C165 Lesson 1-4 quiz || 100% Verified Answers.
In measuring the distance at each time, what is the independent variable? correct answers Time
what is the depenedent variable correct answers Distance
A scientist is studying the speed of water flow in rivers bull this method. Which type of study
would this be classified as? correct answers A field study
Which type of experiment is this an example of? correct answers An uncontrolled experiment
What is an experiment in which you deliberately change only one variabke and observe how a
second variable changes as a result while you hold all other variables that you control constant?
correct answers A controlled experiment
What is a model in science? correct answers A simpler system that is analogous to the real
system
Which quality identifies a scientific statement as testable? correct answers There is a way to test
it for falseness
Which term describes something that tentatively assumes what happens or how it happens in
order to test what it assumes? correct answers Hypothesis
The water flowing in a river comes from rain and snow that collected and eventually ran into
rivers. As the river flows to the sea, water evaporates from it, and from all over Earth's surface,
back into the atmosphere, where the water can fall as rain and snow again. A team carries out an
investigation, and it proposes that maybe the moist air is being cooled when the wind from west
to east forces the air upward based on knowledge that temperatures tend to decrease with
increasing height. Which term best describes this step? correct answers Formulating a hypothesis
The graph shows the volume of a copper cube as a function of temperature. What is the
relationship between volume and temperature in this plot? correct answers They are directly
proportional
The plot shows the volume of a gas measured at different pressures. What does this data tell you
about the relationship between these variables? correct answers They are inversely proportional
The following table shows elevation of a weather balloon measured as a function of time after its
launch. What do the data indicate about the relationship between these variables? correct answers
They are not correlated
What is the zero point of an x-y scatter plot called? correct answers Origin
A graph shows a positive correlation between temperature on the x-axis and total rainfall
amounts on the y axis. Does this indicate that higher temperatures directly cause the higher
