"Because of the way Earth's axis is tilted, there is less direct sunlight per day in the winter and
temperatures drop" is mainly a statement about: correct answers Earth Science
"When water freezes the water molecules join weakly in a specific way" is mainly a statement
about: correct answers chemistry
"Being less dense than liquid water makes the ice float." is mainly a statement about: correct
answers physics
"The river freezes on its surface first" is mainly a statement about: correct answers Earth Science
An experiment in which you deliberately change only one variable, and observe how a second
variable changes as a result, while you hold all other variables that you control constant, is a:
correct answers controlled experiment
The variable that you adjust is called the________ variable correct answers independent
This is an example of employing a ______________ of the river correct answers model
If the students decide to collect data from the computer simulation on how the speed of the water
changes for different widths, but neglect to hold the rate of water entering from the source at the
, same value, they are simulating a(n) _______________ experiment. correct answers
uncontrolled
If the students keep the rate of water entering the pipe at one gallon per minute in the simulation
to see the speed of the water change as the width of the pipe is changed, the independent variable
is ____________ correct answers pipe width
If the students keep the rate of water entering the pipe at one gallon per minute in the simulation
to see the speed of the water change as the width of the pipe is changed, the independent variable
is pipe width and the the dependent variable is ___________________ correct answers water
speed
After hearing about the research, one of the students in the class asks the professor "Which is the
nicest river in America?" Why can't research in Earth science answer the simple question?
correct answers there is no falsifiable answer
A model in science is correct answers a simpler system that is analogous to the real system.
A team member notices that the winds blowing persistently from the west over a mountain tend
to produce rain on the western side of the mountain but much less rain on the eastern side.
correct answers observation
Based on knowing that temperatures tend to decrease with increasing height, the team proposes
that maybe the moist air is being cooled when the wind from west to east forces the air upward.
correct answers formulating a hypothesis
The team tests this idea in the laboratory by measuring the temperature inside a cylinder with a
movable piston so they can change the pressure of the air, simulating moving to the air to greater
height. correct answers using a model
Based on extensive research results on prevailing winds, and how air cools when it is uplifted by
winds over a mountain, the team develops a widely applicable explanation of rainfall and
snowfall around mountains. correct answers constructing a scientific explanation
The origin of water on Earth is not yet fully understood. To test one of the hypotheses, scientists
launched a gigantic observational balloon to the height of almost 130,000 feet to measure the
amounts of water in comets and asteroids based on the light reflected from these objects. The
science BEST SUITED to calculating the forces required to launch the balloon to the required
altitude is______ correct answers physics
Which physical science is the BEST to study the composition of Earth's atmosphere? correct
answers Earth Science
Which physics topic would be the MOST important in chemistry? correct answers how atoms
bond to each other because of electric attraction of oppositely charged electrons and nuclei
