Yes, that is the only way to test a scientific hypothesis because you don't know if the hypothesis if safe, right or wrong. you wouldn't hand in a homework sheet if you didn't over look it to make sure that everything is right' would you?

Did democritus perform a experiment?

only when he wanted to perform an experiment.

Is the purpose of an experiment to test the hypothesis?

Only if you are testing a hypothesis through a specific relevant experiment.

How many experiments are necessary to invalide a scientific hypothesis?

Only one, providing it is repeatable.One! Replication of the experiment result confirms the result in the scientific community.

There is only one scientific method that all scientist must follow to solve problems?

Well, technically, yes. The scientific method is to: observe, form a hypothesis, test it with an experiment, record your analysis, and decide whether your hypothesis is correct or not. Sometimes you will have to experiment over and over again because the first experiment is not accurate.

Are all hypothesis true?

A hypothesis answers a question. I could be true, but only if you prove it. So no, not all hypothesis are true.A hypothesis is just a reasoned guess. That is why you perform experiments, to test hypotheses. The data you collect from the experiment will help support whether or not your hypothesis is true.

Why is there no set path that a scientific experiment must follow?

A scientific experiment MUST follow the scientific method. The Oxford English Dictionary says that scientific method is: "a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses." That really wraps it up nicely: 1. Form a hypothesis 2. Design an experiment to test the hypothesis 3. Perform the experiment; make observations and take measurments 4. Compare the results to the hypothesis 5. Reformulate hypothesis if the results do not bear out said hypothesis 6. Repeat from step 2 with new hypothesis. Most importantly: the experiment must be able to be reproduced by other researchers. If you do something once and claim it as a new theory but no one else can replicate your results, chances are your experiment was flawed. As for the actual experiment itself: If there was only one way to design an experiment, we'd never learn much. For example, if the only way to measure something's depth was to stick a pole into it (as in a river), and this was the only experiment we could come up with, when it came time to measure the depth of the deepest ocean trench we'd be in trouble--where you going to get a pole that long? We have to have creativity and flexibility in designing experiments. What's really important is observing and measuring the results.

What must a scientist do if the hypothesis is not supported by experimental results?

You can perform the experiment again to check for errors. The best option is to just state in the conclusion the sources of error and why the experiment didn't support the hypothesis. Remember the hypothesis is only an educated guess.

Why is collaboration of scientist is necessary for the process of scientific study?

The most important reason is if a single scientist forms a hypothesis and it is proved by his or her experiment it is still only a hypothesis. Other scientists need to repeat the experiment in every way conceivable to either prove or disprove the hypothesis. Only after the hypothesis has stood up to such scrutiny may it become a theory recognized by the scientific community. Another reason is that some research is simply too daunting and complex for a single person to complete.

You want sentence with hypothesis controlled experiment and variable?

If you want to test your hypothesis with a controlled experiment, you should make sure you have only one variable.

How do you distinguish between scientific and nonscientific hypotheses?

Scientific hypothesis can be understand by scientific approach (using scientific methods & formulae etc) Nonscientific hypothesis is based on assumptions only.

What are the seven step of the scietific method?

There is no 7th step only 5 scientific method steps they are; problem,hypothesis,experiment,data,conclusion. You always need to have a problem to focus on. The hypothesis is very important, a hypothesis is a educated guess to test if your theory OS correct. You need to conduct a experiment to see if your hypothesis is correct. You need to collect data to back up your hypothesis. And last but my least a conclusion to prove if your hypothesis is right or wrong

A hypothesis only becomes a valid argument after it has been?

A hypothesis only becomes a valid argument after it has been proved. It is only a valid argument if there is proof (i.e. from an experiment).

Does scientific inquiry often begin by drawing a conclusion?

No... scientific inquiry begins by coming up with a question. From there you develop a hypothesis, test the hypothesis, alter your hypothesis if need be, test again, etc. Only after you have data that supports your hypothesis (if it ever does) do you draw any conclusions. If your data consistently does not support your hypothesis, no matter how it is modified, you may draw conclusions about your basic contentions as well. YES BUT..... what should you ask yourself in drawing a conclusion about an experiment?

Is scientific investigation expected to be certain?

Absolutely not. Hypothesis testing will never support a hypothesis, only fail to reject it.

What variable is the only one that purposely changed to test a hypothesis in an experiment?

Independent variable : )

How do you test your hypothesis?

Do the experiment. That's the only way. Unless there's an answer online or in a book :)

Why is a hypothesis a testable statement?

It is because a hypothesis is only a guess.Example:If a plant is not given enough water, then it will die.A hypothesis needs an if (condition) and a then(prediction).Then... you need to make an experiment.

Why must the parameters of a scientific experiment be controlled?

If the parameters are not controlled in a scientific experiment, then one cannot be sure what the variables are. Unless you conduct the experiment in a closed environment with only only one variable, one's results can be confusing and inconclusive.

How can you use the scientific method to explain why insects seem to suddenly appear in flour fruit and cornmeal?

1. Create a hypothesis regarding why the insects seem to suddenly appear. 2. Create an experiment to test that hypothesis. 3. Collect and analyze the results of the experiment. 4. Finally, draw conclusions whether the results support your hypothesis. For example, a hypothesis might be that insects appear in flour, fruit, and cornmeal because they hatch from eggs, which were deposited when the observer wasn't looking. To test that hypothesis, a sample experiment may be to place flour, fruit, or cornmeal in two separate jars. In one jar, put a lid on it. Leave the other jar open. For a week or so, look at the jars daily and write down whether you see insects. If you do, jot that down. These are your results. After a week or so, you can look at the results and compare them. If insects appear in both jars, the experiment did not support the hypothesis. (NOTE: that doesn't mean the hypothesis is wrong; only that that experiment did not support it.) If insects appear only in the closed jar, then you could conclude that your hypothesis was supported by the experiment. Again, that doesn't mean your hypothesis is right; only that it was supported by the experiment. Based on your conclusions, you can make a new hypothesis, which could further refine the cause of the insects.

A controlled experiment is the testing of a hypothesis in duplicate with only one factor being different?


A theory is supported by?

A scientific theory is supported by evidence. Without evidence, it is only a hypothesis.

What are the different scientefic methods?

There is only one general scientific method used in all branches of science. This involves determining the question or problem, research and gathering data, forming a hypothesis, testing the hypothesis via experimentation, recording the results of the experiment and drawing a conclusion based on the results.

What is the difference between theorem and proof?

One cannot have a theory (theorem) without proof. Theories are explanations (models with uses such as predicting on outcome of an experiment or event) for scientific laws, which only describe the phenomenon. Proof is anything that backs up a hypothesis. When a significant amount of proof is shown, the hypothesis becomes a theory due to it being accepting by the scientific community.

In science does the hypothesis have to be testable?

Yes, a scientific hypothesis must be testable. For a hypothesis to be incorporated into a theory or turned into a law, it must be testable by experimentation or observation. If it is not testable, it remains only speculation.
