They are not necessary unless your instructor specifically says so. However, multiple trials are always favorable just to see if your results the first time are consistent.

We do multiple trials to ensure the validity of our results; we want to be sure that our results are not caused by events outside of the experiment. Multiple trials are always encouraged if you have the time and resources.

Hope this helps,
