because your adopted. nawh just kidding, but seriously one reason why a controlled experiment may not be possible is because...ok lets say you had an experiment of a cancer-causing chemical, they might exclude volunteers who have other serious health problems. by exerting great care in planning these kinds of investigations, scientists can discover reliable patters that add to scientific knowledge.

How can scientist test a hypothesis if it is not possible to do a controlled experiment?
If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.
After you reach a conclusion about an experiment you may find you need to experiment more?
Yes, that is possible. It's to be expected.
After you reach a conclusion about an experiment you may find you need to experiment more.?
It is certainly possible. The conclusion from your experiment may prove to be tentative and you may need to design a better experiment to improve the reliability of the conclusion, or the experiment may suggest alternatives which you may wish to explore. Most of science is about that: an experiment leads to conclusions. Further experiments result in refinements to the conclusions and, occasionally, to the replacement of earlier theories with new models.
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
Why does the ambient temperature need to be measured before and after the experiment?
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.
Scientists may do a controlled experiment to?
Communicate results

During an experiment which factors may be controlled so that researchers can draw a logical conclusion fron the experiment?

Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
After you reach a conclusion about an experiment you may find you need to experiment more?
Yes, that is possible. It's to be expected.
A factor in a experiment that can change?
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
What is the independent variable in an experiment?
Independent variable is what you, the experimenter, change or enacts in order to do your experiment

What is the differences between dependent variables and controlled variables in an experiment?
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used. Dependent variables are those which change due to the conditions mentioned above. These might be speed of the reaction, or the quantity of some product.
Why don't hot water run into washer?
Probably because you have a plugged inlet filter. All washers have this tiny filter inside the inlet hose. -Another possible reason is the electrically controlled inlet valve, it may fail .
How can a rejected hypothesis be of value to a scientist?
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
