WGU C-165 Integrated Physical Sciences
1. What is science?
a) Collection of knowledge and a process of discovering how various parts of
the universe interact with each other.
b) More than just observing or describing nature.
c) Asks and tries to answer questions about nature.
d) all of the above.
Ans: d) all of the above.
2. What does the word Scientia means?
Ans: Knowledge.
3. Physical sciences is.......
Ans: The study of non-living systems.
4. Life science is......
Ans: The study of living things.
5. Physics
a)The study of forces
b)The study of energy
c) The study of motion
d) All of the above
Ans: d) All of the above
6. Chemistry is
Ans: The study of atoms and molecules, their structures, and their interactions to form
various/new substances.
7. Earth Science
Ans: Structure and composition, processes that change. Earth, (volcanic and seismic
activity).The study of Earth and other planets, including their physical structure, materials,
and processes.
8. Modern Earth science
, Ans: Study of other planets.
9. Physical sciences includes:
Ans: Physics, Chemistry, Earth and Space sciences.
10. What they all have incommon (physical sciences)?
Ans: They all have a common goal: to understand and identify the relationships that exist
in the natural, non-living world.
11. Explain what is meant by the physical sciences. How are they different
from life sciences? What disciplines make up the physical sciences?
Ans: Physical science studies non-living systems, as opposed to life science, which
studies living systems. Physics, chemistry, and Earth and space sciences are all physical
sciences.
12. All living and non-living things are made of extremely small particles
called?
Ans: Atoms.
13. Atoms can bond together to make a wide variety of?
Ans: Molecules.
14. Who/What make up every substance that we know of?
Ans: Atoms and Molecules.
15. What do earth scientists investigate primarily?
Ans: 1. Earth's past and current structure, 2. composition, 3. magnetic and gravitational
fields, 4. volcanic and seismic activity, 5. weather, climate, and similar topics.
16. A scientist is studying how ice crystals form in cirrus (thin, wispy) clouds.
Which field(s) of science is she studying?
a) physics
b) both of these
c) Earth science
Ans: b) both of these (Ice crystals formation in clouds requires knowledge of both physics
and atmospheric science.
, 17. Fossil fuels are organic materials formed over millions of years from dead
plants and animals that were subjected to extreme temperatures and pressures
in Earth’s crust. Which of the following sciences are BEST used to explain how
fossil fuels formed?
a) only chemistry and Earth science
b) only physics and Earth science
c) only biology and Earth science
d) physics, chemistry, and Earth science
Ans: physics, chemistry, and Earth science. All three sciences are needed to
understand the formation of fossil fuels.
18. When fossil fuels burn, their organic molecules interact with oxygen to
produce carbon dioxide and water. Which of the following sciences is BEST used
to explain how fossil fuels burn?
a) chemistry
b) physics
c) Earth science
d) biology
Ans: chemistry. Chemistry studies how molecules interact to form new substances.
Therefore, chemistry is the best suited to study the burning of fossil fuels.
19. All of the following are studied by physical science EXCEPT__________?
a) an explosion of a distant star
b) how lightning bolts form
c) an earthquake happening in the Pacific Ocean
d) the development of sugar substitutes that do not alter food taste
e) the feeding patterns of whales
Ans: The feeding patterns of whales. Whales are living organisms, and so they fall
within the realm of biological science.
20. Scientists analyze the forces involved in a serious vehicle collision.
a) physics
b) chemistry
c) earth science
d) all of the above
Ans: physics
21. Scientists develop a solar cell made with large organic molecules that can
undergo chemical changes and produce electricity from sunlight.
a) chemistry
b) physics and chemistry
