Questions, Answers & Detailed Explanations
1. A mathematical model is used to predict the trajectory
of a bullet fired from a gun. Which discipline of physical
science is used to develop this model?
A. Biology
B. Physics
C. Chemistry
D. Earth science
Answer: B
Rationale: Bullet trajectory involves motion, forces, and
gravity—core physics concepts.
2. An environmental scientist monitors pollutants in a lake.
Which two disciplines of physical science does this
scientist use?
A. Physics and Biology
B. Chemistry and Physics
,C. Chemistry and Earth science
D. Earth science and Biology
Answer: C
Rationale: Chemistry analyzes pollutants; Earth science
studies the lake as part of Earth’s systems.
3. Which study involves both Earth science and physics?
A. Studying star formation
B. Mapping ocean currents
C. Classifying minerals
D. Calculating how much energy is associated with a
hurricane
Answer: D
Rationale: Hurricanes are Earth science phenomena, and
energy calculations use physics.
4. Which question could be answered with a controlled
experiment?
A. Does ice melt faster in an empty glass or in a glass full
of water?
B. How old is Earth?
, C. What is the most abundant element in the universe?
D. How do mountains form?
Answer: A
Rationale: It tests one variable—presence of water—while
controlling other conditions.
5. Which topic would be appropriate for a controlled
experiment?
A. Measuring the age of a star
B. Determining how fast different chemical pollutants
dissolve in water
C. Mapping tectonic plate movement over millions of years
D. Classifying clouds by altitude
Answer: B
Rationale: Dissolution rate can be measured while
controlling temperature, volume, and other factors.
6. Which question requires a controlled experiment to
answer?
A. How do earthquakes occur?
B. Why does the Moon orbit Earth?
