EVR 2001 EXAM 1 QUESTIONS AND ANSWERS
Which is the correct order of the scientific method? - Answers :Observation-hypothesis-
predictions-testing-results
What is the first process under the scientific method? - Answers :Observation of a
natural phenomena
What do we call variables that are kept constant in an experiment? - Answers
:Standardized or Controlled Variables
Where would you find the following sentence in a scientific article? "Our study tests the
hypothesis that bread dropped from a plate will always land on the buttered side." -
Answers :Introduction
My uncle Marvin stated that the currently accepted theory that our release of
greenhouse gases leads to climate change is not valid. When I asked what theory he
had to explain the observed changes in global mean temperatures, he stated it was just
natural phenomena. When I asked what phenomena, he said that climate had changed
in the past before humans were around but would not name a specific mechanism. How
would you describe Marvin's statements? - Answers :Based on belief
Thousands of cases of lung cancer occur in a two-year period in a city outside of
Kentucky, at rates that are double that seen in other cities in the United States.
Scientists working in that region hypothesize that - Answers :there is something unique
to the region that causing these unusually high rates.
The scientific peer-review process ensures that - Answers :scientific studies have
proper design and methods and are free from bias.
Is a scientific theory the 100% complete unchanging truth regarding a natural
phenomenon? - Answers :No. Theories are subject to future modification
Some students on a biology field trip were sitting around watching honey bees. Some of
the students noticed that bees spent more time on some flowers than on other flowers.
As they talked about this behavior, the students offered various explanations. Some
thought that the bees were avoiding predators on some flowers. Other students
suggested that some flowers may have sweeter nectar. These speculations about bee
behavior are examples of - Answers :hypotheses.
Which of the following best embodies the qualities of a scientific theory? - Answers :All
matter in the universe, including gases, liquids and solids, consists of atoms.
What might work as a control for the lion fish experiment? - Answers :A small reef
system with only native predator species present
, Formulate a hypothesis based on the lion fish image and information. - Answers :Lion
Fish, preying on native species, may result in a depletion of a certain species of fish in
given area.
If your hypothesis is that a Lion Fish population may eliminate a gobie population if
introduced to a small reef system, then what is your dependent variable? - Answers
:The local population of gobies over time in a small reef system
For the lion fish picture above, what is your independent variable? - Answers :The
predation rate of lion fish on gobies in a small reef system
Which of the following is not one of Newton's laws of motion? - Answers :If anything can
go wrong it will.
Which is an example of potential energy? - Answers :A compressed spring
If an person is going down a slide in a playground what energy is kinetic energy
converted to due to friction? - Answers :Heat
If you "feel" heat in a vacuum, what type of energy is it? - Answers :Infrared radiation
Which type of experimental approach would you use to test a hypothesis involving the
time for an estuary to return back to its previous state after a severe hurricane? -
Answers :Natural
Subjective judgments about complex environmental phenomena often lead to - Answers
:controversies and unclear conclusions and public confusion.
What section of a formal scientific article should you write first? - Answers :Materials
and Methods
Where would you find the following sentence in a scientific article? "The median mass of
the plants after treatment was 1.5 kg." - Answers :Results
Where would you find the following sentence in a scientific article? "We followed the
procedure of Kishino et al. 1985 to measure particulate absorption." - Answers
:Materials and Methods
Where would you find the following sentence in a scientific article?"The growth rate
increased by 0.5 doublings per day which supported our hypothesis that a higher
phosphate concentration increases growth rate." - Answers :Discussion
Which substance below has the highest heat capacity? - Answers :Pure water
Why can't we have a generator that is really efficient that powers an electric motor that,
in turn, powers the generator? - Answers :It violates second law of thermodynamics
