Physical Science Ch.1
What is meant by the term supernatural? Does science deal with the supernatural?
it means "above nature." Science does not deal with the supernatural because it works within nature
Specifically, what do we mean when we say that a scientific hypothesis must be testable?
it must be capable of being proved wrong.
This course will focus on
learning concepts.
In science, facts
may change.
The scientific method of Galileo and Bacon is
one of many ways of making discoveries.
Which of these is the most basic science?
physics
Of the sciences known as physics, chemistry, and biology, the most basic is
physics.
An explanation or answer that is capable of being proved wrong is:
A hypothesis
A hypothesis that has been tested over and over and not contradicted is:
A law
Galileo showed that scientific knowledge advances by
experimentation.
the scientific spirit is based upon
experimentation.
Modern science began when knowledge about the behavior of nature involved
experiments.
The scientific method is a method for
gaining new knowledge.
When a scientist is dishonest and reports false information, he or she
gets no second chance in the scientific community.
Equations in Conceptual Integrated Science are used mainly as
guides to thinking.
Hypothesis
has not been tested
Science is a body of knowledge that goes back to
humankind's beginnings.
In science, an educated guess is a
hypothesis.
In science, an educated guess is called a
hypothesis.
Most natural phenomena we wonder about
involve several scientific disciplines.
Before experimental results can be considered to be valid, they mainly must be
reproducible.
Which of the following involves passion, talent, and intelligence?
science art literature music
Direct Proportion
something gains, the other also gains (eat more candy bars, gain more weight)
Inverse Proportion
something gains, the other loses (added mass, lower acceleration)
The statement, "There are regions beneath Earth's crust that will always be beyond the reach of scientific investigation," is a
speculation.
Religion is concerned mainly with the
spiritual world.
A truly educated person is knowledgeable about
the arts. religion. science.
If experimental findings are not reproducible,
the results are not considered valid
A scientific hypothesis may turn out to be right or it may turn out to be wrong. If it is a valid hypothesis, there must be a test for proving it
wrong.
Part complete A scientific hypothesis that is deemed valid must have a test for proving it
wrong.
Why do we believe that focusing on math too early is a mistake in an introductory science course?
Focusing on math too early is a poor substitute for concepts.
What launched the era of modern science in the 17th century?
Galileo Galilei revived the view of heliocentric universe using experiments
How did Galileo disprove Aristotle's idea that heavy objects fall faster than light objects?
Galileo showed the falseness of Aristotle's claim using experimentation.
In science, a theory is
a synthesis of a large body of well-tested knowledge.
A theory in science is
a synthesis of well-tested ideas.
Using science to analyze nature
adds depth to our understanding and therefore adds to our appreciation of nature.
Science, art, and religion do not contradict one another because
all three have different domains
Technology is a tool for
applying scientific discoveries.
Something that competent observers can observe and agree to be true is:
A scientific fact
A synthesis of facts and well-tested hypotheses is:
A theory
The study of living matter is:
Biology
The study of how matter is put together, how atoms combine to form molecules, and how the molecules combine to make the materials around us is:
Chemistry
Which of the following are scientific hypotheses?
Chlorophyll makes grass green. Tides are caused by the Moon.
Radiant energy can be understood using this field of science.
Physics
The study of such concepts as motion, force, energy, matter, heat, sound, light, and the components of atoms is:
Physics
Which of the following is a scientific hypothesis?
The Moon is made of green cheese.
