You needn’t write out full sentences on your transparencies
(although you should certainly speak in full sentences). In other
words, if you’re planning to say, “Our measurements showed
that the period of the pendulum was independent of the mass of
the pendulum bob,” then your transparency should read, “Period
was independent of mass.”But don’t get carried away. It has
lately become fashionable to use “bullets” in presentations, and
one often sees transparencies that are meaningless lists of words,
abbreviations and sentence fragments. The general rule is that
the transparency text should be concise enough to be self-explanatory,but no more than that
