“A scientific theory is
a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experimentation
.
Which statement is an example of a scientific theory?
A scientific theory is a broad explanation that is widely accepted because
it is supported by a great deal of evidence
. Examples of theories in physical science include Dalton’s atomic theory, Einstein’s theory of gravity, and the kinetic theory of matter.
What is a scientific theory theory?
A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. … A theory not only explains known facts; it also allows
scientists to make predictions
of what they should observe if a theory is true. Scientific theories are testable.

A scientific theory is
widely accepted explanation that is supported by evidence
. Hypotheses and theories are both proposed explanations for a scientific question. “Give examples of different ways in which observations are used in scientific inquiry.”
What differentiates a scientific theory from a scientific hypothesis?
In scientific reasoning, a hypothesis is
an assumption made before any research has been completed for the sake of testing
. A theory on the other hand is a principle set to explain phenomena already supported by data. … And that’s where we see the difference between a hypothesis and a theory.
What is a theory example?
The definition of a theory is an idea to explain something, or
a set of guiding principles
. Einstein’s ideas about relativity are an example of the theory of relativity. The scientific principles of evolution that are used to explain human life are an example of the theory of evolution. noun.
How are scientific theory formed?
Scientific theories are created
through the process of the scientific method
. Observation and research lead to a hypothesis, which is then tested. … Over time, a hypothesis can become a scientific theory if it continues to be supported by additional research.

What is a scientific theory and a scientific law?
In general, a scientific law is
the description of an observed phenomenon
. It doesn’t explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory.
How many scientific theories are there?
Albert Einstein described
two types
of scientific theories: “Constructive theories” and “principle theories”. Constructive theories are constructive models for phenomena: for example, kinetic theory. Principle theories are empirical generalisations such as Newton’s laws of motion.
Which statement accurately describes scientific inquiry?
Scientific inquiry may lead to explanations that
combine data with what people already know about their surroundings
. This is because scientific inquiry starts with observations which lead to hypotheses. These hypotheses are then rigorously tested through experimentation.
Why do scientists consider any hypothesis valuable?
(1)
A hypothesis requires no further investigation
. (2) A hypothesis may lead to further investigation even if it is disproved by the experiment. (3) A hypothesis requires no further investigation if it is proved by the experiment.
Which reasons explain why psychologists use the scientific method?
Psychologists use it because it is
the most objective method known for obtaining dependable knowledge
. The science of behavior and mental processes. That seeks to describe and explain aspects of human thought feelings, perceptions and actions.
Which statements describes a scientific law?
A scientific law is a statement
describing what always happens under certain conditions
. Newton’s three laws of motion are examples of laws in physical science. A scientific law states what always happens but not why it happens. Scientific theories answer “why” questions.
Which statements are true of all scientific endeavors?
All scientific endeavors are
a systemic process
. All scientific endeavors involve observation. All scientific endeavors involve experimentation. All scientific endeavors involve the collection of information.
Which statement can be described as a scientific law?
Which statement describes a scientific law?
A law is a proven fact that cannot be changed.
What are scientific theories quizlet?
Scientific Theory.
A well-tested explanation that unifies a broad range of observations and hypotheses
and that enables scientists to make accurate predictions about new situations.
What are theories in science quizlet?
Scientific theories are
well established explanations of evidence, or explanation of an aspect of the natural world based on repeated observations
.
Which of the following statements best distinguishes hypotheses from theories in science?
Which of the following statements best distinguishes hypotheses from the theories in science?
hypotheses usually are relatively narrow in scope, theories have broad explanatory power
.
How are hypotheses and theories similar?
A
hypothesis proposes a tentative explanation or prediction
. … A theory, on the other hand, is a substantiated explanation for an occurrence. Theories rely on tested and verified data, and scientists widely accepted theories to be true, though not unimpeachable.
What is one of the key differences between scientific theories and hypotheses quizlet?
A hypothesis is
an explanation for observations
. A theory is an explanation for what has been shown many times.
Is a scientific theory a fact?
In science,
theories never become facts
. Rather, theories explain facts. The third misconception is that scientific research provides proof in the sense of attaining the absolute truth. Scientific knowledge is always tentative and subject to revision should new evidence come to light.
What theories are used in research?
Theories such as
interactionism, phenomenology, and critical theory
can be used to help design a research question, guide the selection of relevant data, interpret the data, and propose explanations of causes or influences Previous articles in this series have addressed several methodologies used in qualitative …
Which statement is a scientific claim?
Scientific claims are
statements made in science based on an experiment
. They’re claims just like you might find in other classes, but they are backed by experimental data you created, as well as the work of other scientists. Let’s look at an example.
Which of the following is a characteristic of a scientific theory?
Theories are
concise, coherent, systematic, predictive, and broadly applicable
, often integrating and generalizing many hypotheses.” Any scientific theory must be based on a careful and rational examination of the facts.
What are two scientific theories?
And it’s not the job of theories to become facts—they use available facts to make sense of a broad concept. Scientific theories explain some of the most familiar and complex phenomena. A few of the best-known scientific theories are
the theory of gravity, the theory of evolution, and the theory of relativity
.
What is the role of theory in scientific inquiry?
Theory is both the beginning and the end of scientific research. It serves as
the basis for generating hypotheses to test propositions that explain observable empirical phenomena
, but in the end it also provides the general explanations and knowledge of a field.
How are scientific theories and scientific laws similar?
Scientific laws are similar to scientific theories in that they are
principles that can be used to predict the behavior of the natural world
. Both scientific laws and scientific theories are typically well-supported by observations and/or experimental evidence.
What are the most important scientific theories?

- Hubble’s Law of Cosmic Expansion.
- Kepler’s Laws of Planetary Motion.
- Universal Law of Gravitation.
- Newton’s Laws of Motion.
