INTRODUCTION TO PHYSICAL SCIENCE
Question 1 Of 14
Auroras Are Bursts Of Light That Happen When Charged Particles From The Sun Interact With
Earth's Magnetic Field And Atoms And Molecules In Our Atmosphere.
Which Physical Science Is BEST SUITED Explain The Interactions Of The Charged Particles
With Earth's Magnetic Field?
Life Science
Physics
Chemistry
Physics Can Explain The Interactions Of Charged Particles With The Earth’s Magnetic Field
Because Magnetic Fields Are Forces.
Question 2 Of 14
The Physical Science That Is BEST For Finding The Best Locations To Drill For The Petroleum
Used To Make The Candles Is Earth Science.
Earth Science Is Best Suited To Study Earth’s Structure, Including The Mechanisms And Likely
Locations For Petroleum Reservoirs To Collect.
Question 3 Of 14
Downloaded by NELSON KIIRU ()
, lOMoAR cPSD| 26582732
The Science BEST For Studying How Hydrogen Sulfide And Carbon Dioxide React Is
Chemistry. Chemistry Focuses On The Study Of Atoms And Molecules, Their Structures, And
Their Interactions To Form Various Substances.
Question 4 Of 14
The Science BEST For Studying Photosynthetic Bacteria Is Life Science.
Life Science Focuses On Environments, Biological Entities, And Many Other Related Fields.
Question 5 Of 14
Which Of The Following Terms Best Describes A Research Project That Involves Sending A
Space Probe To A Distant Asteroid To Land On It And Collect Data?
A Controlled
Experiment A Field
Study A Laboratory
Experiment
Even Though The Scientists Are Not On The Asteroid, They Are Conducting Data Collection In
The Field.
Question 6 Of 14
A Main Reason To Do A Field Study Rather Than A Laboratory Experiment Is If
Question 7 Of 14
Which Of These Fields Depends The MOST On
Observational Studies? Physics Earth Science Chemistry
While Scientists Today Have Many Techniques And Procedures To Replicate Unique
Experiments That Answer Can Answer Questions About The Earth, Most Of The Data
Collected Is Still Observed.

Question 8 Of 14
The Kinetic Theory Of Gases Is Based On The Assumption That The Molecules That Form The
Gas Are In Random Motion And Bounce Off The Walls Of Their Container And Off Each Other
As If They Were Billiard Balls. The Forces Between Real Molecules Are More Complicated.
This Is An Example Of
An Observational Study Focuses On Collecting Data And Observing Phenomena In The
Field Or Laboratory.
Question 9 Of 14
Why Can’t Astronomers Carry Out A Scientific Research Study To Determine Which Visible
Star, Other Than Our Sun, Is The Nicest?
The Hubble Telescope Has Better Uses.
Existing Telescopes Aren’t Powerful Enough.
There Is No Way To Prove Any Answer Wrong.
A Project Of That Sort Cannot Get Funding.
“Nicest” Is Subjective. Consider The People Who Like Summer Versus Winter, Or Vice Versa.
Question 10 Of 14
Galileo Found That When Air Resistance Can Be Ignored, Heavier And Lighter Objects Fall In
The Same Way. He Tested This Rule And Confirmed It Was Consistent With All Available
Data.
The Rule Galileo Found Can BEST Be Described As A
The Rule Galileo Found Was A Tested Conclusion Describing Something Very Specific That
Happens, And Was Supported By All Available Data.
Question 11 Of 14
Which Of These Describes A Statement That Has Usually NOT Yet
Been Tested? A Hypothesis A Model A Theory A Law
Downloaded by NELSON KIIRU ()
, lOMoAR cPSD| 26582732
A Hypothesis Is A Testable Statement About How Something In Nature Works. It Is Typically
The Best Tentative Assumption That Researchers Can Make Based On The Evidence They
Already Have At That Point.
Question 12 Of 14
It Is Often Said That You Can Never Prove A Scientific Theory Right. Why?
It Is Impossible To Directly Test Every Single Instance In Which It Applies.
A Theory Is Just A Guess.
Science Can Never Prove Anything Either Right Or
Wrong. A Theory Becomes A Law Once It Is Tested
That Thoroughly.
Laws Are Statements Of Simply What Is Observed In All Available Experiments, While
Theories Are Explanations And Typically Apply To Whole Groups Of Phenomena. Laws Do
Not Become Theories. Question 13 Of 14
Which Of These Is Generally Regarded By Scientists To Be The Basis For Deciding Issues In
Science? Personal Faith In The Particular Idea Proposed Whether The Idea Is The Simplest One
The Researcher Can Think Of The Reputation Of The Researchers For Careful Work Empirical
Evidence Including Experiments And Observations
Laws And Theories Are Based On And Supported By A Wealth Of Evidence And Facts.
Question 14 Of 14
Which Of The Following Describes How Scientific Investigations Are Carried Out?
Scientists Settle Scientific Issues By Staging A Debate To Decide Which Side Gave The Best
Presentation.
Scientists Settle Scientific Issues By Forming A Consensus In The Scientific Community
About Which Explanation Is The Most Appealing.
Scientists All Follow The Same List Of Four Steps To Make A Discovery: Observe
Something, Hypothesize About It, Test The Hypothesis, And Form A Theory.
Scientists Use Different Procedures But Rely On Evidence And Testing To Confirm Their
Ideas. Scientists Follow Many Different Procedures, Depending On The Nature Of The
Research Problem And Their Own Creativity In Finding Ways To Gather Information.
