What describes a scientific statement?
Scientific statements must be falsifiable. This means that they are potentially testable—there must be some imaginable observation that could falsify or refute them. A tautology is a statement that is true by definition.
What scientists expect to happen under certain conditions?
A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge. A prediction is a statement that tells what will happen under certain conditions.
What explains why something happens in science?
Scientific theories explain why something happens, whereas scientific law describes what happens.
Which example describes a hypothesis?
Here are some examples of hypothesis statements: If garlic repels fleas, then a dog that is given garlic every day will not get fleas. If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities. If ultraviolet light can damage the eyes, then maybe this light can cause blindness.
What is a hypothesis in science?
A hypothesis is an idea or proposition that can be tested by observations or experiments, about the natural world. In order to be considered scientific, hypotheses are subject to scientific evaluation and must be falsifiable, which means that they are worded in such a way that they can be proven to be incorrect.
Is a hypothesis a prediction?
defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction. Rather, a prediction is derived from a hypothesis. A causal hypothesis and a law are two different types of scientific knowledge, and a causal hypothesis cannot become a law.
What is a prediction in science?
A scientific prediction suggests the data that are consistent with the hypothesis and thus can pertain to future and past experimental outcomes. Therefore, even though these experiments were conducted over 200 years ago, we can formulate predictions concerning the expected outcomes of the experiments.
What is a prediction science?
A scientific prediction suggests the data that are consistent with the hypothesis and thus can pertain to future and past experimental outcomes. Therefore, even though these experiments were conducted over 200 years ago, we can formulate predictions concerning the expected outcomes of the experiments.
What is a hypothesis statement?
A hypothesis is a statement that introduces a research question and proposes an expected result. It is an integral part of the scientific method that forms the basis of scientific experiments. Therefore, you need to be careful and thorough when building your hypothesis.
What is a scientific hypothesis?

In order to be considered scientific, hypotheses are subject to scientific evaluation and must be falsifiable, which means that they are worded in such a way that they can be proven to be incorrect.
Which statement best describes a scientific question quizlet?
Which statement best describes a scientific question? It must be testable. Which term describes a possible explanation of, or answer to, a scientific question that is based on prior knowledge or research and that is testable?
What is a scientific prediction?
A scientific prediction suggests the data that are consistent with the hypothesis and thus can pertain to future and past experimental outcomes. Therefore, even though these experiments were conducted over 200 years ago, we can formulate predictions concerning the expected outcomes of the experiments.
What is a predictive statement?
Therefore, by definition, a prediction is making a statement of what will happen in the future. In science, a prediction is what you expect to happen if your hypothesis is true. So, based on the hypothesis you've created, you can predict the outcome of the experiment.
What is statement of hypothesis in research?
A research hypothesis is a statement of expectation or prediction that will be tested by research.
What is statement of the problem in research?
A problem statement is an explanation in research that describes the issue that is in need of study. What problem is the research attempting to address? Having a Problem Statement allows the reader to quickly understand the purpose and intent of the research.
Which term describes a possible explanation of or answer to a scientific question?
A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis must be testable and measurable.
Which statement best describes the process of scientific inquiry?
Which statement best describes the process of scientific inquiry? Scientific ideas change over time as new evidence is discovered.
What is a hypothesis and prediction?
Hypothesis – In the sciences, a provisional supposition from which to draw conclusions that shall be in accordance with known facts, and which serves as a starting-point for further investigation. Prediction – The action of predicting future events; an instance of this, a prophecy, a forecast.
What is assumption in research?
Abstract. A researcher trying to discover the relationship between two variables must believe that the relationship between the two variables exists and can be discovered. This belief is called research assumption.
What are hypotheses?
A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review.
What is the research hypothesis?
A research hypothesis is a statement of expectation or prediction that will be tested by research. Before formulating your research hypothesis, read about the topic of interest to you.
Which describes the process of science?
The methods of science include careful observation, record keeping, logical and mathematical reasoning, experimentation, and submitting conclusions to the scrutiny of others. Science also requires considerable imagination and creativity; a well-designed experiment is commonly described as elegant, or beautiful.
Which statement best describes the kinds of questions science can answer?
2. Which statement best describes the kinds of questions science can answer? Science can answer only questions about the natural world.
What is a hypothesis in research?
A research hypothesis is a statement of expectation or prediction that will be tested by research. Before formulating your research hypothesis, read about the topic of interest to you.
What is 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.
What is hypothesis statement?
A hypothesis is a statement that can be tested by scientific research. If you want to test a relationship between two or more variables, you need to write hypotheses before you start your experiment or data collection.
What does the word hypothesis?
A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review.
Which best describes a scientific theory?
A scientific theory is a well-tested, broad explanation of a natural phenomenon. In everyday life, we often use the word theory to mean a hypothesis or educated guess, but a theory in the context of science is not simply a guess—it is an explanation based on extensive and repeated experimentation.
How is observation used by scientists?
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.
Which of the following statements describes a scientific theory?
A scientific theory is an explanation of a hypothesis that has been proven true by different experiments with consistent results over time.
