientific questions?
Answer:
Steps to Find Scientific Answers: To find scientific answers, one should follow these steps: observe an interesting phenomenon, ask questions about it, formulate a hypothesis (a possible answer), test the hypothesis through experiments or further observations, and analyze the results to see if they support the hypothesis. This systematic approach helps in drawing accurate conclusions and building a body of scientific knowledge.

Question 12.
Describe the role of curiosity and exploration in the development of scientific knowledge.
Answer:
Curiosity is the spark that ignites the scientific process. It begins when someone wonders about something in the world-like why the sky is blue or how plants grow. This natural curiosity leads to questions, which are the foundation of scientific inquiry.

Exploration is the next step, where scientists actively investigate these questions. They observe, experiment, and analyse data to find answers. For example, a scientist curious about how diseases spread might explore this by studying patterns of infection or experimenting with different treatments.

Through this cycle of curiosity and exploration, scientific knowledge expands. Each discovery often leads to more questions, fueling further exploration.
