| You should window your timestreams so there's less spectral leakage in your FFT's and the peaks are more well-defined. I find Hanning to be a good, all-purpose window, and will make your FFT's look a lot better, IMO (and will also save you the time of having to answer your students questions about why all the peaks have 'wings', unless it's specifically part of the scope of your course).
