Tropisms are relatively easy to do for freshmen, but the concepts of how
they occur internally are difficult to address because the bits and pieces
don't all fit together well.  They could, however, examine how different
colors of light affect them, role of age of stem, length of time in
different temperatures, differences in germinating seeds, young plants,
mature plants, interaction of geotropism and phototropism, differences in
responses of members of different phyla (mosses usually give different
results to colors of light).
I don't have a protocol written up, but if I understand your message, you
are looking for something investigative.
