Thinking of alternative explanation for their results
according to proton electron hypothesis the nucleus of an atom of mass no A and atomic no Z is made up of A protons and (A-Z) electrons . As every atom is electrically neutral, it must contain Z more electrons they revolve around the nucleus in circular orbits. however this hypothesis was rejected later due to some reasons.
Lavoiser rejected the phlogiston theory!
Dobereiner's triads were not applicable to all set of elements. The triad could be made only for few elements. So they were rejected.
That depends on the result of the experiment. The experiment is a way to test a hypothesis, and it's completely fine if the experiment disproves the hypothesis. Ideally, though, the experiment will support the hypothesis.
No. An hypothesis is an idea put forward to explain an observation. Often you do the experiment to test the hypothesis. The results of the experiment may help you decide whether to discard your hypothesis or to test it further.
Hypothesis is examined very closely to see what it predicts, and the predictions are then rigorously tested. If the predictions are not supported by the results of experiments, the hypothesis is rejected but if they are confirmed, the hypothesis is supported.
yes
you learn from the experiment. that's the point of the experiment
the reason why a rejected hypothesis can still be of value to a scientist is because that secific hyothesis may not work for your experiment but it could work for a different experiment/theory
It's most likely to get rejected.
When we've proven that the hypothesis is false !
A hypothesis is used to make predictions. Experiments are carried out to test these predictions. If the outcome of the experiment was not as predicted then the hypothesis is falsified. It is either rejected or modified. If the outcome of the experiment confirms the prediction then that provides some evidence that the hypothesis is true.Over time, after testing different predictions, there will be a significant amount of evidence in favour of the hypothesis, and all the main alternatives have been rejected. At that stage the hypothesis becomes a theory.
A conclusion sums up all your observations,inference, and hypothesis in the experiment based on the data collected. This is to prove whether your hypothesis is accepted or rejected.
A scientific theory or hypothesis must be able to make predictions that can be tested. It must be possible to design an experiment so that there is one outcome if the hypothesis is true and a different outcome if it is false. This is what is meant by saying that a hypothesis is testable or falsifiable. If such as experiment is carried out and the outcome is not as predicted then the hypothesis must be rejected and replaced by an alternative hypothesis - or a modified version.
because it obviously had no proof and the same results were not achieved when the experiment was repeated several times by different scientists.
