Question 1

1. Science often begins with a person noticing something unusual or interesting. This first step of looking closely at things is called:

A) CalculationB) InventionC) ObservationD) Conclusion

Answer

✓ Correct Answer: Option C

Explanation: Solution: Science starts with curiosity and Observation. By observing the world around us using our senses, we identify patterns or problems that lead to scientific inquiry.

Question 2

2. A scientist wants to measure exactly 15 mL of water for an experiment. Which tool is most suitable for this task?

A) A large bucketB) A measuring cylinder A weighing scale

Question 3

3. Which of the following best describes the core goal of science?

A) To understand how the natural world worksB) To memorize every fact in a textbookC) To create magic tricksD) To only study space and stars

Answer

✓ Correct Answer: Option A

Explanation: Solution: Science is a systematic way of gaining knowledge to understand how the natural world works through evidence and logic.

Question 4

4. If we find that a plant grows h = 5 cm in the first week and h = 10 cm in the second week, recording these numbers is an example of:

A) GuessingB) ImaginationC) OpinionD) Data Collection

Answer

✓ Correct Answer: Option D

Explanation: Solution: Recording specific measurements (h=5, h=10) is called Data Collection, which scientists use to find trends and draw conclusions.

Question 5

5. Which instrument would you use if you wanted to observe the tiny cells in a leaf that are not visible to the naked eye?

A) TelescopeB) MicroscopeC) PeriscopeD) Stethoscope

Answer

✓ Correct Answer: Option B

Explanation: Solution: A microscope magnifies very small objects, making them appear much larger so we can see details like cells.

Question 6

6. Sir Isaac Newton's curiosity about why an apple falls straight to the ground led to the discovery of:

A) ElectricityB) MagnetismC) GravityD) Photosynthesis

Answer

✓ Correct Answer: Option C

Explanation: Solution: Newton observed the apple falling and formulated the law of universal Gravity, explaining why objects are attracted to the Earth.

Question 7

7. When a scientist says, "I think the sugar will dissolve faster in hot water than in cold water," they are making a:

A) Prediction (Hypothesis)B) Final LawC) Historical FactD) Laboratory Tool

Answer

✓ Correct Answer: Option A

Explanation: Solution: A prediction or hypothesis is an educated guess about what will happen in an experiment before it is tested.

Question 8

8. Which of these is a safe practice to follow while performing a science experiment?

A) Tasting chemicals to see if they are sweetB) Wearing safety goggles to protect the eyesC) Running around the laboratoryD) Mixing random liquids just for fun

Answer

✓ Correct Answer: Option B

Explanation: Solution: Safety is paramount. Wearing safety goggles protects your eyes from accidental splashes or fumes during experiments.

Question 9

9. If the mass of an object is m = 200 g and its volume is $V = 100 cm^3$, the density is $\rho = \frac{m}{V}$. What is the density?

A) $0.5 g/cm^3$B) $100 g/cm^3$C) $2 g/cm^3$D) $20,000 g/cm^3$

Answer

✓ Correct Answer: Option C

Explanation: Solution: Given m = 200 and V = 100. Density $\rho = \frac{200}{100} = 2 g/cm^3$.

Question 10

10. Science is not just found in labs; it is everywhere. Which of these daily activities involves science?

A) Boiling an eggB) Using a mobile phoneC) Predicting the weatherD) All of the above

Answer

✓ Correct Answer: Option D

Explanation: Solution: All of the above involve science. Boiling an egg involves heat transfer, mobile phones use electronics, and weather prediction uses meteorology.

Accepted Answer

✓ Correct Answer: Option B

Explanation: Solution: A measuring cylinder is designed to measure the volume of liquids accurately in units like milliliters (mL).
