Why is replication important in experimental desings?
Replication, in this sense meaning getting the same results from the same experiment, is the only way to verify that the observations were not the result of some error, or of some random factor that only affects the experiment in some cases but not all cases. For example, the result of a botany experiment may be completely different if the air temperature and relative humidity varies, as these can affect plants. For bacterial experiments, accidental contamination of containers can skew the results by introducing other organisms (that could either promote or hinder growth).When an experiment is repeated several times, there is a better chance that the data is correct and the conclusions are valid. Another term used for this concept is reproducibility.
What is purpose of doing an experiment?

Why is it important for to do repeated trials when doing an experiment?
Scientists, like everyone else, are imperfect. You cannot be absolutely sure that you have not made a mistake or overlooked something when you do an experiment, but if you do it several times and get the same result, then you can be more confident that you did it correctly. If you do it several times and get different results, that is a clue that tells you that there is something about the experiment that you have failed to understand.

Is a thermometer needed in a science experiment?

How do hypothesis help in doing some experiment?
Because it will perform a test of how two variables might be related. This is when you are doing a real experiment.
