Collaboration in science fosters creativity, peer review, and validation of research findings.
Long Answer Type Questions
Question 1.
Ho you think curiosity plays a crucial role in the study of science? If yes, give reason to substantiate your answer.
Answer:
Role of Curiosity: Curiosity is the driving force behind scientific inquiry. It motivates us to ask questions and seek answers, leading to new discoveries and a deeper understanding of the world. Without curiosity, the journey of scientific exploration would not be as engaging or fruitful. It is curiosity that sparks our interest in studying various phenomena and pushes us to find explanations for the mysteries we observe.
Question 2.
Why can Science be described as a big adventure?
Answer:
Science as a Big Adventure: Science is described as a big adventure because it involves exploring the unknown, asking questions, and making discoveries. The study of Science is an adventurous journey where we continuously Uncover new pieces of knowledge, much like solving a giant jigsaw puzzle. Each discovery leads to more questions and further exploration, making the process exciting and never- ending.
Question 3.
How does Science help us understand natural phenomena like the blooming of a flower or the shining of stars?
Answer:
Understanding Phenomena: Science helps us understand natural phenomena by providing explanations based on observation, experimentation, and analysis. Through scientific inquiry, we learn about the processes and mechanisms behind these phenomena, such as nuclear fusion in stars or the role of environmental cues in flowering.
Question 4.
Why is the Earth considered a special planet?
Answer:
Earth as a Special Planet: The Earth is considered special because it is the only known planet that supports life. The variety of plants and animals that thrive in different regions of the Earth. The unique ability of Earth to harbor life makes it a focal point of scientific study.
Question 5.
What are some of the daily life situations mentioned in the passage where Science can be applied?
Answer:
Daily Life Situations Applying Science: The passage provides examples of daily life situations where Science is applied, such as figuring out why a pen stops writing, determining why dal spills out of a cooker, identifying the source of a flat bicycle tire, and troubleshooting a non-working light bulb. These examples illustrate how the scientific method is used in everyday problem-solving, demonstrating that Science is not confined to laboratories but is an integral part of our daily lives.
Question 6.
Explain the scientific method using the example of a pen that stops writing.
Answer:
Scientific Method and Pen Example: When a pen stops writing, the scientific method involves observing the problem, asking why it happened, guessing possible reasons (hypotheses), and testing these guesses. For instance, one might guess that the ink is finished and check the refill. If the ink Ts not finished, another guess might be that the ink dried up. Testing this hypothesis could involve trying to unclog the pen. This step-by-step process of hypothesizing and testing is the essence of the scientific method.
