Grade 6 : Science (Curiosity) - The Wonderful World of Science (Set 1) | Concept of Maths

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) Calculation

B) Invention

C) Observation

D) Conclusion

Answer

Correct Answer: C

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 $15 \text{ mL}$ of water for an experiment. Which tool is most suitable for this task?

A) A large bucket

B) A measuring cylinder

C) A weighing scale

D) A thermometer

Answer

Correct Answer: B

Solution: A measuring cylinder is designed to measure the volume of liquids accurately in units like milliliters ($\text{mL}$).

Question 3

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

A) To understand how the natural world works

B) To memorize every fact in a textbook

C) To create magic tricks

D) To only study space and stars

Answer

Correct Answer: A

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 $h = 5 \text{ cm}$ in the first week and $h = 10 \text{ cm}$ in the second week, recording these numbers is an example of:

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) Telescope

B) Microscope

C) Periscope

D) Stethoscope

Answer

Correct Answer: B

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) Electricity

B) Magnetism

C) Gravity

D) Photosynthesis

Answer

Correct Answer: C

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 Law

C) Historical Fact

D) Laboratory Tool

Answer

Correct Answer: A

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 sweet

B) Wearing safety goggles to protect the eyes

C) Running around the laboratory

D) Mixing random liquids just for fun

Answer

Correct Answer: B

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 $m = 200 \text{ g}$ and its volume is $V = 100 \text{ cm}^3$, the density is $\rho = \frac{m}{V}$. What is the density?

A) $0.5 \text{ g/cm}^3$

B) $100 \text{ g/cm}^3$

C) $2 \text{ g/cm}^3$

D) $20,000 \text{ g/cm}^3$

Answer

Correct Answer: C

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

Question 10

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

A) Boiling an egg

B) Using a mobile phone

C) Predicting the weather

D) All of the above

Answer

Correct Answer: D

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: D

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