50 Very Short Answer Questions & Answers
Q1: What is science? Science is a way of learning about the world using observations and experiments.
Q2: What do scientists do? Scientists observe, ask questions, perform experiments, and explain results using evidence.
Q3: Define observation. Observation is noticing and recording facts or events carefully.
Q4: What is a hypothesis? A hypothesis is a simple, testable guess or explanation for an observation.
Q5: Why do we perform experiments? To test hypotheses and collect evidence to support or reject ideas.
Q6: Give one example of an everyday scientific tool. A torch (flashlight) is an everyday tool that shows use of electricity and light.
Q7: What is evidence? Evidence is the information collected from observations and experiments.
Q8: What does recording observations mean? Writing down what we see, measure or notice during an experiment.
Q9: What is a conclusion? A conclusion is the final idea or answer after analysing the evidence from an experiment.
Q10: Why is curiosity important in science? Curiosity leads to asking questions and exploring new ideas, which drives science.
Q11: What is classification? Grouping objects based on similar properties is called classification.
Q12: Give one example of classification. Sorting clothes as cotton, wool, and synthetic is an example of classification.
Q13: What is a fair test? A fair test changes only one factor at a time while keeping others the same.
Q14: What are variables? Variables are factors in an experiment that can change or be changed.
Q15: What is measurement? Measurement is finding the size, length, weight, or quantity using standard units and tools.
Q16: Name one measuring tool. A ruler (for length) or a measuring cup (for volume).
Q17: Why use standard units? Standard units allow everyone to understand and compare measurements easily.
Q18: What is an experimenter’s record? It is a notebook or table where observations and results are written down.
Q19: What is the role of models in science? Models are simple representations that help explain complex ideas or processes.
Q20: Give one example where science improves life. Medicine helps cure diseases, improving health and life expectancy.
Q21: What is a scientific fact? A scientific fact is an observation that has been repeatedly confirmed.
Q22: Can scientific ideas change? Yes, ideas change when new evidence or better explanations are found.
Q23: What is safety in science experiments? Safety means using care, wearing protection and following instructions to avoid harm.
Q24: Why write steps in an experiment? Steps help others repeat the experiment and check the results.
Q25: What is a simple observation activity at home? Observing how sugar dissolves in water and noting the time taken is a simple activity.
Q26: What does 'investigation' mean? Investigation means carefully finding out information to answer a question.
Q27: What is predict in science? To predict is to give a possible outcome before doing an experiment.
Q28: What is a control in an experiment? A control is a standard used for comparison that is not changed during the experiment.
Q29: Why discuss results with others? Discussion helps check ideas, find mistakes and learn different viewpoints.
Q30: What is evidence-based decision? Making a decision using facts and observations rather than guesses.
Q31: How does science help in daily life? Science helps make food, solve illnesses, create tools, and improve transportation.
Q32: What is a scientist? A scientist is someone who studies nature and finds explanations using evidence.
Q33: Give an example of observation during a plant study. Noting that a plant’s leaves turn towards light is an observation.
Q34: What is a simple hypothesis example? If plants get more light, then they will grow taller — is a simple hypothesis.
Q35: What does 'record' mean in science? To write down numbers, drawings or notes about what you saw in an experiment.
Q36: What is the importance of repeating an experiment? Repetition checks if results are consistent and reliable.
Q37: What is a qualitative observation? An observation describing qualities like colour, texture or smell.
Q38: What is a quantitative observation? An observation using numbers or measurements, like 5 cm or 2 minutes.
Q39: Why draw diagrams? Diagrams help explain ideas clearly and show parts of an experiment or object.
Q40: What is a simple experiment for 'change'? Melting ice and observing water formation shows change due to heat.
Q41: How can we test a guess? By doing an experiment that compares results with and without the tested change.
Q42: What is an observation table? A table to record observations in rows and columns for clarity.
Q43: What is accurate measurement? Using the correct tool and reading it carefully to get a true value.
Q44: Why ask "why" questions? Asking why helps find causes and understand how things happen.
Q45: What is a simple way to show 'sorting'? Group fruits into those with seeds and without seeds.
Q46: What is 'change around us'? It refers to everyday changes like growth, melting, rusting and drying.
Q47: Why use drawings in reports? Drawings show what was done and help others repeat the experiment.
Q48: What does 'compare' mean? To look for similarities and differences between two or more things.
Q49: Give a simple conclusion example. "Salt dissolves in water" is a conclusion based on observation.
Q50: Why are these study materials useful? They follow the NCERT syllabus closely and help students prepare for CBSE exams with clear concepts.
