What are the types of scientific evidence?
Primary research: Original research carried out in a clinical or laboratory setting. Examples include: observational studies and randomized controlled trials. Secondary research: Analysis of primary research, often to pool data or review the body of evidence on specific conditions.
What evidence do scientists use to support the continental drift theory Brainly?
Answer: The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. The theory of continental drift is most associated with the scientist Alfred Wegener.
What is the importance of scientific evidence?
Scientific evidence relies on data, and it is crucial for researchers to ensure that the data they collect is representative of the “true” situation. This means using proved or appropriate ways of collecting and analysing the data and ensuring the research is conducted ethically and safely.
Which explanation is based on scientific evidence Brainly?
Answer: Empirical evidence is evidence that is verified by observation or experience, rather than logic or theory. Then an explanation is based in on empirical evidence is an explanation that uses a fact that was seen or experienced.
What is your understanding of scientific evidence?
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis. Such evidence is expected to be empirical evidence and interpretable in accordance with scientific method.
What is the difference between a scientific law and a theory?
Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens.
Can scientific laws be disproved?
In science effectively all ideas are “just” theories. A basic principle in science is that any law, theory, or otherwise can be disproven if new facts or evidence are presented. If it cannot be somehow disproven by an experiment, then it is not scientific. Take, for example, the Universal Law of Gravitation.
Is gravity a theory or law?
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.
What is the best definition of a scientific theory?
” 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 experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world.”
Why is it called a theory?
A field of study is sometimes named a “theory” because its basis is some initial set of assumptions describing the field’s approach to the subject. These assumptions are the elementary theorems of the particular theory, and can be thought of as the axioms of that field.
What is a scientific theory simple definition?
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 experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world.
What is theory in general?
In everyday use, the word “theory” often means an untested hunch, or a guess without supporting evidence. But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
How do you write a scientific theory?
The scientific method has five basic steps, plus one feedback step:
- Make an observation.
- Ask a question.
- Form a hypothesis, or testable explanation.
- Make a prediction based on the hypothesis.
- Test the prediction.
- Iterate: use the results to make new hypotheses or predictions.
How do you define a hypothesis?
A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.
Is a good hypothesis falsifiable?
A hypothesis or model is called falsifiable if it is possible to conceive of an experimental observation that disproves the idea in question. A good scientific hypothesis is the opposite of this. If there is no experimental test to disprove the hypothesis, then it lies outside the realm of science.
